The economic crisis has left millions of people without jobs. But a portion of the stimulus law signed in February will invest in the clean energy sector, including provisions for new job creation. This could help jumpstart a proposed Clean Energy Corps.

The Corps would create green jobs in areas like weatherizing homes or building high-speed rail lines. But it would also focus on community service and technical training to combat global warming.

Van Jones founded Green For All, a national organization dedicated to building a green economy that helps lift people out of poverty. Green For All is one of more than 80 civic, labor, environmental and policy organizations that have endorsed the Clean Energy Corps idea.

The Corps would apply energy-efficient measures to over 15 million existing buildings -- from adding insulation to replacing inefficient boilers. According to the Clean Energy Corp alliance, just retrofitting buildings to be more green could create more than 600,000 new jobs.
