- Today, we consume a truly vast amount of energy - with demand continuing to skyrocket at an alarming rate. We know that producing this energy has significant environmental impacts and emitting so much carbon dioxide into the atmosphere could cause catastrophic climate change. In this film, three academics look at wind power, carbon capture and storage (CCS) and material efficiency as examples of how we can cut our C02 emissions. They suggest that we must act now in order to avoid the serious risks of man-made global warming, one of our greatest challenges in the 21st century.

The best thing about videos like this one is that it get's people talking, out of talk comes innovation and invention, and that is something more valuable than the oil, and other finite resources we must learn to live without.
Isn't it refreshing to know that so much mental and physical effort is being put into protecting the environment, and minimising humanity's demand for resources?
Upon watching until 4:18 when the speaker was saying "We must think about how our other energy usage could be transferred into electric supply then we could've caused so much generated electricity cleanly." I SUDDENLY HAD AN IDEA!
--because there was a clip of a bunch of vehicles on the road during that statement, I thought: why not generate electricity from the vibrations or whatever forces vehicles generate on the concrete pavements? (I'm no engineer though)
People usually complain about the roads being the cause of heat island effect, now with that idea, at least it would provide more use right? Especially in megacities where there are always vehicles and the traffic is terrible.
Also! (Idea #2) Since concrete roads are huge heat absorbers, why not generate electricity from that? An innovator should design some LITTLE contraption-whatsoever for that :)
The key is mixing Wind, Tidal, Solar & Energy storage. Energy storage doesn't need to come from battery's we can use underground balloons, pumped storage, heated salt storage the possibility's are endless. We just need the government to act & invest diversely without selling it off to foreign owners that can put pressure on us down the line or raise prices.
Thanks for your question. The city at 1:22 is San Francisco.
God bless everyone still waking up everyday chasing their dreams salute
They fail to mention that the behavior change on the demand side also requires more time and is generally an inconvenience.
part 1 - Demand is not the cause, it is a multiplier, which is still important. If we had 100 billion people on the planet but we had sustainable energy and resources then it wouldn't be a problem. Also they said in the beginning that demand for energy grows by 2% each year, which is caused both by increased demand by individuals, and an increased number of individuals.
What about stopping to erode or even repopulating the rain forrest?
+till kue Good point!
+till kue The rain forest actually grows extremely fast on its own.
However it is interesting you brought this up, as 30 years ago this was considered a major topic, now ? nobody seems to think about the simple solution trees provide.
Because of erosion replanting is often is not possible.
Shouldn't there be a lot more energy from waterpower?
Falling water, waterbassins, wave- and tidal energy ...
And there should be more and better artificial waterways ...
Or not?
what about nuclear technology? if we learn to use it very responsibly, it can solve most of our energy problems.
Excellent way to give a perspective of future of energy and actions that could be taken.
What we need is an arc reactor or a Tesseract :D
I'm no expert or anything on this but, if a car is moving at 60mph, then there must be air going at 60mph against the surface of the car (right?) So, I was thinking if cars could have wind turbines inside the grille, and several of them, it would generate a lot of electricity that powers the car,it would be able to run purely on wind power, so that means we'll be using 50% less oil (transport) .
Solaiman Elkhereiji,It is important that we start saving energy as individuals and societies and make this as part of our education and culture
4:25 looked AWESOME it is very fascinating.
Just watching the way how we generate our energy just makes me realize how outdated this modern world is.
Thank you for this wonderful video, and I do like putting the references at the end. It's appreciated
GREAT PRESENTATION! Can't wait to go to Cambridge university!!
Great video! I think this is one of the most important topics to consider in physics and other related subjects, as it is so current, and essential for the environment. I think that although finding a way to more efficiently produce energy is very important, the amount of energy that we consumers use is the cause of most of the problems. (If we can find away to live a good lifestyle without as much need for fuel/energy, then less fossil fuels would be required by power plants, which would obviously lead to a decrease in CO2 production.) One way in which I think we could make a big difference in reducing fossil fuel consumption, is to design and manufacture vehicle engines that can efficiently turn a totally renewable substance, such as solar power or water, into enough energy to match the energy released from combusting fuels.
Thorium reactors are the answer. 150 mile electric car battery. Turn gas stations into a quick change battery station. Don't own the battery change them out with varying degrees of mile capacities. 50, 100, 150, 200 mile batteries.
The problem with on land wind generators apart from the esthetics is that the land which supports the towers can never be used for agricultural land again. which is presently 10's of thousands of acres across Europe.
Just a suggestion to the intellectuals at Cambridge, lower the volume of music when someone is talking, especially in a low pitch voice. We are here to see the impacts and alternatives in energy, if we wanted music, we'd be listening to that only. Just a suggestion!
HI. I wanted to know if you can tell me the name of the music that is used in the background at the first part of the video. Tanks
I think what will help the drop of energy use is the development of more efficient products a good example is LEDs.
Would be great if there was something to replace the electric element that heats up water. Which is used in electric kettles; washing machines emersion tanks, hair driers, electric fan heaters.
Any ideas?
If growing overpopulation is an important cause for climatechange,
then why is there so little talk about family planning during summits?
I would love to see more shows like this one.
I am going to take a 3 year course in Energy Systems Engineering Technologies.
Good for you. I do hope your studies are fruitful.
i watched this in class and this is very good!!!
Where is the wind farm pictured at 4:21 located?
I like your video very much. It's really great. I'll keep an eye on your channel. I am your fan and I will support you.
what name's soundtrack?
They make a great case for an RBE.
Nuclear + R&D = Future energy
1:20 better focus on cleaner energy.
because every year the energy consumption we use more and more. we might use it more efficiently but nontheles we use more. and there is no sign of stopping that.
so cleaner energy is the future.
the best thing whould be making fusion
Ewokah Dong goverments could start with placing power chargers and hydrogen fuel station at every pump/gas station. and maby force privit as well.
this whould stimulate sales.
rubikfan1 More simple would be, and read closely because this will work, mandate that all houses are to have evacuated tube hot water = 20A offpeak load that is currently used to heat the countries domestic water can then be used to charge domestic vehicles instead because the hot water will be heated by the sun (is mandated in Israel already, they dont fuck about because they cant afford too) = no or little rise in electric bill and drastic drop in oil/petrol usage. With no upgrade to infrastructure.. Do you follow and if so would it work and not be the most simple way to make dramatic change for little $$?
Brushless DC motors(generators) have existed for a while tho?
I think Hydro Dams are the most efficient and most useful method to solving this issue!
wind power will never meet the power demands not possible
Very well done video that looks at so many aspects of the issues. I had done a presentation that is on my website, Innovations in Transportation that explores ideas for more efficient transportation. Bill Kuhl
you should submit this to the new urbanism film festival.
Thanks for posting.
The best energy source is also binary cycle power generation plant.
In my area, the temperature of summer season is 30c° to 48c°.
Binary cycle power generation plants can b run with working fluid that have low boiling point.
Such as R245fa.
are there any activities set on this video?
What do you think is the best way to reduce the weight of automobiles: carbon fibres or aluminium?
Amazing!
Interesting video!
Why would we want to re-sequester the carbon from fossil fuel? The carbon is already trapped as a solid or liquid. We don't need to re-trap the CO2 if we don't burn the fossil fuel. Switch to nuclear and leave the fossil fuel deposits where they are. The ultimate in carbon sequestration is not to have released it in the first place.
I think this is a risky try 'cause with the co2 storage sistems we can loose the posibiliy to use the oxigen that is in the co2 for our breathing or for the animals... Does anyone see this issue???
i am working on future energy resources. and i think that our future of energy would be hydrogen. but the problem is that we dont know how to produce H2 in a more efficient way. but my aproaching more in technical field we may easily harness hydrogen from water. and since it is a renewable resource ,it is the best energy source.
Yes this is future of energy that we use in future thank you so much for all the scientist that they discover this free gift of nature to us
We need to redesign our cities and infrastructure to implement the use of the new energy innovation and be flexible enough to adapt and integrate in the future. The prime example is implementation of the mass transit systems that use the non conventional energy sources and reduce the use of cars.
🔥🔥🔥!
I am from NUST
And I think that one another major source of energy is water waves at sea
wind and solar on every home, commercial building around the word and with solar tied into things like cars,truck,18 wheeler ,golf cart , fences , trump wall etc that's how we go green with nuclear to help right now
Managed to mention nuclear power twice I think. Proper investment into nuclear breeder reactors and their use in conjunction with conventional thermal reactors has the potential to meet pretty much all of our energy needs for the next 100-1000 years. Obviously, the video is based around the research taking place in Cambridge, but whilst I agree with everything in this video, I think nuclear power will play one of the biggest roles in the future of energy
whats this is music?
The future of energy will arrive by the end of next decade in southern France, it is called Tokamake. The first comercially viable Fusion Energy Power Plant. It's prototype is already being assembled by ITERN.
@11:00 But hyper efficiency assumes economies of scale, which assumes massive production, which assumes huge wastage.
There is nothing efficient about hyper efficiency. Declining demand (people using things more responsibly) will wreck those companies who're not prepared to downsize their operations on a flip of a switch.
I'm certain if you hunt around you could find something, especially if its pertaining to Bio-fuels or maybe Hydro-electrical.
part 2 - The carbon sink of living organisms pales in comparison to the vast oceans of carbon sink in our fossil fuel gluts. And the difference between carbon in organisms and the carbon in fossil fuels is that carbon in organisms is IN NATURAL CIRCULATION. All of the carbon that a tree takes out of the atmosphere is in the tree itself, problem is when that tree dies it is almost never turned into coal and all that carbon goes BACK into the atmosphere.
I think wind turbine farms are kind of beautiful.
No radiation.no waste.clean energy.
understood
What's cheaper, building over capacity AND storage for wind and solar or building molten salt (nuclear) reactors. Even RE systems create chemical wastes which must be dealt with, either neutralized or isolated forever. Thus, the little bit of radioactive molten salt reactor wastes can be stored too. The only difference is that 80% of radioactive fission products decay into harmless elements in just 10 years, (the other 20%, just 300 years). The super long lived wastes (actinides) can be reused in the molten salt fuel, if closed cycle.
Why would ANYONE want to put CO2 into the ground without first chemically fixing it!
The way to deal with that is to put it naturally into the ground - as soils. This requires mega nuclear powered desalination plants for the water needed to literally green a desert. The nuclear power option could be sidestepped (to some degree) if water was instead barged from the mouths of the plentiful rivers worldwide. The byproducts: a very minute volume of nuclear wastes (comparatively) and LOTS of produce/vegetation.
If greening an entire desert is not enough to store the approx 2.2 TRILLION tons of excess CO2, then, we'll have to use diesel powered heavy equipment to MINE OLIVINE rock, crush, pulverize and distribute. It's like a fertilizer which sequesters CO2 into limestone when rained on. Eventually, it goes into the ocean and also counteracts ocean acidity caused from - excess CO2. This is also natures way of geologically storing CO2 on the order of millions of years.
Therefore, the discussion of liquid CO2 sequestration is merely directing people on the WRONG path (towards developing REAL solutions to safe excess CO2 storage).
Renewables should, however, be strongly developed AFTER machine automation can make them and their storage cheaper than coal!
Let's make this World a little Beautiful.
Let's reduce energy consumption, be more efficient
Let's produce more renewable energy
Don't worry people Carnegie wave energy from Australia will solve energy and water needs commercially in 2018
Thorium is a good source of energy
What about fusion energy?
Magnetic fuel cell powered by Continental crust movement
Our planet's crust is always in a constant move
Use the power of a earthquake to fuel a magnetic fuel cell to which then Is distributed to communities
Ok, when you figure out how to do that, please give me a million dollars because you'll be a billionaire :D
statikreg Deal!
what about non-renewable and renew
is there anyone who is working on the Wave Energy project?
The future of energy is just this, energy is a constant in the Universe this should be called the Future of Electricity or Power via environmentally sustainable technologies.
If only profiting from energy is stopped we'll see idea's pouring in, most definitely there's a better way on how we can generate our energy without further damaging the planet.
Part of the problem is that people feel the need to profit from their ideas. Because they are afraid people will steal them, they keep them to themselves. Millions of people have brilliant ideas, but often lack the knowledge or the money to implement them. If we were to let go of the need for profit, we could make great leaps forward.
Brother John Totally agree with you man. honestly, this is the reason I don't actually put something online, I don't know any other way for it cause it will most probably get into wrong hands. I feel bad but then I think just wait until I gather some momentum.
CCS will be like the clean diesel and clean coal sort of thing, we should be investing in clean generation, not investing in fossil fuels which will run out in a few decades regardless.
Cool
If the demands for materal and energy declines, would that means potential econonic crisis?
What about energy that takes CO2 out of the atmosphere.
wind power is great but how to store the electricity.
1:12 I think it is a very good idea to do this solar panels with some kind of artificial light that provides energy, so the sun is nopt the only energy provider in solar panels.
Put the CO2 into a dome with plants the plants will turn it into oxygen
not plants, algies. there are very well working projects testing that.
algies have a multiple times higher consumption of co2 per used m² (or m³)
How about we make a big sphere, covering the entire planet, and fill it with plants!
thats carbon dioxide. were dealing with carbon. it would just kill off the plants. :(
We are thinking about this completely backwards. Fossil fuels = lucky phenomenon a few generations were able to enjoy. We've got to get out of fossil fuel based logistics. Bring the farms to the cities.
Ocean water pressure can be used to spin a generator. Imagine that, endless out of sight out of mind clean energy that will never run out.
the problem with that is, it would hurt he pockets of the masters
Water or air, in air there's water, in water there hydrogen
Use roman concrete super durable
I think that we must turn to old technologies in the era of industrial revolution, i refere to steam generated not by carbon but by the power of the sun
Make fuels out of atmospheric CO2 via CCS, making transportation circular. Trees are still one of the most economic viable solutions.
CambridgeUniversity - why don't you mention the worlds rapidly rising population in this video regarding increasing consumption of energy?
unfurtunately fusion is always 30 years away , in the 90 it was 30 years away and still is today in 10 years it may be be 30 years away as well, there are a lot of technologies in energy generation but they depend on the price mechanism of this economic system, again energy is generated by very big private companies and state copanies so basicly the market is closed for the little investors, that;s why we may never know about some technologies that are not aproved by the big companies.
what about solar energy?
How much percent we are using energy from sunlight, wind, waves to transfers into renewable energy sources, for alternative energy today?
This can help our World reduction environmental pollution, threatening the living life of Human. (Do the climate change-global warming-caused hurricanes, drought and the variety of all the human species.)
Today world in the developed countries, are using large amounts of oil gas, coals and nuclear power plants, hydro-power dams for expansion economic.
This problem will cots, occur for the power source of the world's reserves shortfall, exhausted in the future.
I think sooner or later, this issue must proceed. Because according to the needs of economic development worldwide (EDW), also because the oil and gas energy, will be established in the future.
Think about how much percent of energy came from sunlight, wind and ocean waves on our earth everyday?
Shale gas is only temporary we need to look at look term solutions as shale gas will run out eventually
❤
Reduce the expensive investment in these new alternative sources and spend it on what we know works - nuclear power
Space Solar is the future!
Why?...
I don't know, just sounds damn cool!
in future, all cars will be driveress, driverless directly leads to light vehicles, this favours electric cars, as batteries for light cars are cheap (non-linear relationship). The cost of electricity is much less tto gas.
I like how at the beginning the show STEAM pouring out of these power plants . That should discredit the entire video because of the dishonesty.
Solar energy is the future.
That's right bcuz the sun is a star itself but also that would be hard
Very informative video!
I`ve figured out the storage problem which I will be putting to a government grant agency on Monday 14 November. I don`t think they really want to do it right or the same old faces will lose out financially. We do not need Hinkley Point or that deal, but it`s a political move, therein lies the problem.
Top 50 carbon emission locations listings accurate to street number is non-existence. Why? Is it because of corporate politics or economic politics?
