Hear what Bill Gates has to say about Innovating to Zero

In this intriguing TED presentation, Bill Gates talks about the challenges of making power sustainable.

TED, which stands for technology, entertainment and design, is focused on promoting "ideas worth spreading", and hosts talks by big thinkers in a range of spheres.

In this talk, technology guru Gates explains the challenges humanity faces in achieving carbon neutrality in the area of power generation. He discusses what he believes are five key approaches to large-scale power-related emissions reduction, then goes into a little detail on terrapower, a revision to nuclear power that, he says, is one of "hundreds of ideas" that we need to focus funding, research and investigation on if we are to reduce global carbon emissions by 80% by 2050.
