Photovoltaic manufacturing capacity could reach 200 gigawatts (GW) globally by 2020

Robert W. Collins : scientist
Photovoltaics—the generation of electric power by direct conversion of sunlight using "solar cells"—is a rapidly growing field. Conservative estimates predict a worldwide annual photovoltaic manufacturing capacity of 200 gigawatts (GW) by 2020. For comparison, the current global generating capacity for commercial nuclear power plants is estimated to be 377 GW*. The United States currently has 8 percent of the manufacturing share of this market, but there are opportunities to double that or better, particularly through technological advances, according to the workshop report.
