The entire country of Portugal ran solely on renewable energy for six days in a row in November 2023. Portugal produced 1102 GWh of renewable energy from wind, hydropower and sun, surpassing its demand of 840 GWh, which allowed it to even export electricity to Spain. It’s a record. About 60% of Portugal’s energy comes from renewable sources today and is expected to run 100% on renewables before 2045.
Resizer, hydro power is significant in Portuigal, but also quote, "It doesn’t mean fossil fuel plants weren’t operating" The reason fo that is renewables' defficiency in critical crite ria for a stable grid supply. You cannot run a grid on asynchronous renewables alone.
@@iareid8255 That means nothing. The energy was there. The actual consumption energy. I swear to god I always come to videos on renewable energies and there's people hellbent on invalidating any good that is being done. Every time.
Jean, grid supply needs a specific type of generator, renewables simply do not meet the requirements. They are a dead end and just make electricity more unreliable, more unstable and much more expensive. Hydro is the only renewable that does0 meet those criteria. You cannot go against the physical constraints and no amount of tecnical improvement of renewables will overcome their deficiencies. Persisting is s just ignoring reality.
The legacy of these abandoned wells must include following the money of the original companies and investors. They took the money and ran. Part of investing is compliance with EPA and local laws. Greed kills.
Shame on BBC for spreading Delta Airlines' greenwashing. Global aviation represents 2.4% of global anthropogenic CO2 emissions, but roughly 3.7% of anthropogenic radiative forcing in 2018 came from aviation, and aviation emissions are growing 5% per year. Sostainable Aviation Fuel (SAF) is not a real solution. It may have net zero CO2 emissions, but Lee et al (2021) estimates that global aviation in 2018 had a radiative forcing of 100.9 mW/m2, of which 57.4 mW/m2 was from contrail cirrus clouds, 34.3 mW/m2 from CO2, 17.5 mW/m2 from NOx, 2.0 mW/m2 from stratospheric water and 0.94 from soot. In other words, SAF will only solve a third of the problem, but does nothing to address the other two thirds of the problem. Hydrogen planes are potentially worse than today's planes, because hydrogen planes will emit even more water vapor, leading to more contrails and more cirrus cloud formation, plus hydrogen tanks are high problematic from an engineering point of view. The only real solution is battery electric planes and VTOLs for short distance flights and airships and hybrid airplanes for long distance flights. Another option is switching more travel to electric high-speed trains or hyperloops. Hybrid airplanes can switch to their electric motors when passing through atmospheric conditions where cirrus cloud formation is likely. Until electric and hybrid planes are developed, the only solution is for planes to try to fly around areas in the atmosphere where cirrus cloud formation is likely, and the BBC should have asked Delta whether it would spend the extra money in fuel and incur the disruption of flight time schedules to do that. It was very poor journalism by the BBC to not understand the science and to not ask Delta the relevant questions, rather than letting the airline spew its greenwashing nonsense about SAFs. The methane from fossil fuel sources has a GWP-20 (global warming potential over 20 years) of 82.5 and a GWP-100 of 29.8 (IPCC AR6 WGI, 2021), meaning that 1 gram of methane has the same greenhouse warming effect as 82.5 grams of CO2 over 20 years or 29.8 grams of CO2 over 100 years. which is a lot more than "a greenhouse gas several times more potent than CO2", as this video said at 02:02. Since methane lasts an average of 12 years in the atmosphere (technically, its perturbation time), it has a higher impact in the short term.
You claim that electric planes are what's needed but the data on electric cars suggests that evs are worse than ICE vehicles for the environment, when taking into account everything including manufacturing, sourcing energy, road maintenance, product lifetime, and recycling of finished product.
In my area a old pipe line was cut and since nothing seemed to be coming out they simply burried the cut pipe next to the house they were building. Of course a house with the family in it blewup killing the family. Developers are still resisting regulations restriting building on top of old oil fields.
@@sophiadaly4712 Firestone, Colorado, USA. What's weird people go nuts when oil companies want to drill anywhere near neighborhoods but developers build houses with working oil fields in them and in Firestone right over an working oil field with working under ground gas lines. Like, often these lines in old fields do not have allot of gas coming through them and this methane does not have a smell so cutting a pipe does not seem like a big deal. In the Firestone case the contractor simply cut the pipe and filled in the foundation hole. Again, no smell because it is pure methane so the relatively new house blew up killing a family.
There is a difference between renewable energy and emission-free energy. Bio-fuel emits CO2 and other bad stuff. We need to transition to 100% emission-free, basically solar, wind, and batteries (SWB). When I got going in climate change, renewable sounded great. In fact, I founded a group called Renewable Taos. As time went on and we made local progress, we realized that we really need to focus on emission-free. That is the only proper focus to avert catastrophic climate change. It's a transition, so bio-fuels have some reason. But, they are actually very dirty. SWB is the actual solution. Cooking oil and ethanol are actually bad sources of energy.
Thank you for sharing your knowledge about renewable energy. I completely agree with your focus on emission-free energy sources like solar, wind, and batteries. Speaking of batteries, have you heard of the Segway Portable PowerStation Cube Series? It's a versatile powerhouse with a massive capacity, powerful output, and fast recharging time. It's perfect for outdoor enthusiasts and RV lovers looking for reliable power backup solutions.
22:00 CO2 is not " bad stuff ".IT is green plant food used in natural chemical process ( photosynthesis) which emits oxygen. Do you know how important that is?There have been times in earths atmospheric history when the proportion of CO2 to other atmospheric gases has been higher than it is now ( now the proportion is a meagre 0.004 %) - recently some supposed renewable energy savvy Congress members had no idea of the proportion and made wild stabs ( when asked )of 6% up to 8%.These are people making policy to reduce CO2 emissions!!! Just another thing to zealots playing God with earths atmosphere.Battery storage.Batteries go flat,can be recharged,but not indefinitely, contain dangerous chemicals and take up space.When useless ( after not very long relatively [ compared to nuclear ],how are you going to dispose of them? Landfill? Ugly, much like turbine blades. Landfill batteries will eventually leak to ruin soil and groundwater, then to rivers and finally the oceans.I won't alarm you any further but this whole renewable energy phobia refuses to entertain the drastic consequences that will follow the construction of the " planet utopia ".@user-hh6ex9md4w

Pity the latest figures say we've hit 1.54 this year having hit 1.5 for periods over earlier years. Most notable this year was the size of the jump, that the oceans around el nino don't look like they normally do which is to say instead of looking cooler they look hotter. The latest predictions pointout we're adding renewable on top of existing fossil fuel. Renewable is being used to meet new demand not replace old sources. The best predictions say 1.7 by 2030 and 2 degrees within 15 years or by 2038 and these maybe conservative as tipping points have been reached and the tipping we were warned of has occurred. The huge loss of albedo from missing ice means massive ocean warming. Boreal forests are converting themselves to tundra, temperate and tropical forests to grasslands in massive wildfires because we've taken too long. The roller coaster is moving and now natural processes will multiply the effects of the emissions we have failed to reduce. Climate zones are determined by latitude, altitude, topography and wind and ocean currents driven by temperature differentials. We've shifted those currents, slowed them and induced more, slower moving and larger oscillations in the jetstream. This means faster more severe, longer lasting droughts, longer cold snaps with heavier precipitation causing flooding and record snows. Our infrastructure built for one climate is going to face extremes and frequencies it wasn't designed for. Our crops and the biomes they evolved in will nolonger match the climates they are planted in. Fruit trees will set leaves instead of flowers due to warm winters, grain will rot in floods and prematurely die and dry off in heatwaves, continuing to push up world food prices, while leaving growing numbers hungry. Topsoil will be eroded in floods and blown away as dust at alarming rates. This bbc feel good is talking about the solutions to yesterdays problems, that were not able to be adequately implemented on time. The world has moved on and we need new solutions to adapt to the consequences of our failure to respond in time.
Hmm your message sounds suspiciously like a WEF sales promo 🤔 😂😂😂😂 What utter tripe you just posted, tell me the solution....TAX THE POOR! RESTRICT THE MOVEMENT OF THE POOR ONLY! FORCE THE POOR TO EAR LESS MEAT! CONTROL THE POOR!
Well the new demand could be met with fossil fuels instead, so it’s a good thing it’s not happening. And population will start decreasing soon, the energy demand will go down, so at that point the more expensive plants, the fossil ones, will be shut down first.
@@deaththekid3998 or we find new ways to use the energy as we have in the past, like data centers. Plus the plans of opec aren't to supply the rest of the world with renewable dependent infrastructure but cheap fossil fuel cars etc. Waiting for the predicted population decline will be to long as natural forcing from tipping points passed will have kicked in. Renewables are dependent on finite resources and have a limited lifespan, it's our energy demands that have to drop. There's a reason the richest people in the richest countries have the biggest footprint. Our population could half but our footprints could increase 100 fold and still not satisfy the growing demand.
It's not new drilling causing the problem but old drilling and pipes where developers build on top of these old fields. Developers have pushed to prevent regulation's where they can build. Often developers can get abandoned oil drilling fields cheap and clean off the surface equipment and have a place to build without the people they sell to ever knowing the history of the land to which their buildings are built on.
@@stanleytolle416 it all starts with drilling and indeed already before anything gets to the end user, the pollution already starts through leaks, energy use, cobalt use and so on.
@@flemlion13 this drilling is often in the middle of nowhere. Like the Firestone case was originally on a desolate hillside not even good for cattle grazing. Fifty years before oil drilling took place. Often mineral rights and surface rights are all mixed up. Like oil and coal companies have rights to extract under ones house or they have done it. Uncapped wells, coal mines, underground fires are all over the place with no mapping. Of course developers want as few regulation's as possible. Surface soil testing is required due to expanding soil, another story, but history of land use is not. A little wild wild West here.
In his book Rethinking Humanity, Tony Seba along with James Arbib, the founders of Rethink X, say that not only is ditching fossil fuels possible but economical. They say that the transition to solar, wind, and batteries will happen for economic reasons meaning that in 10 years time, most fossil fuel projects will become stranded assets. It’s worth a read
Their new book Bighter is a great read, it is a real positive but grounded explanation of current state of affairs and the future. And it is bright, brighter than we think:) Well if it all works out:P
Hi. Great content, thanks. The "sand battery" is better called a "recoverable heat sink", but what a great idea. Not much different to my Grandma's ancient woodfired Aga cooker that heated up the cast iron and stone surround which then released the heat during the night to keep the whole Robinson mansion nice and cosy. The washing was hoisted up to the ceiling and dried in no time. (By "mansion", I mean---nah, never mind.) Cheers, P.R.
Vietnam, the Philippines and Malaysia should first hold negotiations with each other on the East Sea (Spratly Islands) dispute, and then discuss this issue with China.
Why the representative person from the IAEA was not asked about the reason for tripling nuclear energy despite the increasing cost of nuclear energy production at about %33 and long construction timeline while there is a need to urgent solutions?
Of course. It is just a matter of time. Regeneratives are available right now, and would greatly accelerate an all-sustainables global economy. The build out of primary inputs will take some time. But, at some point renewables heavy energy production would be the norm.
With global temperatures hitting record highs, and extreme weather events affecting people around the globe, this year’s UN climate change conference, COP28, is a pivotal opportunity to correct course and accelerate action to tackle the climate crisis. COP28 is where the world will take stock of progress on the Paris Agreement - the landmark climate treaty concluded in 2015 - and chart a course of action to dramatically reduce emissions and protect lives and livelihoods.
My honest question: Do we have enough raw materials (also including recycling) to make the energy transition ? I am on with renewable and EV, but it's my biggest concern :/
Having completed an Open University course on renewables, I believe there are plenty of existing sources with more to be discovered. They really can power the world. Wind, solar and hydro already supply over 40% of UK electricity for much of the time. Coal is zero for most of the time thankfully. Its 11.25 am and just now renewables were supplying 54.8% of demand. Fossil fuels (gas) 14%. You can get up to date info from National Grid: Live. BTW the course isn't to degree level but it is one of their free one.
"You want coal? We own the mines." "You want oil? Well, we own the fields." "You want nuclear? We own the uranium." "You want solar and wind? Well, we own the- oh, erm... Solar and wind just isn't feasible, you see?"
There is a type of seaweed that eliminates the vast majority of methane emissions from cattle. Very little is needed in a cow's diet to have this effect at low cost. A regulation to require this seaweed to stop bovine methane emissions would be very cheap to implement and have an enormous effect. Not surprisingly the beef and dairy industries do everything they can to block such regulations from being passed and they won't self-regulate their methane emissions.
Sustainable Aviation Fuel math: 400M gallons = 10% of the current market use Then 5M gallons currently used is 0.125% of aviation fuel usage. Gold Star! ⭐️
Burlington Vermont is not in the sunbelt and Vermont gets quite cold. What interests me is the rapid development of deep geothermal. Depending on the rock structure, a deep well should be able to produce water hot enough to spin an electric turbine.

The most important thing is not where the energy comes from, it is how, and in what proportion, we use it. Firstly we have to reduce our standard of living, we don't need all these products and services to live happily and healthily.
The world should build sand batteries hand over fist! I still hear the old mantra: "The wind doesn't blow and the sun doesn't shine!" This problem is non existant anymore! BBC go and promote this tech ASAP!
The BBC's job, across it TV and Radio, is to be positive. It doesn't matter how bad the facts are! Re: Airlines, much quicker would be better investment in public transport, train, bus and boat, so that planes trips less than 4 hours long can be banned. Because it's these short flights that are the most polluting!

Burlington Vermont only has 44k people. If you REALLY want to see what high penetration renewables looks like, study South Australia. They're the hightest wind and solar per capita in a larger city in the world
Yes. It's far more lucrative to go with green energy, conservation, smart power upgrades, regenerative portfolios, and natural abundance. The hydrogen economy is also a part of the campaign, standing alongside best practices, as well.
Some are powered by methane derived from farm animal waste but that's going to happen everywhere. Maybe fuel cells but they still need electric motors. There are already some huge electric articulated lorries so maybe there will be some big electric tractors soon.
Nice, but greenwash from the aviation industry. What needs to be said is 'we need to fly less' - but will an industry based on making profit from air transport ever say 'consume less to reduce the footprint'?
NO. The facts are out there, but they are kept from us as it undermines their whole story. WIND for example. What they TELL YOU wind farms "produce" in terms of energy, is based on "name plate capacity." This is what a turbine will produce at maximum power. ie. when the wind strength is JUST RIGHT over a 24 HOUR period. 😄 HOWEVER 🙁 From proven data, wind farms rarely produce even 20% of what is claimed, due to either downtime for maintenance or TOO MUCH/TOO LITTLE wind. Hence gas fired power stations are still kept on stand-by ( at great extra cost ) to fill the gap when wind & solar cannot cope with demand. We are saddling our kids and grand kids with TRILLIONS in debt, for a system that DOES NOT WORK. 😡

I don't know about saying Burlington is 100% renewable, this only seems to refer to the electricity grid, not transport, also not city heating according to one website, whatever that means exactly, might be a lot in their climate. Transport is usually around 30% of emissions. If they had gotten everyone to buy an electric car they would have mentioned that somewhere surely, this would cut transport emissions to about half, 15%, still perhaps not enough. It is common to talk about being 100% renewable without counting transport, this seems rather self-deluding avoiding addressing the probable need for walkable, "15 minute", cities or communities bypassing transport where possible.
Having worked in the clean energy and renewables space for many years, I’ve seen a lot of misinformation touted in these interviews. Renewables are an intermittent source of energy. When comparing the price of renewables to other sources like baseload nuclear or fossil fuel energy generators, you need to look at the total system costs. These system costs include the transmission infrastructure needed to transport energy to consumers, and also the enormous amount of storage that’s needed when the renewables aren’t generating anything. If you include the cost of all this extra infrastructure, it is much higher than the cost consumers currently paid for their existing baseload generators. Moreover, the area footprint for renewable generation is much larger and conventional based generators. We need to ask ourselves where we’re going to get all the necessary minerals to realise these nets zero fantasies by governments where are we going to get a cobalt, nickel vanadium, silver?? There aren’t enough known reserves for these minerals at the present time? All these discussions about sustainable aviation, fuels are fanciful. Here, again. You need to look at the total system costs, which include harvesting all the biomass and organic resources, transport, costs and refining costs. How much landmass are we going to have to commit for these biomass fuels? And is that the most sustainable outcome for this biomass?
The new tech can make a difference if power generation is a human right and we can let middle and lower incomes pool their money together and fund a windmill or something literally giving the power to the people.
"I literally lie awake at night scared of societal collapse and human extinction." Speaking as a researcher, that unfortunately means you're one of the small percentage who understand how big and intractable the threats are. I lose a lot of sleep too.
The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres. That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd. The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.
In October 2022 UN Under Secretary General for Global Communications Melissa Fleming speaking at the WEF event said that any search on Google always returned their data on climate change. She then stated that “we (the UN) own the science” So much for independent climate science?
Looking forward to seeing how the nuclear industry returns in strength with small modular reactors. I'm also happy to see Airbus developing hydrogen powered airplanes. We can produce the hydrogen for free from nuclear power plants!
The renewable energy itself is not enough, unfortunately I would add, some nuclear plants are necessary, in Italy we don't have it but we buy loads of energy from France that produces it with that.
Renewable cannot solve the problem alone. The proper mix of energy sources for co2 reduction is made by nuclear for the baseline, renewable and gas where the last two are not available.
@@hunterspeak4370 this is not true. Renewable cost per MWh is comparable to the nuclear cost per MWh for plants built in 5-6 years, with the advantages of scalability and low impact
No. The overnight costs of a gen 3 nuclear plants is €6B, which makes the price per MWh competitive to gas plants. The financial costs depends on the government decision to subsidize the construction of the nuclear plants, like they do for the renewables.
What does upstate New York mean ? State of New York rather than the city of New York? Upstate= in the mountains? or upstate= in the north of the state ?
We really have to ponder this: why do the UK citizens pay a few times MORE than most people in the world when the renewables can now be even cheaper than energy from fossil fuels? To put it into perspective, in some Asian countries that only use natural gas to generate electricity, they pay only 10-12p per kwh (without standing charge) while we are paying bloody 27p per kwh + 35-40p standing charge per day! How could ours be that expensive? There must be something wrong with our system! Our government must fix this or everyone in the UK will continue to suffer badly, both socially and economically.
Renewables are more expensive when you take into account all the costs necessary to deliver a stable electricity supply (power lines to transport electricity from thousands of disparate solar and wind farms far from where the electricity is used, energy storage because renewables are intermittent and a stable electricity supply is needed, grid balancing to respond to changes in generation, the cost of maintaining stand -by natural gas power plants to cover renewables when they fall short, plus all the maintenance on the above plus all the interest cost on the vast amount of infrastructure that needs to be built to deliver all of this - much of the renewables were built with near zero interest rates). Also by inspection we know it is more expensive because if it were the cheapest it would not need subsidy and the UK would have high energy industries setting up on its east coast to take advantage or the wind energy from the north sea.. but in reality renewables are given subsidies, gas power stations are taxed, and high Energy industry is leaving the UK. So when someone says renewables are cheapest they are ignorant or gaslighting. Hopefully there will be more technologies that emerge that are more practicable than current wind and solar.
DIGITAL ENERGY SERVICES as well as extensive services up to and including operation and maintenance services for PV power plants round off the SMART CONNECTED RANGE.
Burlington might have 100% renewable energy, but it is far from zero carbon emissions. In fact with one third of its electricity coming from burning biomass, it is in fact a big emitter of greenhouse gases.
Not always recent. The UK is importing woodchips from Canada. Some of this is from old forests which are supposed to be protected. Also it doesn't make sense to cut the wood, trans port to the coast then send it across the Atlantic, then transport to the Drax power station near Selby in Yorkshire - some distance from the coastal port.@@biggusdoggus
@@ralpharmsby8040 it rather depends on what the exact criteria is for recent, but the age of wood biomass is several orders of magnitude less than coal, for example. I agree that transporting wood such a long way does not make sense. I have not read a LCA for the case you mention, but the OP was about Burlington, and the plant there claim to primarily source biomass from the local area.

@@containedhurricane How much space do ground receivers for space-based solar take? But seriously, “too much space” isn’t a defensible argument. There’s plenty of rooftops and parking lots, in addition to wide open spaces. Ultimately, though, it’d take 20 years to get space-based solar working at meaningful scale, IF we started now with an all-in effort. Ground-based solar is doubling every 2-3 years, in large part because you don’t need billions of dollars and tremendous engineering efforts and international cooperation to put up a solar panel. I do not understand the obsession with doing the most technologically difficult and ridiculously expensive approaches to getting rid of fossil fuels, when something simple and cheap is right there in front of our noses.
@@davestagner I bet it will require the space of a desert to match the power gained from a few space-based solar panels. If the space-based ones weren't potentially more lucrative in the long run, the UK scientists wouldn't plan to make them
@@containedhurricane Has a government invested at least a billion dollars into the idea? Is there a timeline? Could they have it in production by 2030? If the answer to any of these is “no”, then it’s going to have a very difficult time. The problem with all of these super-high-tech, incredibly complex solutions that have never been tried before is lead time. Ground-based solar is happening NOW, and costs are becoming very predictable - more predictable than another fossil fuel plant. It’s also the cheapest source of energy today, and battery costs are scaling and dropping to match. If it takes just ten years to get space-based solar started - and that’s aggressive - ground-based solar will have more or less wiped out coal and a lot of natural gas by then, on cost alone. At which point, what does space solar have to offer, other than cost, complexity, and massive risk?
When did the interview at the 8 minute mark happen? He says we have 8 years for "tripling." We have only 6 years. 6 years from today is 11/21/2029. This ambition seems unrealistic when countries are unwilling to spend their trillions on green energy.
Still your pointless comment does add to the stats which will ensure even more people will see this. In fact it's probably why TH-cam suggested it for me. Ironic isn't it?

all energy-producing machinery must be fabricated from materials extracted from the earth. No energy system, in short, is actually “renewable,” since all machines require the continual mining and processing of millions of tons of primary materials and the disposal of hardware that inevitably wears out. Compared with hydrocarbons, green machines entail, on average, a 10-fold increase in the quantities of materials extracted and processed to produce the same amount of energy. For a snapshot of what all this points to regarding the total materials footprint of the green energy path, consider the supply chain for an electric car battery. A single battery providing a useful driving range weighs about 1,000 pounds. Providing the refined minerals needed to fabricate a single EV battery requires the mining, moving, and processing of more than 500,000 pounds of materials somewhere on the planet . That’s 20 times more than the 25,000 pounds of petroleum that an internal combustion engine uses over the life of a car. Among the material realities of green energy: Building wind turbines and solar panels to generate electricity, as well as batteries to fuel electric vehicles, requires, on average, more than 10 times the quantity of materials, compared with building machines using hydrocarbons to deliver the same amount of energy to society. A single electric car contains more cobalt than 1,000 smartphone batteries; the blades on a single wind turbine have more plastic than 5 million smartphones; and a solar array that can power one data center uses more glass than 50 million phones. Replacing hydrocarbons with green machines under current plans-never mind aspirations for far greater expansion-will vastly increase the mining of various critical minerals around the world. For example, a single electric car battery weighing 1,000 pounds requires extracting and processing some 500,000 pounds of materials. Averaged over a battery’s life, each mile of driving an electric car “consumes” five pounds of earth. Using an internal combustion engine consumes about 0.2 pounds of liquids per mile. Oil, natural gas, and coal are needed to produce the concrete, steel, plastics, and purified minerals used to build green machines. The energy equivalent of 100 barrels of oil is used in the processes to fabricate a single battery that can store the equivalent of one barrel of oil. By 2050, with current plans, the quantity of worn-out solar panels-much of it nonrecyclable-will constitute double the tonnage of all today’s global plastic waste, along with over 3 million tons per year of unrecyclable plastics from worn-out wind turbine blades. By 2030, more than 10 million tons per year of batteries will become garbage. The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium. With the world's leading country in production of lithium being Chile, the lithium mines are in rural areas with an extremely diverse ecosystem. In Chile’s Salar de Atacama, one of the driest places on earth, about 65% of the water is used to mine lithium; leaving many of the local farmers and members of the community to find water elsewhere. Along with physical implications on the environment, working conditions can violate the standards of sustainable development goals. Additionally, it is common for locals to be in conflict with the surrounding lithium mines. There have been many accounts of dead animals and ruined farms in the surrounding areas of many of these mines. In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dead fish and large animals floating down some of the rivers near the Tibetan mines. After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even years. Lithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. As a result, some jurisdictions require lithium-ion batteries to be recycled. In spite of the environmental cost of improper disposal of lithium-ion batteries, the rate of recycling is still relatively low, as recycling processes remain costly and immature. More than 400 million batteries are used throughout the country, with only 5% being recycled, resulting in 8000 tonnes ending up in landfill. Creating the lithium-ion battery pack is also more environmentally harmful than the manufacturing process for an average petrol-powered car.
Nice comment with tons of informations (not like most comments here), but sadly no sources. Like you mention it, it's obviously not an easy task to save us from our misery, but doing nothing about it doesn't seem to cut it either, right? It's really not as easy as they seem to put it, like in this video, which is sad tbh. But we have to continue our search for alternatives or otherwise we will lose no matter what. There are each year some great discoveries being made which could maybe change our future for the better. Science is trying to look for new methods to improve production and cost efficiency of those electrical devices or even look for other energy sources, obviously not an easy task. What I'm really looking forward to is nuclear fussion as a potential power source. Let's hope the people working on ITER will change the game. Although this project will take a lot of time and will not immediately change our current situation, yet it's still something to look forward to in my and many other people's opinions. There are still many discoveries to be made in the production of energy from renewable sources. It's not that long ago that we started to invest more time and money in this research field, so who knows what we'll find. Anyway, I myself am obviously no expert and I don't want to pretend to be, but like you I believe there are many issues with some of the solutions presented in this video (and many others). And it's disappointing that those issues are not always talked about and how to remedy those problems. Sorry for my imperfect english, I'm not a native speaker, so hopefully, my comment is understandable

If renewables are going to go down the same track as Australia, you should consider that the Australian taxpayer must foot the bill for compounded inflation and cost of living pressures to fund the $1.2 trillion renewable program because of curtailment caused by congestion and budget blow out that requires farmland equivalent to 10 Tasmania’s. At present Renewables have zero hope of meeting the net zero target because of their inability to meet firming requirements, but the real underlying reason why renewables, particularly wind and solar farms are being pushed so hard is because renewables qualify for carbon offsets which allows polluting industries to offset their carbon pollution activities which is the driving force behind climate change but ironically there is also the expectation that the taxpayer will have a feel-good feeling believing that renewables are saving the planet. There is an alternative. Solar Hydrogen Energy Recovery Gas Turbine. 301Kwh (equal to 46/6.6Kw home solar installations) of solar energy collected from the sun’s nuclear fusion at atmospheric temperature is sufficient for electrolysis obtained from 1/3 of the water volume of an Olympic swimming pool that is recycled by steam reforming to produce 24 hours of Hydrogen gas contained within a 14 cubic meter space compressed between 350-700 bar to enable the start-up sequence of a hydrogen Gas turbine that in turn enables the synchronizing of its Variable Frequency Generator to maintain equilibrium of compressed hydrogen gas to continually fuel the turbine. Oxygen produced from the electrolyzing process is also used as a fuel saving precooled engine catalyst to bring online the turbines energy recovery system and sustain a variably regulated base load power supply to service grid energy demand. The operational variability of the turbine manages both grid inertia, and mis matched frequency while generating a capacity energy range between 86 - 330Mw with optional co-generated steam capacity up to 700Mw of electrical energy on a 24/7/365-day basis. The power generating turbine has three operational parts, 3m in diameter 5.5m long and weighs 6 tons. Installation cost $36.5 -49.5 million, requires an operational footprint area the size of a football field, noise level is 60dbl at 60m, incorporates direct air capture of CO2 at 1,400 Kg/sec and includes a 14-year maintenance free, end of life decommissioning or optional refurbishment program. Sixty-five carbon and pollution free, shovel ready, off the shelf technology that combines solar nuclear fusion with modern aerospace propulsion and existing nuclear and coal fired steam technology to generate a total of 21,450 Mw can be retrofitting to any of the 120 Hydro-electric schemes placed at existing grid conversion points would provide Australia's 26 million population its entire energy needs covering a combined operational area of 33 hectares for a 2023 total cost between $2.4-3.3 billion. Construction period is 3 to 5 years, meet net zero energy target twenty years earlier and makes wind and solar farms including hydro, gas and nuclear energy production redundant.
The entire country of Portugal ran solely on renewable energy for six days in a row in November 2023.
Portugal produced 1102 GWh of renewable energy from wind, hydropower and sun, surpassing its demand of 840 GWh, which allowed it to even export electricity to Spain. It’s a record.
About 60% of Portugal’s energy comes from renewable sources today and is expected to run 100% on renewables before 2045.
Amazing job
Resizer,
hydro power is significant in Portuigal, but also quote, "It doesn’t mean fossil fuel plants weren’t operating"
The reason fo that is renewables' defficiency in critical crite ria for a stable grid supply.
You cannot run a grid on asynchronous renewables alone.
@@iareid8255 That means nothing. The energy was there. The actual consumption energy. I swear to god I always come to videos on renewable energies and there's people hellbent on invalidating any good that is being done. Every time.
Jean,
grid supply needs a specific type of generator, renewables simply do not meet the requirements. They are a dead end and just make electricity more unreliable, more unstable and much more expensive.
Hydro is the only renewable that does0 meet those criteria.
You cannot go against the physical constraints and no amount of tecnical improvement of renewables will overcome their deficiencies. Persisting is s just ignoring reality.
False hope. Because one country can do it does not mean a majority can...This is an emetgency. Face up to it, do not hide & cover your eyes.
The legacy of these abandoned wells must include following the money of the original companies and investors.
They took the money and ran. Part of investing is compliance with EPA and local laws.

Shame on BBC for spreading Delta Airlines' greenwashing. Global aviation represents 2.4% of global anthropogenic CO2 emissions, but roughly 3.7% of anthropogenic radiative forcing in 2018 came from aviation, and aviation emissions are growing 5% per year. Sostainable Aviation Fuel (SAF) is not a real solution. It may have net zero CO2 emissions, but Lee et al (2021) estimates that global aviation in 2018 had a radiative forcing of 100.9 mW/m2, of which 57.4 mW/m2 was from contrail cirrus clouds, 34.3 mW/m2 from CO2, 17.5 mW/m2 from NOx, 2.0 mW/m2 from stratospheric water and 0.94 from soot. In other words, SAF will only solve a third of the problem, but does nothing to address the other two thirds of the problem.
Hydrogen planes are potentially worse than today's planes, because hydrogen planes will emit even more water vapor, leading to more contrails and more cirrus cloud formation, plus hydrogen tanks are high problematic from an engineering point of view. The only real solution is battery electric planes and VTOLs for short distance flights and airships and hybrid airplanes for long distance flights. Another option is switching more travel to electric high-speed trains or hyperloops. Hybrid airplanes can switch to their electric motors when passing through atmospheric conditions where cirrus cloud formation is likely.
Until electric and hybrid planes are developed, the only solution is for planes to try to fly around areas in the atmosphere where cirrus cloud formation is likely, and the BBC should have asked Delta whether it would spend the extra money in fuel and incur the disruption of flight time schedules to do that. It was very poor journalism by the BBC to not understand the science and to not ask Delta the relevant questions, rather than letting the airline spew its greenwashing nonsense about SAFs.
The methane from fossil fuel sources has a GWP-20 (global warming potential over 20 years) of 82.5 and a GWP-100 of 29.8 (IPCC AR6 WGI, 2021), meaning that 1 gram of methane has the same greenhouse warming effect as 82.5 grams of CO2 over 20 years or 29.8 grams of CO2 over 100 years. which is a lot more than "a greenhouse gas several times more potent than CO2", as this video said at 02:02. Since methane lasts an average of 12 years in the atmosphere (technically, its perturbation time), it has a higher impact in the short term.
You claim that electric planes are what's needed but the data on electric cars suggests that evs are worse than ICE vehicles for the environment, when taking into account everything including manufacturing, sourcing energy, road maintenance, product lifetime, and recycling of finished product.
In my area a old pipe line was cut and since nothing seemed to be coming out they simply burried the cut pipe next to the house they were building. Of course a house with the family in it blewup killing the family. Developers are still resisting regulations restriting building on top of old oil fields.
@@sophiadaly4712 Firestone, Colorado, USA. What's weird people go nuts when oil companies want to drill anywhere near neighborhoods but developers build houses with working oil fields in them and in Firestone right over an working oil field with working under ground gas lines. Like, often these lines in old fields do not have allot of gas coming through them and this methane does not have a smell so cutting a pipe does not seem like a big deal. In the Firestone case the contractor simply cut the pipe and filled in the foundation hole. Again, no smell because it is pure methane so the relatively new house blew up killing a family.
@@sophiadaly4712 Yeah, but try to get laws and regulations pasted with so many politicians in the pockets of the developers.
There is a difference between renewable energy and emission-free energy. Bio-fuel emits CO2 and other bad stuff. We need to transition to 100% emission-free, basically solar, wind, and batteries (SWB). When I got going in climate change, renewable sounded great. In fact, I founded a group called Renewable Taos. As time went on and we made local progress, we realized that we really need to focus on emission-free. That is the only proper focus to avert catastrophic climate change. It's a transition, so bio-fuels have some reason. But, they are actually very dirty. SWB is the actual solution. Cooking oil and ethanol are actually bad sources of energy.
Thank you for sharing your knowledge about renewable energy. I completely agree with your focus on emission-free energy sources like solar, wind, and batteries. Speaking of batteries, have you heard of the Segway Portable PowerStation Cube Series? It's a versatile powerhouse with a massive capacity, powerful output, and fast recharging time. It's perfect for outdoor enthusiasts and RV lovers looking for reliable power backup solutions.
22:00 CO2 is not " bad stuff ".IT is green plant food used in natural chemical process ( photosynthesis) which emits oxygen. Do you know how important that is?There have been times in earths atmospheric history when the proportion of CO2 to other atmospheric gases has been higher than it is now ( now the proportion is a meagre 0.004 %) - recently some supposed renewable energy savvy Congress members had no idea of the proportion and made wild stabs ( when asked )of 6% up to 8%.These are people making policy to reduce CO2 emissions!!! Just another thing to zealots playing God with earths atmosphere.Battery storage.Batteries go flat,can be recharged,but not indefinitely, contain dangerous chemicals and take up space.When useless ( after not very long relatively [ compared to nuclear ],how are you going to dispose of them? Landfill? Ugly, much like turbine blades. Landfill batteries will eventually leak to ruin soil and groundwater, then to rivers and finally the oceans.I won't alarm you any further but this whole renewable energy phobia refuses to entertain the drastic consequences that will follow the construction of the " planet utopia ".@user-hh6ex9md4w

What impressed me most is that Ecosia brings all of humanity more forward than what we had in 40 years.
Pity the latest figures say we've hit 1.54 this year having hit 1.5 for periods over earlier years.
Most notable this year was the size of the jump, that the oceans around el nino don't look like they normally do which is to say instead of looking cooler they look hotter.
The latest predictions pointout we're adding renewable on top of existing fossil fuel. Renewable is being used to meet new demand not replace old sources.
The best predictions say 1.7 by 2030 and 2 degrees within 15 years or by 2038 and these maybe conservative as tipping points have been reached and the tipping we were warned of has occurred.
The huge loss of albedo from missing ice means massive ocean warming. Boreal forests are converting themselves to tundra, temperate and tropical forests to grasslands in massive wildfires because we've taken too long. The roller coaster is moving and now natural processes will multiply the effects of the emissions we have failed to reduce.
Climate zones are determined by latitude, altitude, topography and wind and ocean currents driven by temperature differentials.
We've shifted those currents, slowed them and induced more, slower moving and larger oscillations in the jetstream.
This means faster more severe, longer lasting droughts, longer cold snaps with heavier precipitation causing flooding and record snows.
Our infrastructure built for one climate is going to face extremes and frequencies it wasn't designed for. Our crops and the biomes they evolved in will nolonger match the climates they are planted in. Fruit trees will set leaves instead of flowers due to warm winters, grain will rot in floods and prematurely die and dry off in heatwaves, continuing to push up world food prices, while leaving growing numbers hungry.
Topsoil will be eroded in floods and blown away as dust at alarming rates.
This bbc feel good is talking about the solutions to yesterdays problems, that were not able to be adequately implemented on time.

Well the new demand could be met with fossil fuels instead, so it’s a good thing it’s not happening. And population will start decreasing soon, the energy demand will go down, so at that point the more expensive plants, the fossil ones, will be shut down first.
@@deaththekid3998 or we find new ways to use the energy as we have in the past, like data centers. Plus the plans of opec aren't to supply the rest of the world with renewable dependent infrastructure but cheap fossil fuel cars etc. Waiting for the predicted population decline will be to long as natural forcing from tipping points passed will have kicked in.
Renewables are dependent on finite resources and have a limited lifespan, it's our energy demands that have to drop. There's a reason the richest people in the richest countries have the biggest footprint. Our population could half but our footprints could increase 100 fold and still not satisfy the growing demand.
Top stuff - great that you managed to be positive for almost half an hour. That's a refreshing change in this sphere 👏👏👏
So the first part is an add to why we should stop drilling, thanks
It's not new drilling causing the problem but old drilling and pipes where developers build on top of these old fields. Developers have pushed to prevent regulation's where they can build. Often developers can get abandoned oil drilling fields cheap and clean off the surface equipment and have a place to build without the people they sell to ever knowing the history of the land to which their buildings are built on.
@@stanleytolle416 it all starts with drilling and indeed already before anything gets to the end user, the pollution already starts through leaks, energy use, cobalt use and so on.
@@flemlion13 this drilling is often in the middle of nowhere. Like the Firestone case was originally on a desolate hillside not even good for cattle grazing. Fifty years before oil drilling took place. Often mineral rights and surface rights are all mixed up. Like oil and coal companies have rights to extract under ones house or they have done it. Uncapped wells, coal mines, underground fires are all over the place with no mapping. Of course developers want as few regulation's as possible. Surface soil testing is required due to expanding soil, another story, but history of land use is not. A little wild wild West here.
Thanks Carl. My students were inspired by these innovations. Way to go BBC.
question is can bbc and gang be satisfied with less profitable renewable energy?
What?
In his book Rethinking Humanity, Tony Seba along with James Arbib, the founders of Rethink X, say that not only is ditching fossil fuels possible but economical. They say that the transition to solar, wind, and batteries will happen for economic reasons meaning that in 10 years time, most fossil fuel projects will become stranded assets. It’s worth a read
Their new book Bighter is a great read, it is a real positive but grounded explanation of current state of affairs and the future. And it is bright, brighter than we think:) Well if it all works out:P

This is what part of science should be for.
My honest question: Do we have enough raw materials (also including recycling) to make the energy transition ?
I am on with renewable and EV, but it's my biggest concern :/
Having completed an Open University course on renewables, I believe there are plenty of existing sources with more to be discovered. They really can power the world. Wind, solar and hydro already supply over 40% of UK electricity for much of the time. Coal is zero for most of the time thankfully. Its 11.25 am and just now renewables were supplying 54.8% of demand. Fossil fuels (gas) 14%. You can get up to date info from National Grid: Live. BTW the course isn't to degree level but it is one of their free one.
"You want coal? We own the mines."
"You want oil? Well, we own the fields."
"You want nuclear? We own the uranium."
"You want solar and wind? Well, we own the- oh, erm... Solar and wind just isn't feasible, you see?"
Does anyone else think that Ecosia could potentially reshape the landscape as we know it? The long-term implications could be profound.
For the metane emission, Dairy/beef industries should have been mention since they are the greatest emitors by far.
There is a type of seaweed that eliminates the vast majority of methane emissions from cattle. Very little is needed in a cow's diet to have this effect at low cost. A regulation to require this seaweed to stop bovine methane emissions would be very cheap to implement and have an enormous effect. Not surprisingly the beef and dairy industries do everything they can to block such regulations from being passed and they won't self-regulate their methane emissions.
The sea ,tropical rainforests ,wetlands and termites are all larger methane emitters than beef and dairy farming .by far !

WIND for example. What they TELL YOU wind farms "produce" in terms of energy, is based on "name plate capacity." This is what a turbine will produce at maximum power. ie. when the wind strength is JUST RIGHT over a 24 HOUR period. 😄
HOWEVER 🙁
From proven data, wind farms rarely produce even 20% of what is claimed, due to either downtime for maintenance or TOO MUCH/TOO LITTLE wind. Hence gas fired power stations are still kept on stand-by ( at great extra cost ) to fill the gap when wind & solar cannot cope with demand.
We are saddling our kids and grand kids with TRILLIONS in debt, for a system that DOES NOT WORK. 😡

I don't know about saying Burlington is 100% renewable, this only seems to refer to the electricity grid, not transport, also not city heating according to one website, whatever that means exactly, might be a lot in their climate. Transport is usually around 30% of emissions. If they had gotten everyone to buy an electric car they would have mentioned that somewhere surely, this would cut transport emissions to about half, 15%, still perhaps not enough.
It is common to talk about being 100% renewable without counting transport, this seems rather self-deluding avoiding addressing the probable need for walkable, "15 minute", cities or communities bypassing transport where possible.
Having worked in the clean energy and renewables space for many years, I’ve seen a lot of misinformation touted in these interviews. Renewables are an intermittent source of energy. When comparing the price of renewables to other sources like baseload nuclear or fossil fuel energy generators, you need to look at the total system costs. These system costs include the transmission infrastructure needed to transport energy to consumers, and also the enormous amount of storage that’s needed when the renewables aren’t generating anything. If you include the cost of all this extra infrastructure, it is much higher than the cost consumers currently paid for their existing baseload generators. Moreover, the area footprint for renewable generation is much larger and conventional based generators. We need to ask ourselves where we’re going to get all the necessary minerals to realise these nets zero fantasies by governments where are we going to get a cobalt, nickel vanadium, silver?? There aren’t enough known reserves for these minerals at the present time? All these discussions about sustainable aviation, fuels are fanciful. Here, again. You need to look at the total system costs, which include harvesting all the biomass and organic resources, transport, costs and refining costs. How much landmass are we going to have to commit for these biomass fuels? And is that the most sustainable outcome for this biomass?
Solar is glorious, solar shows you care.
The new tech can make a difference if power generation is a human right and we can let middle and lower incomes pool their money together and fund a windmill or something literally giving the power to the people.

Wind and solar energy demands a huge quantities of non renewable materials.
Pledge or Tax....Choice or Decision...The Carrot or The Stick...ProActive or ReActive approach....The Time is in our Hands. There's only 1 Earth
The Royal Society recommend the UK should have 100TWh of energy storage (it's currently 39.3 GWh from 4 pumped storage facilities). That's over a 2,500 fold increase. That means building 10,000 pumped storage facilities or 400 every year. A typical pumped storage facility has a 300 to 400m dam built to hold back 10 million cubic metres of water, with a fall to the turbines below of about 400 metres.
That's at the same time as increasing wind power generation from 75TWh (in 2020) to 665TWh (in 2050 - these are UK National Grid figures). That's around 100,000 giant wind turbines. And by the time you get to 2050, the 4,000 wind turbines you needed to install in 2025 would have reached the end of their working lives and will need to be buried in landfill, and replaced with another 4,000. It's all impossible and absurd.
The cabling and additional structures to connect all this together will essentially require the UK consuming all of the current global supply of copper and other rare metals for the next 25 years. The cost will be unaffordable and the skilled manpower levels unattainable. And that is just to eliminate the less than 1% of the global CO2 emissions that the UK is responsible for. So times that by 100 for the whole Earth going Net Zero. Good luck with that.
If 100 countries say... "but we are only 1%" and do nothing, then nothing will change.

Renewable cannot solve the problem alone. The proper mix of energy sources for co2 reduction is made by nuclear for the baseline, renewable and gas where the last two are not available.
nuclear is already more expensive than green energies. also with nuclear you always get privatised profits and socialised costs in the end
@@hunterspeak4370 this is not true. Renewable cost per MWh is comparable to the nuclear cost per MWh for plants built in 5-6 years, with the advantages of scalability and low impact
Wrong it is happening battery grid etc
@@theodoredesmarais4219the battery cost is unbearable!!
No. The overnight costs of a gen 3 nuclear plants is €6B, which makes the price per MWh competitive to gas plants. The financial costs depends on the government decision to subsidize the construction of the nuclear plants, like they do for the renewables.
What does upstate New York mean ? State of New York rather than the city of New York? Upstate= in the mountains? or upstate= in the north of the state ?
Mirror concentrators are not as cost effective as solar panels
It can store for 8 hours. So are solar panels with energy storage still cheaper?
Yes,it's obvious.
We really have to ponder this: why do the UK citizens pay a few times MORE than most people in the world when the renewables can now be even cheaper than energy from fossil fuels? To put it into perspective, in some Asian countries that only use natural gas to generate electricity, they pay only 10-12p per kwh (without standing charge) while we are paying bloody 27p per kwh + 35-40p standing charge per day! How could ours be that expensive?
There must be something wrong with our system! Our government must fix this or everyone in the UK will continue to suffer badly, both socially and economically.
Renewables are more expensive when you take into account all the costs necessary to deliver a stable electricity supply (power lines to transport electricity from thousands of disparate solar and wind farms far from where the electricity is used, energy storage because renewables are intermittent and a stable electricity supply is needed, grid balancing to respond to changes in generation, the cost of maintaining stand -by natural gas power plants to cover renewables when they fall short, plus all the maintenance on the above plus all the interest cost on the vast amount of infrastructure that needs to be built to deliver all of this - much of the renewables were built with near zero interest rates).
Also by inspection we know it is more expensive because if it were the cheapest it would not need subsidy and the UK would have high energy industries setting up on its east coast to take advantage or the wind energy from the north sea.. but in reality renewables are given subsidies, gas power stations are taxed, and high Energy industry is leaving the UK.
So when someone says renewables are cheapest they are ignorant or gaslighting.
Hopefully there will be more technologies that emerge that are more practicable than current wind and solar.
DIGITAL ENERGY SERVICES as well as extensive services up to and including operation and maintenance services for PV power plants round off the SMART CONNECTED RANGE.
15:25 what is she talking about!? 90% from jet fuel? Where does she has such huge value from? I have found only around 3% of pollution from airplanes?
Burlington might have 100% renewable energy, but it is far from zero carbon emissions. In fact with one third of its electricity coming from burning biomass, it is in fact a big emitter of greenhouse gases.
That carbon was fixed from the atmosphere when the plants were growing, which was very recently.
Not always recent. The UK is importing woodchips from Canada. Some of this is from old forests which are supposed to be protected. Also it doesn't make sense to cut the wood, trans port to the coast then send it across the Atlantic, then transport to the Drax power station near Selby in Yorkshire - some distance from the coastal port.@@biggusdoggus
@@ralpharmsby8040 it rather depends on what the exact criteria is for recent, but the age of wood biomass is several orders of magnitude less than coal, for example. I agree that transporting wood such a long way does not make sense. I have not read a LCA for the case you mention, but the OP was about Burlington, and the plant there claim to primarily source biomass from the local area.
Great job,sealing old oil and gas wells 👌👍
@josemercado3063 look like impossible task to complete.No way they can seal even small percentage of those old wells.

Good Morning, Energy Star
Good morning, bright Energy Star,
You rise with power, near and far.
Awake the day, your light so clear,
Fueling dreams, chasing fear.
Your beams ignite the endless sky,
With warmth that makes the spirits fly.
Each spark you give, we come alive,
On currents bold, we dare to thrive.
The fields you touch begin to glow,
With winds that whisper, rivers flow.
In solar streams and waves of air,
You light the path, beyond compare.
We greet you now with open heart,
A shining guide, a brand-new start.
Good morning, Star, let’s chase the flame,
Together we’ll ignite the name.
The battery is better and better. Electric motors is the best for the good of our mother earth.
Still waiting for the space-based solar panel technology
By the time we get that, ground-based solar will have already won.
@@davestagner Ground-based solar panels take too much space and aren't as effective as the space-based one
@@containedhurricane How much space do ground receivers for space-based solar take? But seriously, “too much space” isn’t a defensible argument. There’s plenty of rooftops and parking lots, in addition to wide open spaces. Ultimately, though, it’d take 20 years to get space-based solar working at meaningful scale, IF we started now with an all-in effort. Ground-based solar is doubling every 2-3 years, in large part because you don’t need billions of dollars and tremendous engineering efforts and international cooperation to put up a solar panel. I do not understand the obsession with doing the most technologically difficult and ridiculously expensive approaches to getting rid of fossil fuels, when something simple and cheap is right there in front of our noses.
@@davestagner I bet it will require the space of a desert to match the power gained from a few space-based solar panels. If the space-based ones weren't potentially more lucrative in the long run, the UK scientists wouldn't plan to make them
@@containedhurricane Has a government invested at least a billion dollars into the idea? Is there a timeline? Could they have it in production by 2030? If the answer to any of these is “no”, then it’s going to have a very difficult time. The problem with all of these super-high-tech, incredibly complex solutions that have never been tried before is lead time. Ground-based solar is happening NOW, and costs are becoming very predictable - more predictable than another fossil fuel plant. It’s also the cheapest source of energy today, and battery costs are scaling and dropping to match. If it takes just ten years to get space-based solar started - and that’s aggressive - ground-based solar will have more or less wiped out coal and a lot of natural gas by then, on cost alone. At which point, what does space solar have to offer, other than cost, complexity, and massive risk?
Contamination risks of natural Aquafur systems should always be considered. ❤❤❤❤❤
Why inflation in USA ? Why electric bill in inflation ?
When did the interview at the 8 minute mark happen? He says we have 8 years for "tripling." We have only 6 years. 6 years from today is 11/21/2029. This ambition seems unrealistic when countries are unwilling to spend their trillions on green energy.
No.
Next.
Still your pointless comment does add to the stats which will ensure even more people will see this. In fact it's probably why TH-cam suggested it for me. Ironic isn't it?

all energy-producing machinery must be fabricated from materials extracted from the earth. No energy system, in short, is actually “renewable,” since all machines require the continual mining and processing of millions of tons of primary materials and the disposal of hardware that inevitably wears out. Compared with hydrocarbons, green machines entail, on average, a 10-fold increase in the quantities of materials extracted and processed to produce the same amount of energy. For a snapshot of what all this points to regarding the total materials footprint of the green energy path, consider the supply chain for an electric car battery. A single battery providing a useful driving range weighs about 1,000 pounds. Providing the refined minerals needed to fabricate a single EV battery requires the mining, moving, and processing of more than 500,000 pounds of materials somewhere on the planet . That’s 20 times more than the 25,000 pounds of petroleum that an internal combustion engine uses over the life of a car. Among the material realities of green energy:
Building wind turbines and solar panels to generate electricity, as well as batteries to fuel electric vehicles, requires, on average, more than 10 times the quantity of materials, compared with building machines using hydrocarbons to deliver the same amount of energy to society.
A single electric car contains more cobalt than 1,000 smartphone batteries; the blades on a single wind turbine have more plastic than 5 million smartphones; and a solar array that can power one data center uses more glass than 50 million phones.
Replacing hydrocarbons with green machines under current plans-never mind aspirations for far greater expansion-will vastly increase the mining of various critical minerals around the world. For example, a single electric car battery weighing 1,000 pounds requires extracting and processing some 500,000 pounds of materials. Averaged over a battery’s life, each mile of driving an electric car “consumes” five pounds of earth. Using an internal combustion engine consumes about 0.2 pounds of liquids per mile.
Oil, natural gas, and coal are needed to produce the concrete, steel, plastics, and purified minerals used to build green machines. The energy equivalent of 100 barrels of oil is used in the processes to fabricate a single battery that can store the equivalent of one barrel of oil.
By 2050, with current plans, the quantity of worn-out solar panels-much of it nonrecyclable-will constitute double the tonnage of all today’s global plastic waste, along with over 3 million tons per year of unrecyclable plastics from worn-out wind turbine blades. By 2030, more than 10 million tons per year of batteries will become garbage.
The extraction process of lithium is very resource demanding and specifically uses a lot of water in the extraction process. It is estimated that 500,000 gallons of water is used to mine one metric ton of lithium. With the world's leading country in production of lithium being Chile, the lithium mines are in rural areas with an extremely diverse ecosystem.
In Chile’s Salar de Atacama, one of the driest places on earth, about 65% of the water is used to mine lithium; leaving many of the local farmers and members of the community to find water elsewhere. Along with physical implications on the environment, working conditions can violate the standards of sustainable development goals.
Additionally, it is common for locals to be in conflict with the surrounding lithium mines. There have been many accounts of dead animals and ruined farms in the surrounding areas of many of these mines. In Tagong, a small town in Garzê Tibetan Autonomous Prefecture China, there are records of dead fish and large animals floating down some of the rivers near the Tibetan mines.
After further investigation, researchers found that this may have been caused by leakage of evaporation pools that sit for months and sometimes even years. Lithium-ion batteries contain metals such as cobalt, nickel, and manganese, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. As a result, some jurisdictions require lithium-ion batteries to be recycled. In spite of the environmental cost of improper disposal of lithium-ion batteries, the rate of recycling is still relatively low, as recycling processes remain costly and immature. More than 400 million batteries are used throughout the country, with only 5% being recycled, resulting in 8000 tonnes ending up in landfill.
Creating the lithium-ion battery pack is also more environmentally harmful than the manufacturing process for an average petrol-powered car.
Nice comment with tons of informations (not like most comments here), but sadly no sources.
Like you mention it, it's obviously not an easy task to save us from our misery, but doing nothing about it doesn't seem to cut it either, right? It's really not as easy as they seem to put it, like in this video, which is sad tbh.
But we have to continue our search for alternatives or otherwise we will lose no matter what. There are each year some great discoveries being made which could maybe change our future for the better. Science is trying to look for new methods to improve production and cost efficiency of those electrical devices or even look for other energy sources, obviously not an easy task.
What I'm really looking forward to is nuclear fussion as a potential power source. Let's hope the people working on ITER will change the game. Although this project will take a lot of time and will not immediately change our current situation, yet it's still something to look forward to in my and many other people's opinions.
There are still many discoveries to be made in the production of energy from renewable sources. It's not that long ago that we started to invest more time and money in this research field, so who knows what we'll find.
Anyway, I myself am obviously no expert and I don't want to pretend to be, but like you I believe there are many issues with some of the solutions presented in this video (and many others). And it's disappointing that those issues are not always talked about and how to remedy those problems.
Sorry for my imperfect english, I'm not a native speaker, so hopefully, my comment is understandable

If renewables are going to go down the same track as Australia, you should consider that the Australian taxpayer must foot the bill for compounded inflation and cost of living pressures to fund the $1.2 trillion renewable program because of curtailment caused by congestion and budget blow out that requires farmland equivalent to 10 Tasmania’s.
At present Renewables have zero hope of meeting the net zero target because of their inability to meet firming requirements, but the real underlying reason why renewables, particularly wind and solar farms are being pushed so hard is because renewables qualify for carbon offsets which allows polluting industries to offset their carbon pollution activities which is the driving force behind climate change but ironically there is also the expectation that the taxpayer will have a feel-good feeling believing that renewables are saving the planet.
There is an alternative.
Solar Hydrogen Energy Recovery Gas Turbine.
301Kwh (equal to 46/6.6Kw home solar installations) of solar energy collected from the sun’s nuclear fusion at atmospheric temperature is sufficient for electrolysis obtained from 1/3 of the water volume of an Olympic swimming pool that is recycled by steam reforming to produce 24 hours of Hydrogen gas contained within a 14 cubic meter space compressed between 350-700 bar to enable the start-up sequence of a hydrogen Gas turbine that in turn enables the synchronizing of its Variable Frequency Generator to maintain equilibrium of compressed hydrogen gas to continually fuel the turbine.
Oxygen produced from the electrolyzing process is also used as a fuel saving precooled engine catalyst to bring online the turbines energy recovery system and sustain a variably regulated base load power supply to service grid energy demand.
The operational variability of the turbine manages both grid inertia, and mis matched frequency while generating a capacity energy range between 86 - 330Mw with optional co-generated steam capacity up to 700Mw of electrical energy on a 24/7/365-day basis.
The power generating turbine has three operational parts, 3m in diameter 5.5m long and weighs 6 tons. Installation cost $36.5 -49.5 million, requires an operational footprint area the size of a football field, noise level is 60dbl at 60m, incorporates direct air capture of CO2 at 1,400 Kg/sec and includes a 14-year maintenance free, end of life decommissioning or optional refurbishment program.
Sixty-five carbon and pollution free, shovel ready, off the shelf technology that combines solar nuclear fusion with modern aerospace propulsion and existing nuclear and coal fired steam technology to generate a total of 21,450 Mw can be retrofitting to any of the 120 Hydro-electric schemes placed at existing grid conversion points would provide Australia's 26 million population its entire energy needs covering a combined operational area of 33 hectares for a 2023 total cost between $2.4-3.3 billion. Construction period is 3 to 5 years, meet net zero energy target twenty years earlier and makes wind and solar farms including hydro, gas and nuclear energy production redundant.
