Solar fast track.

The federal government is carving out public land in Arizona, California, Colorado, New Mexico, Nevada and Utah for speedy development of commercial solar power plants. The goal is to have 13 solar power plants under construction by the end of 2010. The federal Bureau of Land Management has received applications for 158 solar projects on 1.8 million acres, which, according to federal estimates, are capable of generating 97,000 megawatts, enough to power 29 million homes.
