CAMBRIDGE, Mass. — The focus of clean-tech, or as well-known venture capitalist Vinod Khosla prefers to call it, “main-tech,” isn’t wind and corn ethanol. “It’s about the mainstream things we use in life and essentially reinventing society,” he says. Cleantech will impact technologies like engines, lighting, and refridgerators, which have markets worth hundreds of billions of dollars.

Khosla has invested in a number of companies exploring more energy-efficient technologies. “Almost any area you look at, there’s so much innovation going on…The list is endless,” he says.

Andy interviewed Khosla on the MIT campus yesterday, where Khosla delivered a keynote speech about energy and clean-tech at the MIT Technology Review EmTech08 conference. Martin LaMonica at CNET has a report on the speech at CNET.
