The greening of Silicon Valley

"IF THE best way to create the future is to invent it, we say the second-best way is to finance it." John Doerr is only half joking. He is one of the most influential venture capitalists in Silicon Valley, and he knows a thing or two about financing the future. But ask him what he's focused on now and you won't hear venture-capital buzz-phrases such as "Web 2.0". These days, Doerr is firmly focused on clean technology - and in particular, energy technologies that can save the planet from global warming.
