Every year, the world uses 35 billion barrels of oil. This massive scale of fossil fuel dependence pollutes the earth, and it won’t last forever. On the other hand, we have abundant sun, water and wind, which are all renewable energy sources. So why don’t we exchange our fossil fuel dependence for an existence based only on renewables? Federico Rosei and Renzo Rosei describe the challenges.

Did you Just forgot to mention Windenergy?! Good Video but some of your asumtions are Just wrong.
It may be more eficent to have decentralised Power Produktion via Solar than to produce in a Dessert that is far away olny exeption might be for example abudabi.
This Video is outdated and Not repräsentative of the current state of development in the renewable Technologie

Not to mention lithium ion batteries all the stuff mined needed to make those batteries create more co2 than the current system.

We should have listened to Tesla....

Nice video. Can you do a video on lithium ion battery?

It's a good awareness initiative. But TED-Ed is a famous platform and we people expect more from it. If oil and gas runs out in 50 years or some renewal energy will be there but what about all those 5000+ petroleum products we get from nail polish to aviation fuels. Not only renewal but oil and gas industries are also evolving. We are searching for more crude day by day and recent advancements in shale and gas hydrate will be a key source.

Easy solution: Nuclear Energy.

Looking at the comments, I'm a little shocked at how misinformed the general public is concerning energy.

Yay fossil fuels are gonna run out cause if it did fossil fuel plants will be useless cause Earth is dying

"[to develop clean energy alternatives] we need powerful incentives."
You mean, more powerful than the continued survival of modern civilization?

boring!!!!!!!!!!!!

Well stated and realistic. In some cases renewables can currently be cost effective, such as solar powered emergency telephones along remote highways where power is otherwise unavailable. But there are the considerations mentioned here that are currently real "show-stoppers" for commercial and most (definitely not all) residential applications. Here are a couple more pragmatic considerations: https://ufl.ae/videow/ErltIcFrtBw

I liked the video, but it ignores the impact that renewable energies have on the ecosystems.

All you have to do is raise taxes to pay for it! THAT HAS BEEN THE WHOLE PROBLEM ALL ALONG! DUH!
Alex McCree
Renewable energies are certainly an upgrade over fossil fuels, but it’s not the best option we have. Nuclear fission is our most powerful, efficient, consistent, and cleanest source of energy. We’d be fools to not pursue it. Choosing renewables over nuclear fission is like choosing leather armor over steel armor when you want maximum physical protection. It’s just not something you’d logically do.

Batteries are a triumph of science—they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.
