Giant wind turbines dot the sky at sunset near Albacete, central Spain November 16, 2003. Spain is the world's second-largest producer of wind power after [Germany]. The growing renewable energy industry has created thousands of new jobs and the government projects wind power capacity will nearly triple by 2011 to help meet demand and reach Kyoto Protocol targets for reducing greenhouse gas emissions. Wind energy is captured through wind turbines that usually consist of three blades which rotate due to the air pressure exerted on them by strong winds which powers an electric generator that can be connected to a local utility grid or used alone.
