태양 에너지의 밝은 미래: 마틴 그린 교수와의 인터뷰 3부 중 3부

What is the future of global sustainable power? Professor Martin Green believes the prospects look very bright indeed! So, yeah, it’s an interesting future. You know, even things like producing iron, you can do it using electricity as a source, but it’s been more expensive than traditional blast furnaces and so no. But if electricity’s free, it changes the whole equation. So, a very exciting year that we are entering into, as the world switches from its dependence upon fossil fuels to something more sustainable, namely wind and solar.
