LOS ANGELES — Vinod Khosla, one of the world's most powerful venture capitalist, says in this video interview that the oil spill in the Gulf will spur innovation in clean energy development.

Former British Prime Minister Tony Blair has just joined Khosla Ventures as an adviser.  In this interview, Khosla speaks the former PM's role.

While a majority of investments of Khosla Ventures are in clean tech, it invests in several Internet start-ups including Hunch, YuMe, and Slide.

I interviewed Khosla yesterday at the Wall Street Journal's All Things Digital conference.
