 Island powered solely by RenewablesMar 27, 2007 - DevelopmentCrossing.comMadrid's government announced Tuesday that El Hierro, one of the smallest of Spain's Canary Islands, is to receive 100 percent of its electricity supply from renewable energy sources. El Hierro will rely on a combination of hydroelectricity and wind power to generate its electricity. "El Hierro will be the first island in the world totally supplied by renewable energy," the ministry said. The technology associated with this task includes a system involving two reservoirs to power hydroelectric stations, a wind farm and a pumping system. "The bulk of the energy injected into the distribution network will emanate from the hydroelectric plant" with capacity of 10 megawatts, the ministry said. The wind farm will generate electricity for the pumping station that will pump water to the two reservoirs that feed the hydroelectric stations, the ministry explained.
