I've mentioned this a few times here, but I work for the world's largest solar panel manufacturer, we alone produce just over 100GW of solar modules/year, and are sold out completely for the next few years, and there are 4 other companies who are building about the same capacity as we are, with a dozen other companies equaling our combined build capacity. In short, the global annual build capacity of solar is 1TW, and growing, every year, which is equivalent to: ~2000 500MW gas power plants, which produce energy at about 1/3 the cost of gas. It's easy to see why there's virtually no new gas power plants being installed in the world, nor will there, and why hundreds are shutting down, every year. Coal is long dead and nuclear is DOA.
@@DGlass-yg8xk I don't know about Germany, but in Australia (where I live) solar is bring the cost down. Our prices are high after years of no government policy and a lack of investment in infrastructure. Thanks to the cheap cost of solar, it's being deployed regardless of gov policy and prices are coming down.
yeah the pannels dad put up when i was a kid are still running although we got new ones also the capacity on those 90s pannels where never amazing to start with and they did reduce a bit over time but batterys we have had to replace a couple of times despite being carefull on the cycles
We had the power out for over 2 days after a storm funny how the nay sayers in my street asked to put there perishables in our garage fridge and charge laptops and other devices. From our Solar, battery and EV. Also my wife left one of our cars an EV at her mothers home to partly power her house for a day Yes we still own one ICE car for now,. Hey Sam keep reporting stay well ,safe and brave.
It makes a lot more sense for developing countries to go to solar rather than build coal plants or whatever, especially places poor enough that they don’t have an existing power grid. Microgrids can be made with very little money and no connections to a larger grid. There’s an assumption that places just electrifying now must go through the same centralized fossil fuel grid pattern as wealthier countries, but it doesn’t actually make sense cost-wise, not anymore.
@ I’m convinced that this, at least as much as climate if not more so, is why China is pushing SO hard to move to renewable energy and EVs. They have very little petroleum of their own, which makes them dependent on middle eastern chaos. And since China doesn’t have the bad imperialist/colonialist habits of the US and Europe, they’d probably be happier with a bunch of independent countries they can trade with, not proxy wars, civil wars, and the occasional US “antiterrorist” action. And the US squanders blood and treasure in the middle east and Africa mostly for the sake of oil. China wants to wash their hands of it. They want their allies to wash their hands of it.
@@davestagnerif you think China does not flex imperialist power you're delusional. Doesn't mean US is better or morally superior, but China absolutely uses their power to get what they want. Belt and road.
I’m gearing up for solar. First I got to re-roof my house by myself. Then I’m going to buy and install my own solar. Right now stocking up on tools and roofing.
The way to go is solar and battery. I installed roof solar and looking for batteries by the end of the year - or smaller battery and a car to power the house at night and go off the grid.
Quite possible in the future when V2H is mainstream. A house battery is still needed to keep things going in case you need to nip down too the local fast charger to cart some energy back to the house.
I agree with the sentiment of most of this. One caveat I'd add about the continued reduction of the cost of solar cells is that they already only represent a small percentage of the total cost of the installed solar system. Hypothetically if tomorrow the cost of solar cells fell to zero, the total cost of installing 10kW of rooftop solar would only fall by about 10%. Hopefully the next leap forward in solar advancement will come from more efficient solar (e.g. tandem cell perovskite) which can achieve the same capacity with fewer solar panels.
Ethiopia banned the import of non-electric vehicles on January 29, 2024. This made Ethiopia the first country to completely prohibit internal combustion engine cars.
@@martinv.352, 88.9% of new passenger vehicles sold in Norway in 2024 were battery electric vehicles (BEVs), so Norway has not "already finished the transformation". Norway has a goal of 100% electric in 2025, but it will probably be around 95%, and it will probably take another 5 years to move the heavy vehicle market to 100% electric. Only 26% of Norway's auto fleet is electric, so it will take a while to replace the existing ICE cars.
No moving parts energy production, low maintenance, long service life, recyclable materials make up, useable land for animals and crops, low pollution, no noise, pays for itself in a short time. WIN WIN WIN WIN WIN
I've had solar cell panels on my boats since 1981 to charge the batteries. No problems at all. Even in cloudy weather it works fine. It helps a lot that in Norway the sun never sets properly in the summer months, just for a couple of hours and it doesn't get dark. The same goes for leasure houses and cottages. And the panels cost much less than a few years ago and last "forever".
Sam, the counter argument is that while renewables are cheap they are not as profitable as fossil fuel installations so companies will continue to invest in them and push governments to back them up. Can you make a video about that? Thanks! 😊
Yes, utility in my area, Ca Bay Area, charges customers for their grid “improvements”. So if a gas plant costs more they will damn well build a gas plant. So they can charge us more.
It’s a bit distressing to hear naysayers point out that the sun doesn’t shine at night and that it’s not always windy. Not because it’s true, but because can they really think that anybody has to be told that? The fact that so much work has gone into energy storage (and not just batteries, also hydroelectric, gravity batteries, heat storage etc) implies that, yes, we actually did know that, and no, we are not waiting for the sun to stop setting.
Actually, the sun ALWAYS shines on a goodly portion of Earth's surface. If HVDC lines could efficiently transport energy east and west around the globe, and south to north from tropical region to northern countries, then no storage at all would be needed! It is technically feasible. OBVIOUSLY, going all the way in this direction would be financially excessive. But so is storage without such interconnections! So, the answer lies in a cost optimum between the two (plus a few other ways to address wind and solar intermittence).
Always funny when somebody comes along with "It was cloudy today, if I had solar it wouldn't have produced anything!", as if they're the first amazing genius to have figured this out. Also it's not even true, anyway. Some people on Will Prowse's forum are getting power from moonlight! (not a lot, mind you)
In Southern California, a rooftop solar system pays for itself in about five years. After that, the energy continues to flow. Of course it is economical to put in solar there. It costs less than one fifth the price of the energy from the utility.
You are a consumer. That's all upside for you. Think what it looks like for an investor planning to invest a few billion in energy infrastructure. They have the prospect of investing in a project that is easy for competitors to compete with, where turnover is low and where margins are cut to the bone to sell the electricity. Compare this with fossil fuel projects where the barriers to entry are high and the margins are consistently high. This is why, without subsidies, the transition is just not happening as you would expect based on the comparative costs of solar vs fossil fuels. Because investors don't go where costs are low. They go where profits are high.
@@michaelrch That all depends how things are structured. It costs money to build another 1 GW coal or gas plant, it requires fuel and maintenance. It may be cheaper to build a battery and store the excess solar from rooftop solar during the day which you didn't have to pay for and release it as needed.
When cell phones were first invented only doctors could afford them. After a number of years the price did come down . Now people buy phones for kids it’s so affordable
@@jvdm9317 The point is that phones have dropped massively in price. I bought a great one for seventy pounds (eighty dollars or so) and it has been brilliant. For all the functions that phone provides it has actually saved me money. Remember when you needed a calculator, a memo pad, a camera, a diary, etc, etc - in addition to a pretty useless mobile phone? Remember when you could only access the computer at home?
The ULTIMATE in power generation is to have a distributed power grid - it's better for the land AND security. Can't target a power plant if the whole city is providing power. I also really like the idea of having excess electricity - there are plenty of uses for cheap excess only energy - eg run AI datacenters with older less efficient hardware. Have them pause the workload when solar isn't generating. Pump water up a hill to provide hydro power later, crypto mining whatever. Then at night have the systems pause, where you only run the latest most efficient workloads.
Somebody up the road from me has what looks like a 100w panel (though it's really old, it has those circular blue cells, so it might be 50w) laying out on the street, propped up on their flowerpots, and presumably still producing.
How much did those batteries cost? I have built two 8kwh packs that total $3k or so. I would need at least twice this for my meager 1100 sq ft townhouse. I live in a townhome that has limited roof space and in winter I get no sun on my roof. I love solar, but it is not economical for the majority of people. IF batteries were as cheap as solar panels Then no problem. And they might be in a few decades, but right now: no.
how about the genset for winter, you haven't mentioned that, its impossible for you to be off grid and live anything close to a typical grid connected house. In winter you won't have enough solar to run your house never mind charge the batteries.
@@taylorcuthrell4123 I have 10kW system on the roof facing north, a Tesla 13kwh battery with our new house plus a 32amp Tesla Gen 3 charger. All up cost was $31k and expecting to be net credit (saving $2k annual power bill previously plus another $2k saved on my fuel bills for the car). Expecting to pay off the investment in 5-7 years.
@@taylorcuthrell4123Does your electric price fluctuate over the day? Even charging the batteries at night and using them at peak times could save you a packet. Treat any charge from solar as a bonus.
I am visiting Pakistan after a few years, most of my relatives who own their houses have giant solar panels installed on the rooftops with battery backups. From affluent parts of the city to low income parts, I see solar panel mounts on the roofs everywhere. I am amazed by how quickly people have jumped on solar and that's mainly because the Chinese companies have made it affordable.

an acquaintance of mine used to be the CEO of Siemens🇩🇪. His name is Heinrich von Pierer. He blames our green politicians for our energy mess and for the destrucrion of our German industry. Many of our big companies leave Germany for USA, China and other countries with much cheaper energy prices and with less environmental regulations.
Let's acknowledge that Australia presents a best case scenario for solar: very low installation cost even for residential solar. Not easy or impossible to get there in most other regions of the world as the module cost is only part of the cost, the others are labor, permitting, shipping, racking, and fees.
Have you seen the item about China planning to build an orbital solar array that, if it works as planned, will provide more energy than all of the world's oil? Scientists have been talking about this for years but if China decides to do it, the odds are that it will be done!
It won't happen, because terrestrial solar will become so cheap that it won't make financial sense to spend that much money launching solar panels into space.
@@amosbatto3051 Agreed. NIO’s BaaS, when paired with their battery-swapping infrastructure, is like a Swiss Army knife for EV energy needs-versatile, customer-focused, and grid-friendly. Tesla’s buried solar/grid stabilising batteries are more like a power bank for their Supercharger network: essential but less dynamic in serving customer demands directly. Viking won't even entertain the idea that the grid will need stabilising which is fairly weird given his predicted uptake...I think it's an anti-Nio thing lol. 🙂
Question 1: From ore or scrap steel? There is a huge difference Question 2: in what length of time? 1s, 1m, 1hr, 1 day, 1 week, 1 month, or 1 year??? If I know the answers to Q1 and 2... especially Q2, then I can answer you.
@@mikewallace8087 The original question is non-sensical without knowing in how long a time you want that ton of steel produced.... as well as other parameters But let’s give it try: It takes about 4 MWh of electricity to make one ton of steel, using green hydrogen for the reduction (instead of coal) and an electric-arc furnace. A kW of solar panels produce on average about 1.3 MWh in a year… more in Arizona but less in Germany. So, you need about 3 KWp worth of solar panels (i.e. 6-8 panels depending on the models) to produce 1 tonne/year of steel. To know the size of the solar park needed, just multiply by the yearly output you want your steel mill to have! The steel industry is going to migrate from the places where there is (or was historically) iron ore and coal resources, to places where there is iron ore, and plenty of sunshine! That sounds quite a bit like Australia, China or Brazil, doesn't it? Obviously, the production of steel from scrap metal is best done regionally!
The S-Curve is already happening in Brazil. Including homeowners, solar is already the second source of energy after Hydro. If things keep like this, Brazil will only use their dams for generating power at night.
@@markoprusevic9175 I was talking about electricity: 45% hydro, 15% solar and 12% wind. The quick rise of solar and the advent of EV can reduce fossil consumption.
@ depends. Building a dam. Maintaining it. Sediments removal. Destruction of life in waters, death of trees and plants. Destraction of natural flow of rivers etc… there’s a good video here on TH-cam showing how immense that can be. Only run-of-river power plants are harmless
I love this. The people who want to continue with dirty energy want to continue profiting from it. Solar doesn’t have inputs to sell. They can’t figure out how to control access to solar so it’s all hands on deck to attack it. This mentality is playing out right now with AI. Verses AI’s Genius platform is murdering LLMs left and right. Today they came out with stunning results in the Atari 10K challenge. Entrenched power knew what was coming so we got the awkward Stargate press conference yesterday, creating a vacuum in the media verse. The cool thing is Genius is incredibly energy efficient and Verses is working with Volvo now- maybe all of Geely soon?
Solar is the most important where you live but where I live there is no chance solar alone can get us through from late October - late March, we need wind or cheap long term storage...
Yes, indeed! So what? Wind and solar tends to compensate each other's intermittence! No long-term storage is needed... with some exceptions of the northernmost countries and regions.
@ Your 80% share is somewhat exaggerated IMHO, but you are fundamentally correct. A very large part of the world's population would be fine with only solar + storage obviously.
The price of batteries is plummeting, and there's a ton of research being done on making them even better, cheaper and longer-lasting. Not all of that research will come to fruition, of course ("huge groundbreaking game changing batteries" get hyped up by certain youtubers every single week ;) ), but some of it will. Once upon a time they thought the best lightbulb filaments would be Chinese people's hair.
@@st-ex8506 The issue is that it is hard to overbuild for wind. With solar you can build it like 3 times more and it will ensure that even if there is less solar radiation on some days, it can still cover your needs. With wind the difference of when it blows and not can be massive. You can overbuild it 10 times but when there is no wind there is no wind, and when there will be wind unless you have huge next gen longer storage batteries, you will need to heavily curtail it. These challenges will be solved in future but at the moment unfortunately it is an issue in colder climate countries that winter season can be a struggle when using just renewables. Mainly because we do not have massive and cheap longer term storage for wind which is less predictable as solar. Not to mention that it is also hard to overbuild wind as it is now more expensive and a number of people are very much against "them windmills that cause cancer"...
Good that you mentioned the tough stuff that is getting fair participation of consumers. Regulations must transform to enable full consumer energy resource CER participation in the NEM.
About time too. My parents installed a solar water heater panel on the roof in 1983. It was a brand called Elesolar (I think it was Italian). I always wondered as a child, why nobody else had one?
I agree, the more energy that is stored from renewable, all fossil fuel assets will be threatened as a stranded asset and public utility commissions will be forced to lower the price for consumers based off their required revenue formulas.
I work in the solar industry in the Global South and the switch to renewables is going much faster, because the advantages of not having to invest as much in centralized infrastructure is massive and the irradiance obviously is much higher. If it's possible to include storage at a lower price, they will surpass 'the West' in adoption as well as economic growth.
Solar needs 0.1 gram of silver per watt that is 100,000 metric tons of silver per terrawatt. China want to make another 8 TWs of solar but there is not enough silver left in available supply
Right on. Solar has no moving parts, a huge advantage over wind in my opinion (practically zero maintenance cost!). Any other source, old or new, does not come close in initial build cost and maintenance cost.
People tend to think they're complementary because wind power is also on a decreasing cost curve (and wind blows at night). But yeah, I think solar will be the bigger part globally, because it's hard to beat no moving parts. Unless you're in Ireland, where it's always very windy and very overcast.
its not just renewable energy that is wasted so is 1/2 the fossil fuel power. battery's can not only be used to improve that efficiency they can be used like we use water revivors in plumbing to keep the pressure up on lines allowing more more efficient distribution of power along existing network, if we place them strategically like water revivors (for eg in the residential clusters the power needs to be sent to)
Not a fan of roof top solar, I have a wood roof. For my current solar I used a ductile iron pipe with up to six panels mounted and a stone dead man foundation to take wind loads. As I have black locust on the property (northeastern US), I am considering the replacement of ductile Iron with Black Locust and a black cherry frame. I think it should probally last the lifetime of panels. I've started growing white cedar and incense cedar (plan on planting red cedar) for future structures.
Amazing ❤. Like written in another comment "most important video Sam." I hope this is really correct. Sounds like it is. This is consistent with Elon Musk presentation and calculations of Tesla. I hope Elon Musk will push Trump to adopt this as well, which is contrary to his statement of "drill baby drill"
Prices for electricity in Germany are sky rocketing. We pay on average aprox. 35 Cent/KWh. There’s so many additional costs and taxes included - mostly needed to finance the renewables and the highly over dimensioned grid. It has to be 4 times larger now because we don’t have regional NPPs anymore. 🤦♀️
I fully agree. German developement companies have plans for 164 GWh in the next 2 years. Big money is comming into town, relieving local taxpayers. The future will be bright.
big battery here between denmark and germany would pay off rather quick. price on power broke records countless times this winter and still powerprice go to 0 other days
Having a battery for your house almost never pays off. The money you save vs what a solar roof installation and the cost for the storage battery is, it takes aprox. 20 years to pay off. And that only if you stay at home 365 days a year. I live in southern Germany and we are every year in August one month away. if you take that into account, it never pays off.. you need to replace the battery after 20 years the latest..
We just bought an EV with a bidirectional battery in it (2025 Chevy Equinox). Am in discussions with a local electrical company (which specializes in renewables work) to get the charging system installed so that the EV will act as battery storage for the house in event of power outages. Our solar arrays presently provide about 62% of the electric needed to run the (all electric) house. I've been considering adding another array--that'll be a trickier install (hence more costly but hey, it's only money) and that'd get us up close to 100%.
primary energy production in Germany is still ca. 80% from non renewable energy. Only electricity production ist aprox 50% by renewables. Including imported electricity mainly produced by coal and nuclear power.
I have a 100 KWp Photovoltaik. In Summer there‘s a lot of electricity production, at least during the day. During the night there’s no production 😅 and in winter there’s as well almost no electricity production. So we need 100% backup for PV
100Kw? Do you realise how big that is, or are just lying in some lame attempt to discredit solar? My old job had 13Kw and the panels were bigger than the floor area of my flat. Where are you putting this 100Kw? Do you own a whole field? What are you doing with the rest, because at peak production that's far more than enough to run every appliance in a house non-stop. "😅" indeed.
@ ?!? It’s not on the roof of my house. although it’s on the roofs of several farming buildings in eastern Germany. The usual size of such power plants is up to 750 KWp. Because that’s the maximum size for a better tax incentive. 😜😁 I only own a part of it with two inverters. Which is in my case a bit below 100 KWp. It’s 100% going into the grid.
Just two technologies are capable of solving the energy over the next 20 years…. Solar panels, both commercial and domestic, and V2G. Once the EV revolution is “complete” (once ICE vehicles are reduced to enthusiasts only) the spare battery capacity of collective EVs plugged into the grid at any given time, will be massive.
You need oil to mine the materials for the solar. You need oil to transport and install solar. Solar is the way, but we have need for decades of oil production to build solar out globally. Not all geographies are as suitable to solar as Australia is. In Australia, no doubt solar can do it all. Elsewhere not quite yet.
Not sure how many other people have experienced this in Australia. Had a friend who told us yesterday that the solar company they contacted, told them it is not worthwhile installing solar panels after seeing their power bills of the last 12 months ($170/month). Not sure if the solar company got it. Our friend does actually want home battery as part of the system as well. I cant see any reason why the solar company has said what they have said. Their roof gets enough sun exposure. Anyways, i have passed on your installer Resinc’s details to our friend in Melbourne
The government should finance batteries for every suburb, or for every home (whichever is cheaper). And every house that is newly built must have enough quality solar panels to power it. That is the cheapest way to rapidly transform the grid to solar energy.
Nuclear electricity economics in the UK : Hinckley C has a strike price of GBP190 per MWh. Eg 19p per KWh. British consumers charge their EVs at night paying 7.5p per KWh night rate. So the first question for nuclear fans is : who pays the 12p subsidy per KWh to fund their expensive nuclear reactor ?
1. question: why is it nowadays so expensive to build new NPPs? Might it be due to way to Much and too high regulations? That constant chance during construction period..? 🤔 2. question/ if you add costs for back-ups and/or storage capacities for renewables (and they are as well highly incentivized by tax payers too), is it still cheaper then..? And how long will a NPP run and how long does your PV? How long will battery storage work until it has to be replaced? Probably on double costs then due to inflation etc…?
@volkerr. The nuclear power industry promised "NP will be too cheap to meter" and "meltdown is impossible". They are liars. My solar is not subsidized in NZ. Build your NPP with proper insurance and no public guarantee or subsidy and if you cannot then admit that nuclear power is too expensive to sell in a free market. As for whining about bureaucracy, in the 1970s the coal industry whined that sulphur filters were too expensive but the EPA regulated regardless. We quickly found out that the sulphur filters were much cheaper than the coal power plant whiners had claimed. Safety is important, and if NPP cannot afford safety then we shouldn't build them.
In Germany our installed PV capacity is able to produce more than 100% of electricity needed. When the sun is shining. And only on certain days in high season summer. 😜
By 2035 it is expected that solar panels will have lifespans in excess of 30 years and produce 50% more electricity than the current panels! Solar panels, wind turbines and hydropower supported by Grid storage batteries are certainly the future of electricity generation in Australia and many countries worldwide!
My relatives in the Netherlands, which isn't ideal for solar power, and those living in Pakistan are using solar panel for the same reason: the cost of electricity is very expensive.
In Germany and Europe most planned hydropower projects - we have already recognized that battery storage on such a large scale won’t work. That’s why our greens want hydropower to be the storage - are Meanwhile canceled. Simply because it only works with massive tax support and that not only to make it run but constantly. And that’s simply way too expensive..
Lots of new tech to improve solars are in development or about to hit markets and even without them they are already feasible in many places across the globe.
Lots of new tech to improve Nuclear power are in development or about to hit the markets. AND: if we had invested 10% of that money we’ve so far wasted on incentivizing renewables, then we would already have all that tech available for decades..
Where I live we produce one hell of a lot of Hydro Power. Interestingly our BC Hydro also gets really cheap power from renewable and nonreturnables on the open market because is easy to turn off and on, where these other markets cannot. I think grid level power storage is going to change this in a big way and remove this real cheap power that BC Hydro has been getting super cheap. BC Hydro has been promoting the use of roof top solar by buying power directly from uses, at retail prices.
@@Nelsongrantscams I said retail as the home producer gets the retail credit. They still use more power than they produce across the year. BC Hydro keeps giving me credit when they do a Peak Power Saver. I have people say "Why do you do that?" and I tell them that it is fun and I found out my basement dehumidifiers suck power. I am looking at putting in a level 2 power charger for my car so I can qualify for a lower rate on off hours and I just tie into my drier power line..
Viking you should do a vlog on the materials in PV ....it looks like 280 million ounces of silver will be consumed each year for the next 10 years.. thats nearly 20% of all global silver mining...
Yes, Sam. I would have put solar on my roof here in NZ but at my age not worth it. No subsidies or encouragement here although economics are sound for people with longer time horizons. As we are substituting Solar for fossils, world wide, we have another surge in demand from AI datacentres as announced at Trump's announcement of 500Bllion investment with Softbank, Oracle and chat GP.
I would say that total S-curve is probably too extreme, as they would be multiple stoppers in the way. Different markets, each one with each S-curve but that they could take time to start, so probably a little slower that than projection. BUT, that said, in the end, it will be similar. Lots, and lots of solar. I see a lot of potential in "agrivoltaics". Because land it will become one of the constraints, agrivoltaics allows a doble production, agriculture and solar energy, it will become a common occurrence in not so much time.
Do I agree? Of course! Disagreeing with Tony Seba at this point, seems like arguing over whether or not water is wet, or fire is hot. I just wish my local utility (BC Hydro) understood, since I heat my two suite house with electrical baseboard heaters, and there is a big tree that shades my house. I want the tree to stay even though it limits my solar generation potential. So even if I ever get around to installing heat-pumps (no contractor will do that for me, for fear of asbestos in my old walls), and repairing my garage trusses, so its roof can support solar-panels, I'll still be dependent on a utility that still thinks building dams is wise. (though maybe with better insulation, some new windows, a big enough battery, and a bigger backyard panel support structure, I'd be able in install enough solar panels, to disconnect from the grid, but all isn't cheap & the pay-back might be too long)
In the future most of the power will be created by solar panels, this power will be used to climitice deserts and provide water, still there is a windmill that is the best but man can't see it.
Reality is that we are at all time high at fossil fuel consumption! Can't use renewables as base load because of the fluctuation. It creates unpredictable energy prices. As much as I love renewables and I would be all in on them, economists' charts and research on this issue shows it clearly. Just look at Germany. Therefore I changed my mind and there is nothing else than nuclear as a clean, reliable energy source! This is the cold hard true. Switzerland already agreed on to build new nuclear reactors. They saw how Germany messed up it's energy infrastructure and now they run Germany on coal! CO2 emissions skyrocketed. Energy prices skyrocketed too. A regular household paying 4x the prices as other nations! Businesses going bust left and right!
As a German 🇩🇪 I have to fully agree with you. Unfortunately. We’ve waisted aprox. 1 trillion on the „Energiewende“ and all we’ve got is a broken country. 😢
Problem with solar is if everyone is using it in the day then not enough energy is available for charging the batteries for night time use. At night when, if we all have electric cars, we will be changing them. Then there is all the other use of electricity at night, industry, kettles, TVs etc.
If everyone had electric vehicles already, we would be charging them between 10am-4pm when there is excessive solar, and during other times when the grid has excess capacity e.g. windy hours or early a.m.
Modelling ,,,wind ,solar and batteries ...the cost to install enough to overcome the lack of generation at night and during periods of little wind , is enormous and is simply unaffordable. Then comes the environmental damage and land demand of vast areas of wind turbines and solar panels . Then comes the toxic waste disposal problem when they come to the end of their relatively short lifespan. Then comes the enormous cost of replacing them all to maintain power delivery. Claims that wind and solar will replace coal ,oil and gas are delusional. There is no transition to renewables , there is only an addition of renewables as the global demand for energy continues to increase significantly every year.
Solar and battery storage in every house exporting to the grid.... or disconnecting. Who pays for the grid? until now large corporations have charged you for energy and a connection fee, mostly by taking over infrastructure built by governments. There's a lot of big investors worried about their gravy train.
With rare exceptions, it is NOT economical for any household or business to be totally off-grid... possible perhaps, but very expensive assuredly. 90+ % will stay connected... and the connection fees pay for the grid... like they already do!
Pakistan suddenly had a energy crisis as there were too many solar panels coming online making the energy grid having a problem supplying power at a profit (because many power stations are running at lower output)
The quickest path to clean sustainable energy is to take advantage of every source of clean sustainable energy, not merely solar and wind. We must develop solar, wind, hydrologic, geologic, and modular nuclear reactors which recycle their spent fuel.
At least someone understands this, the sun doesn't always shine and the wind doesn't always blow. Nuclear fission produces loads more energy than either wind or solar and takes up far less square miles. Problem is all the green tards that spew crap from their mouths about nuclear without knowing any of the facts or reading the reports. I live in Connecticut and 35 percent of out electricity comes from one single nuclear power plant in Waterford Connecticut, no need to deforest thousands of acres to produce the same amount that three reactors can, no need to take up grazing lands that animals need for survival. Annual output of the millstone power plant is over 17,000 gwh, how much wind and solar would be needed to produce that.
@@williammeek-h2o Of course it comes down to cost. But looking at average cost is not the most efficient way to power the grid. In some regions and climatic conditions solar or wind won't be cheaper.
@ That is what national grids are for. Sure, the wind doesn't always blow and the sun doesn't always shine in a given spot. But on a continental scale, ya, it does.

The best solar company in Australia just installed my new solar system.
Check them out here:
www.resinc.com.au/electricviking
I´m all for it but why does everone always mix energy and electricity?
I've mentioned this a few times here, but I work for the world's largest solar panel manufacturer, we alone produce just over 100GW of solar modules/year, and are sold out completely for the next few years, and there are 4 other companies who are building about the same capacity as we are, with a dozen other companies equaling our combined build capacity. In short, the global annual build capacity of solar is 1TW, and growing, every year, which is equivalent to: ~2000 500MW gas power plants, which produce energy at about 1/3 the cost of gas. It's easy to see why there's virtually no new gas power plants being installed in the world, nor will there, and why hundreds are shutting down, every year. Coal is long dead and nuclear is DOA.
Why is China building new nukes. 21 more in the pipeline. You solar guys are a bit ignorant.
The state of f'ing Texas subsidize the building of gas plants...
Pretty much. I'm not in the industry and even I can see it.
If solar is 1/3 cost of gas then why do countries that use lots of solar have such high electricity prices? (Germany UK Australia for example)
@@DGlass-yg8xk I don't know about Germany, but in Australia (where I live) solar is bring the cost down. Our prices are high after years of no government policy and a lack of investment in infrastructure. Thanks to the cheap cost of solar, it's being deployed regardless of gov policy and prices are coming down.
The PV panels on my roof are 35 years old and still powering my off grid house.
yeah the pannels dad put up when i was a kid are still running although we got new ones also the capacity on those 90s pannels where never amazing to start with and they did reduce a bit over time but batterys we have had to replace a couple of times despite being carefull on the cycles
Awesome! 😎
Can you also tell us the difference in production new vs now i just want to see that they are still effective even after all this time
We had the power out for over 2 days after a storm funny how the nay sayers in my street asked to put there perishables in our garage fridge and charge laptops and other devices. From our Solar, battery and EV.

Glad you think so!
@@electricvikingi think so too
It makes a lot more sense for developing countries to go to solar rather than build coal plants or whatever, especially places poor enough that they don’t have an existing power grid. Microgrids can be made with very little money and no connections to a larger grid. There’s an assumption that places just electrifying now must go through the same centralized fossil fuel grid pattern as wealthier countries, but it doesn’t actually make sense cost-wise, not anymore.
The biggest advantage is that energy is not controlled by other countries
Leapfrog, just like adoption of mobile phones without first getting landlines
@ Exactly. I think of that example a lot when thinking of renewable energy adoption in poor places.
@ I’m convinced that this, at least as much as climate if not more so, is why China is pushing SO hard to move to renewable energy and EVs. They have very little petroleum of their own, which makes them dependent on middle eastern chaos. And since China doesn’t have the bad imperialist/colonialist habits of the US and Europe, they’d probably be happier with a bunch of independent countries they can trade with, not proxy wars, civil wars, and the occasional US “antiterrorist” action. And the US squanders blood and treasure in the middle east and Africa mostly for the sake of oil. China wants to wash their hands of it. They want their allies to wash their hands of it.
@@davestagnerif you think China does not flex imperialist power you're delusional. Doesn't mean US is better or morally superior, but China absolutely uses their power to get what they want. Belt and road.
I’m gearing up for solar. First I got to re-roof my house by myself. Then I’m going to buy and install my own solar. Right now stocking up on tools and roofing.
That's awesome 💪 we need more of that enthusiasm!
The way to go is solar and battery. I installed roof solar and looking for batteries by the end of the year - or smaller battery and a car to power the house at night and go off the grid.
That was silly
Quite possible in the future when V2H is mainstream. A house battery is still needed to keep things going in case you need to nip down too the local fast charger to cart some energy back to the house.
I agree with the sentiment of most of this. One caveat I'd add about the continued reduction of the cost of solar cells is that they already only represent a small percentage of the total cost of the installed solar system. Hypothetically if tomorrow the cost of solar cells fell to zero, the total cost of installing 10kW of rooftop solar would only fall by about 10%. Hopefully the next leap forward in solar advancement will come from more efficient solar (e.g. tandem cell perovskite) which can achieve the same capacity with fewer solar panels.
Ethiopia banned the import of non-electric vehicles on January 29, 2024.
This made Ethiopia the first country to completely prohibit internal combustion engine cars.
Nope - St. Helena has done so as well.
Norway has also already finished the transformation.
@@martinv.352, 88.9% of new passenger vehicles sold in Norway in 2024 were battery electric vehicles (BEVs), so Norway has not "already finished the transformation". Norway has a goal of 100% electric in 2025, but it will probably be around 95%, and it will probably take another 5 years to move the heavy vehicle market to 100% electric. Only 26% of Norway's auto fleet is electric, so it will take a while to replace the existing ICE cars.

Fusion is shining down on us from above. We have the tech to harvest this free fuel. Thanks Sam!
Fusion isn't 30 years away, it's 10 billion years old!
I've had solar cell panels on my boats since 1981 to charge the batteries. No problems at all. Even in cloudy weather it works fine. It helps a lot that in Norway the sun never sets properly in the summer months, just for a couple of hours and it doesn't get dark. The same goes for leasure houses and cottages. And the panels cost much less than a few years ago and last "forever".
Sam, the counter argument is that while renewables are cheap they are not as profitable as fossil fuel installations so companies will continue to invest in them and push governments to back them up. Can you make a video about that? Thanks! 😊
Yes, utility in my area, Ca Bay Area, charges customers for their grid “improvements”. So if a gas plant costs more they will damn well build a gas plant. So they can charge us more.
People will leave the grid . Batteries are cheap enough now for consumers to afford them
It’s a bit distressing to hear naysayers point out that the sun doesn’t shine at night and that it’s not always windy. Not because it’s true, but because can they really think that anybody has to be told that? The fact that so much work has gone into energy storage (and not just batteries, also hydroelectric, gravity batteries, heat storage etc) implies that, yes, we actually did know that, and no, we are not waiting for the sun to stop setting.
Actually, the sun ALWAYS shines on a goodly portion of Earth's surface. If HVDC lines could efficiently transport energy east and west around the globe, and south to north from tropical region to northern countries, then no storage at all would be needed!
It is technically feasible. OBVIOUSLY, going all the way in this direction would be financially excessive. But so is storage without such interconnections! So, the answer lies in a cost optimum between the two (plus a few other ways to address wind and solar intermittence).
Always funny when somebody comes along with "It was cloudy today, if I had solar it wouldn't have produced anything!", as if they're the first amazing genius to have figured this out. Also it's not even true, anyway. Some people on Will Prowse's forum are getting power from moonlight! (not a lot, mind you)
In Southern California, a rooftop solar system pays for itself in about five years. After that, the energy continues to flow. Of course it is economical to put in solar there. It costs less than one fifth the price of the energy from the utility.
You are a consumer. That's all upside for you.
Think what it looks like for an investor planning to invest a few billion in energy infrastructure. They have the prospect of investing in a project that is easy for competitors to compete with, where turnover is low and where margins are cut to the bone to sell the electricity.
Compare this with fossil fuel projects where the barriers to entry are high and the margins are consistently high.
This is why, without subsidies, the transition is just not happening as you would expect based on the comparative costs of solar vs fossil fuels.
Because investors don't go where costs are low. They go where profits are high.
@@michaelrch That all depends how things are structured. It costs money to build another 1 GW coal or gas plant, it requires fuel and maintenance. It may be cheaper to build a battery and store the excess solar from rooftop solar during the day which you didn't have to pay for and release it as needed.
@ fossil fuels have made the price of electricity so high, that even without subsides, payback time for home solar is just a few years.
Thanks Sam for your endurance in getting the facts into the public domain. Always inspirational j

The ULTIMATE in power generation is to have a distributed power grid - it's better for the land AND security. Can't target a power plant if the whole city is providing power. I also really like the idea of having excess electricity - there are plenty of uses for cheap excess only energy - eg run AI datacenters with older less efficient hardware. Have them pause the workload when solar isn't generating. Pump water up a hill to provide hydro power later, crypto mining whatever. Then at night have the systems pause, where you only run the latest most efficient workloads.
My panels are 20 yrs old , clunky and heavy but still working fine . My panels were $800 each. The equivalent now is $100 😊😊😊
They are less effective than new ones and degradation comes additionally..
Somebody up the road from me has what looks like a 100w panel (though it's really old, it has those circular blue cells, so it might be 50w) laying out on the street, propped up on their flowerpots, and presumably still producing.
10kW solar plus 13kwh battery and I’m effectively off-grid as well as outages are a thing of the past.
How much did those batteries cost? I have built two 8kwh packs that total $3k or so. I would need at least twice this for my meager 1100 sq ft townhouse. I live in a townhome that has limited roof space and in winter I get no sun on my roof. I love solar, but it is not economical for the majority of people. IF batteries were as cheap as solar panels
Then no problem. And they might be in a few decades, but right now: no.
how about the genset for winter, you haven't mentioned that, its impossible for you to be off grid and live anything close to a typical grid connected house. In winter you won't have enough solar to run your house never mind charge the batteries.

Let's acknowledge that Australia presents a best case scenario for solar: very low installation cost even for residential solar. Not easy or impossible to get there in most other regions of the world as the module cost is only part of the cost, the others are labor, permitting, shipping, racking, and fees.
And also historically high consumer energy prices.

How many solar panels are needed to refine a ton of steel?
Question 1: From ore or scrap steel? There is a huge difference
Question 2: in what length of time? 1s, 1m, 1hr, 1 day, 1 week, 1 month, or 1 year???
If I know the answers to Q1 and 2... especially Q2, then I can answer you.
@@st-ex8506 But you did not answer Q1 Q2 . Go with the Ore question.
What type of solar panel? What size? Where on earth is it located? What grade of iron ore are we talking about?
@@mikewallace8087 The original question is non-sensical without knowing in how long a time you want that ton of steel produced.... as well as other parameters
But let’s give it try:
It takes about 4 MWh of electricity to make one ton of steel, using green hydrogen for the reduction (instead of coal) and an electric-arc furnace.
A kW of solar panels produce on average about 1.3 MWh in a year… more in Arizona but less in Germany.
So, you need about 3 KWp worth of solar panels (i.e. 6-8 panels depending on the models) to produce 1 tonne/year of steel. To know the size of the solar park needed, just multiply by the yearly output you want your steel mill to have!
The steel industry is going to migrate from the places where there is (or was historically) iron ore and coal resources, to places where there is iron ore, and plenty of sunshine! That sounds quite a bit like Australia, China or Brazil, doesn't it?
Obviously, the production of steel from scrap metal is best done regionally!

Solar is the most important where you live but where I live there is no chance solar alone can get us through from late October - late March, we need wind or cheap long term storage...
Yes, indeed! So what? Wind and solar tends to compensate each other's intermittence! No long-term storage is needed... with some exceptions of the northernmost countries and regions.
for 80% of the world's population, solar alone is sufficient.
@ Your 80% share is somewhat exaggerated IMHO, but you are fundamentally correct. A very large part of the world's population would be fine with only solar + storage obviously.
The price of batteries is plummeting, and there's a ton of research being done on making them even better, cheaper and longer-lasting. Not all of that research will come to fruition, of course ("huge groundbreaking game changing batteries" get hyped up by certain youtubers every single week ;) ), but some of it will. Once upon a time they thought the best lightbulb filaments would be Chinese people's hair.
@@st-ex8506 The issue is that it is hard to overbuild for wind. With solar you can build it like 3 times more and it will ensure that even if there is less solar radiation on some days, it can still cover your needs. With wind the difference of when it blows and not can be massive. You can overbuild it 10 times but when there is no wind there is no wind, and when there will be wind unless you have huge next gen longer storage batteries, you will need to heavily curtail it. These challenges will be solved in future but at the moment unfortunately it is an issue in colder climate countries that winter season can be a struggle when using just renewables. Mainly because we do not have massive and cheap longer term storage for wind which is less predictable as solar. Not to mention that it is also hard to overbuild wind as it is now more expensive and a number of people are very much against "them windmills that cause cancer"...
Good that you mentioned the tough stuff that is getting fair participation of consumers. Regulations must transform to enable full consumer energy resource CER participation in the NEM.
Please keep in mind you live close to the equator.
About time too. My parents installed a solar water heater panel on the roof in 1983. It was a brand called Elesolar (I think it was Italian). I always wondered as a child, why nobody else had one?
Because financially it never pays off
In Germany we had that stuff as well because it was highly state-supported. Since that ran out nobody buys them anymore.
@volkerr."muh payoff". When you're the only house on the street with hot water in a wnter power cut. That's the payoff.
Solar must be matched with storage or all the advantages are lost
I agree, the more energy that is stored from renewable, all fossil fuel assets will be threatened as a stranded asset and public utility commissions will be forced to lower the price for consumers based off their required revenue formulas.
Great video Sam-telling it how it is and will be!!!
Always!
I work in the solar industry in the Global South and the switch to renewables is going much faster, because the advantages of not having to invest as much in centralized infrastructure is massive and the irradiance obviously is much higher. If it's possible to include storage at a lower price, they will surpass 'the West' in adoption as well as economic growth.
one of your best videos!!!
Thanks Mate!
Solar PV is so cheap these days. It’s a no-brainer if you’ve got the roof space.
Solar needs 0.1 gram of silver per watt that is 100,000 metric tons of silver per terrawatt. China want to make another 8 TWs of solar but there is not enough silver left in available supply
Which kind of solar?
Nice work this video, love your work, information and flexability of the mind is the new currency.
Much appreciated!
Right on. Solar has no moving parts, a huge advantage over wind in my opinion (practically zero maintenance cost!). Any other source, old or new, does not come close in initial build cost and maintenance cost.
People tend to think they're complementary because wind power is also on a decreasing cost curve (and wind blows at night).
But yeah, I think solar will be the bigger part globally, because it's hard to beat no moving parts. Unless you're in Ireland, where it's always very windy and very overcast.
its not just renewable energy that is wasted so is 1/2 the fossil fuel power. battery's can not only be used to improve that efficiency they can be used like we use water revivors in plumbing to keep the pressure up on lines allowing more more efficient distribution of power along existing network, if we place them strategically like water revivors (for eg in the residential clusters the power needs to be sent to)
Great video, right on, as batteries become safe and solar comes down solar makes sense, everywhere.
Not a fan of roof top solar, I have a wood roof. For my current solar I used a ductile iron pipe with up to six panels mounted and a stone dead man foundation to take wind loads. As I have black locust on the property (northeastern US), I am considering the replacement of ductile Iron with Black Locust and a black cherry frame. I think it should probally last the lifetime of panels. I've started growing white cedar and incense cedar (plan on planting red cedar) for future structures.
Thats for the expansion of system to charge a vehicle.

Prices for electricity in Germany are sky rocketing. We pay on average aprox. 35 Cent/KWh. There’s so many additional costs and taxes included - mostly needed to finance the renewables and the highly over dimensioned grid.

Having a battery for your house almost never pays off. The money you save vs what a solar roof installation and the cost for the storage battery is, it takes aprox. 20 years to pay off. And that only if you stay at home 365 days a year. I live in southern Germany and we are every year in August one month away. if you take that into account, it never pays off.. you need to replace the battery after 20 years the latest..
We just bought an EV with a bidirectional battery in it (2025 Chevy Equinox). Am in discussions with a local electrical company (which specializes in renewables work) to get the charging system installed so that the EV will act as battery storage for the house in event of power outages. Our solar arrays presently provide about 62% of the electric needed to run the (all electric) house. I've been considering adding another array--that'll be a trickier install (hence more costly but hey, it's only money) and that'd get us up close to 100%.
primary energy production in Germany is still ca. 80% from non renewable energy. Only electricity production ist aprox 50% by renewables. Including imported electricity mainly produced by coal and nuclear power.
I agree!
I have a 100 KWp Photovoltaik. In Summer there‘s a lot of electricity production, at least during the day. During the night there’s no production 😅 and in winter there’s as well almost no electricity production. So we need 100% backup for PV
100Kw? Do you realise how big that is, or are just lying in some lame attempt to discredit solar?
My old job had 13Kw and the panels were bigger than the floor area of my flat. Where are you putting this 100Kw? Do you own a whole field? What are you doing with the rest, because at peak production that's far more than enough to run every appliance in a house non-stop.
"😅" indeed.
@ ?!? It’s not on the roof of my house. although it’s on the roofs of several farming buildings in eastern Germany. The usual size of such power plants is up to 750 KWp. Because that’s the maximum size for a better tax incentive. 😜😁
I only own a part of it with two inverters. Which is in my case a bit below 100 KWp.
It’s 100% going into the grid.
Just two technologies are capable of solving the energy over the next 20 years…. Solar panels, both commercial and domestic, and V2G. Once the EV revolution is “complete” (once ICE vehicles are reduced to enthusiasts only) the spare battery capacity of collective EVs plugged into the grid at any given time, will be massive.
You need oil to mine the materials for the solar. You need oil to transport and install solar. Solar is the way, but we have need for decades of oil production to build solar out globally. Not all geographies are as suitable to solar as Australia is. In Australia, no doubt solar can do it all. Elsewhere not quite yet.
Not sure how many other people have experienced this in Australia. Had a friend who told us yesterday that the solar company they contacted, told them it is not worthwhile installing solar panels after seeing their power bills of the last 12 months ($170/month). Not sure if the solar company got it. Our friend does actually want home battery as part of the system as well. I cant see any reason why the solar company has said what they have said. Their roof gets enough sun exposure. Anyways, i have passed on your installer Resinc’s details to our friend in Melbourne
The government should finance batteries for every suburb, or for every home (whichever is cheaper). And every house that is newly built must have enough quality solar panels to power it. That is the cheapest way to rapidly transform the grid to solar energy.
@@elephantintheroom5678 over 60% of electricity is used by non residential consumption (industrial, commercial).
Nuclear electricity economics in the UK : Hinckley C has a strike price of GBP190 per MWh. Eg 19p per KWh. British consumers charge their EVs at night paying 7.5p per KWh night rate. So the first question for nuclear fans is : who pays the 12p subsidy per KWh to fund their expensive nuclear reactor ?
1. question: why is it nowadays so expensive to build new NPPs? Might it be due to way to
Much and too high regulations? That constant chance during construction period..? 🤔
2. question/ if you add costs for back-ups and/or storage capacities for renewables (and they are as well highly incentivized by tax payers too), is it still cheaper then..?
And how long will a NPP run and how long does your PV? How long will battery storage work until it has to be replaced? Probably on double costs then due to inflation etc…?
@volkerr. The nuclear power industry promised "NP will be too cheap to meter" and "meltdown is impossible". They are liars. My solar is not subsidized in NZ. Build your NPP with proper insurance and no public guarantee or subsidy and if you cannot then admit that nuclear power is too expensive to sell in a free market. As for whining about bureaucracy, in the 1970s the coal industry whined that sulphur filters were too expensive but the EPA regulated regardless. We quickly found out that the sulphur filters were much cheaper than the coal power plant whiners had claimed. Safety is important, and if NPP cannot afford safety then we shouldn't build them.
In Germany our installed PV capacity is able to produce more than 100% of electricity needed. When the sun is shining. And only on certain days in high season summer. 😜
By 2035 it is expected that solar panels will have lifespans in excess of 30 years and produce 50% more electricity than the current panels! Solar panels, wind turbines and hydropower supported by Grid storage batteries are certainly the future of electricity generation in Australia and many countries worldwide!
Awesome news!
Thank's
My relatives in the Netherlands, which isn't ideal for solar power, and those living in Pakistan are using solar panel for the same reason: the cost of electricity is very expensive.
In Germany and Europe most planned hydropower projects - we have already recognized that battery storage on such a large scale won’t work. That’s why our greens want hydropower to be the storage - are
Meanwhile canceled. Simply because it only works with massive tax support and that not only to make it run but constantly. And that’s simply way too expensive..
What's the difference between bribery and extortion?
Lots of new tech to improve solars are in development or about to hit markets and even without them they are already feasible in many places across the globe.
Lots of new tech to improve Nuclear power are in development or about to hit the markets. AND: if we had invested 10% of that money we’ve so far wasted on incentivizing renewables, then we would already have all that tech available for decades..
Where I live we produce one hell of a lot of Hydro Power. Interestingly our BC Hydro also gets really cheap power from renewable and nonreturnables on the open market because is easy to turn off and on, where these other markets cannot. I think grid level power storage is going to change this in a big way and remove this real cheap power that BC Hydro has been getting super cheap. BC Hydro has been promoting the use of roof top solar by buying power directly from uses, at retail prices.
BC Hydro only pays wholesale if anyone has excess power, they once did pay retail but realized this was a fools game
@@Nelsongrantscams I said retail as the home producer gets the retail credit. They still use more power than they produce across the year. BC Hydro keeps giving me credit when they do a Peak Power Saver. I have people say "Why do you do that?" and I tell them that it is fun and I found out my basement dehumidifiers suck power. I am looking at putting in a level 2 power charger for my car so I can qualify for a lower rate on off hours and I just tie into my drier power line..
Viking you should do a vlog on the materials in PV ....it looks like 280 million ounces of silver will be consumed each year for the next 10 years.. thats nearly 20% of all global silver mining...
im currentl;y sitting here waiting for CEC to approve the sigenergy 10kw hybrid inverter to get 24kw batteries and panels installed
Yes, Sam. I would have put solar on my roof here in NZ but at my age not worth it. No subsidies or encouragement here although economics are sound for people with longer time horizons.
As we are substituting Solar for fossils, world wide, we have another surge in demand from AI datacentres as announced at Trump's announcement of 500Bllion investment with Softbank, Oracle and chat GP.
love from Pakistan
High Sam I live in the UK enough said
They should be able to use the aluminum frames on solar panel over and over for 100s of years, maybe longer 👍
I would say that total S-curve is probably too extreme, as they would be multiple stoppers in the way. Different markets, each one with each S-curve but that they could take time to start, so probably a little slower that than projection.
BUT, that said, in the end, it will be similar. Lots, and lots of solar. I see a lot of potential in "agrivoltaics". Because land it will become one of the constraints, agrivoltaics allows a doble production, agriculture and solar energy, it will become a common occurrence in not so much time.
Do I agree? Of course! Disagreeing with Tony Seba at this point, seems like arguing over whether or not water is wet, or fire is hot.
I just wish my local utility (BC Hydro) understood, since I heat my two suite house with electrical baseboard heaters, and there is a big tree that shades my house. I want the tree to stay even though it limits my solar generation potential. So even if I ever get around to installing heat-pumps (no contractor will do that for me, for fear of asbestos in my old walls), and repairing my garage trusses, so its roof can support solar-panels, I'll still be dependent on a utility that still thinks building dams is wise. (though maybe with better insulation, some new windows, a big enough battery, and a bigger backyard panel support structure, I'd be able in install enough solar panels, to disconnect from the grid, but all isn't cheap & the pay-back might be too long)
In the future most of the power will be created by solar panels, this power will be used to climitice deserts and provide water, still there is a windmill that is the best but man can't see it.
excellent
Thanks!
Ya ok 👌🏼,, that sounds accurate…..
NOT .. I highly doubt this by 2035 .
I am a climate denier but I belive in electricity.
Emirates has day and night functioning with solar and batteries alone
Dogs and cats LIVING TOGETHER, mass hysteria!
Half. No. Way. Batteries are not where they need to be for this. When battery tech improves I'll agree.
I have solar. I've built several battery packs at approx 4kwh each from prismatic LiFePO4 chemistry. It would take me decades to break even.
Right now, you can get DYI battery kits 15 kWh for $2k. and prices are still falling
Reality is that we are at all time high at fossil fuel consumption!
Can't use renewables as base load because of the fluctuation. It creates unpredictable energy prices.
As much as I love renewables and I would be all in on them, economists' charts and research on this issue shows it clearly. Just look at Germany.
Therefore I changed my mind and there is nothing else than nuclear as a clean, reliable energy source!
This is the cold hard true. Switzerland already agreed on to build new nuclear reactors. They saw how Germany messed up it's energy infrastructure and now they run Germany on coal! CO2 emissions skyrocketed. Energy prices skyrocketed too. A regular household paying 4x the prices as other nations! Businesses going bust left and right!
As a German 🇩🇪 I have to fully agree with you. Unfortunately. We’ve waisted aprox. 1 trillion on the „Energiewende“ and all we’ve got is a broken country. 😢
Thats fine. the rest of the world will just go off-grid solar and save money.
Have solar, battery and a EV have not paid for power since July 2023 in credit expecting no power bills of this year.
where do you live and tell me about your solar and home consumption,
@@Nelsongrantscams 13.2 kW Solar, 13.5 Battery I am on Virtual Power Plant, in Western Sydney NSW.
Investing in fossil fuel companies and ICE manufacturers is as sensible as buying property in South Florida.
Why would anyone do it?
No batteries, no distribution, no solar.
Problem with solar is if everyone is using it in the day then not enough energy is available for charging the batteries for night time use. At night when, if we all have electric cars, we will be changing them. Then there is all the other use of electricity at night, industry, kettles, TVs etc.
LOL
The plan is to massively overbuild so there’s loads of spare solar to cover poor weather.
Flawed logic. When ev’s are parked which is where they spend the majority of their life they can be plugged into the grid or be supplying it.
If everyone had electric vehicles already, we would be charging them between 10am-4pm when there is excessive solar, and during other times when the grid has excess capacity e.g. windy hours or early a.m.
@@gerryburde5663but most people will be at work between 10am - 4pm and won’t be able to charge 🤔
Modelling ,,,wind ,solar and batteries ...the cost to install enough to overcome the lack of generation at night and during periods of little wind , is enormous and is simply unaffordable.
Then comes the environmental damage and land demand of vast areas of wind turbines and solar panels .
Then comes the toxic waste disposal problem when they come to the end of their relatively short lifespan.
Then comes the enormous cost of replacing them all to maintain power delivery.
Claims that wind and solar will replace coal ,oil and gas are delusional.
There is no transition to renewables , there is only an addition of renewables as the global demand for energy continues to increase significantly every year.
Solar and battery storage in every house exporting to the grid.... or disconnecting. Who pays for the grid? until now large corporations have charged you for energy and a connection fee, mostly by taking over infrastructure built by governments. There's a lot of big investors worried about their gravy train.
With rare exceptions, it is NOT economical for any household or business to be totally off-grid... possible perhaps, but very expensive assuredly. 90+ % will stay connected... and the connection fees pay for the grid... like they already do!
Pakistan suddenly had a energy crisis as there were too many solar panels coming online making the energy grid having a problem supplying power at a profit (because many power stations are running at lower output)
The quickest path to clean sustainable energy is to take advantage of every source of clean sustainable energy, not merely solar and wind. We must develop solar, wind, hydrologic, geologic, and modular nuclear reactors which recycle their spent fuel.
At least someone understands this, the sun doesn't always shine and the wind doesn't always blow. Nuclear fission produces loads more energy than either wind or solar and takes up far less square miles. Problem is all the green tards that spew crap from their mouths about nuclear without knowing any of the facts or reading the reports. I live in Connecticut and 35 percent of out electricity comes from one single nuclear power plant in Waterford Connecticut, no need to deforest thousands of acres to produce the same amount that three reactors can, no need to take up grazing lands that animals need for survival. Annual output of the millstone power plant is over 17,000 gwh, how much wind and solar would be needed to produce that.
it comes down to cost. Wind and solar are the cheapest by far.
@@williammeek-h2o Of course it comes down to cost. But looking at average cost is not the most efficient way to power the grid. In some regions and climatic conditions solar or wind won't be cheaper.
wasting money nuclear slows renewable down
@ That is what national grids are for. Sure, the wind doesn't always blow and the sun doesn't always shine in a given spot.
But on a continental scale, ya, it does.
