The United States in 2010 slipped to third in the world in the amount of private capital invested in the clean energy sector, according to a recent report by the Pew Charitable Trusts. The U.S. saw $34 billion in private equity invested in the sector last year, a 51 percent jump from 2009, but China received $54.4 billion, increasing the lead it’s held over the U.S. since 2008. Germany last year passed the U.S. with $41.2 billion invested in clean energy.
