91热爆

We examine the technology solutions to achieving a clean and universal power supply, with a report from Silicon Valley on new Cleantech initiatives. Is there still a financial appetite to solve problems, from long-term power storage, to an affordable solar supply for poor Africans, in America's technology capital?

We also hear from the head of the World Coal Association, on why he feels there's still a place long-term for the world's most polluting fuel in global power generation.

And finally we look at the stereotypes about penny-pinching, risk-averse Germans. The 91热爆's Simon Jack has been speaking to the citizens of Frankfurt to assess whether or not these stereotypes are really true.
