If the United States government is the largest energy consumer in the world, asks Nation contributing editor Christian Parenti, why doesn't it use its massive buying power to support real green, clean energy technologies--instead of subsidizing the catastrophic failures of oil giants like BP?

Parenti joins us in studio to point out that if the U.S. post office switched to electric cars, that subsidy alone would bring down the price and create infrastructure for the rest of the country. He also talks Bill Gates, more green technologies, and the war in Afghanistan.
