Obama pledges billions to develop clean energy

President Obama is ramping up efforts to promote clean energy. He's made repeated speeches on the topic, and in the last month, he's pledged $10  billion in federal loan guarantees for solar, wind and nuclear power as well as energy-efficient windows.

On Friday [March 5] , Energy Secretary Steven Chu announced $117 million in loan guarantees to help build a 30-megawatt wind energy project in Kahuku, Hawaii, and $72 million to Minnesota-based Sage Electrochromics [Faribault, Minn.] to build a 250,000-square-foot facility to make electronically tintable, energy-saving glass.

These loan guarantees follow $8.3 billion offered last month to help build two new nuclear power reactors in Georgia and $1.4 billion to create the world's largest solar complex in California's Mohave Desert, according to a March 6 USA Today report.
