The future of energy?

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.

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 :)

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?

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

What about stopping to erode or even repopulating the rain forrest?

[wichoswissvideo]

Excellent way to give a perspective of future of energy and actions that could be taken.

[solaimanabdullahelkhereiji]

Solaiman Elkhereiji, It is important that we start saving energy as individuals and societies and make this as part of our education and culture

[rkreike]

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?

[rubikfan]

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

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.

[jakeshaffer]

They fail to mention that the behavior change on the demand side also requires more time and is generally an inconvenience.

[samann]

what about nuclear technology? if we learn to use it very responsibly, it can solve most of our energy problems.

[physicsimpossible]

What we need is an arc reactor or a Tesseract :D

[rkreike]

If growing overpopulation is an important cause for climatechange,
then why is there so little talk about family planning during summits?

[panadudeTV]

GREAT PRESENTATION! Can't wait to go to Cambridge university!!

[SuperKorn]

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) .

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!

[Rizrizk]

Just watching the way how we generate our energy just makes me realize how outdated this modern world is.
