John Doerr: The Promise and Profits of Greentech: TED 2007 Video

"I don't think we're going to make it," John Doerr proclaims, in an emotional talk about climate change and investment. Recently his daughter demanded he fix the mess the world is heading for. So he and his partners at Kleiner Perkins Caufield & Byers embarked on a greentech world tour -- surveying the state of the art, from the ethanol revolution in Brazil to Wal-mart's (!) eco-concept store in Bentonville, Arkansas. KPCB is investing $200 million in green technologies to save the planet -- profitably. But, Doerr fears, it may not be enough.
