NPR business news starts with a new pulpit for Al Gore.
Former Vice President Al Gore has announced he's taking his climate change cause to Silicon Valley. He's been hired by one of the largest venture capital firms to work on green technology investments. The company - Kleiner, Perkins, Caufield and Byers - has already invested nearly $300 million in biofuel and solar companies. The idea is that Gore will help attract new clean technology companies and help guide them through the political process. Gore says he will donate his Kleiner salary to the environmental group Alliance for Climate Protection. He is expected to take a more active role than the firm's last big-name political hire, former Secretary of State Collin Powell.
