The sun is the answer
Solar power is the conversion of sunlight into energy and is by far the world’s most available energy source. it is a renewable fuel and eco-friendly. Because solar power depends on lots of sunshine, it is not surprising that Spain, one of the sunniest countries in solar energy development and is the world’s fourth manufacturer of solar power technology.
Europe’s first solar power tower plant was opened in the Spanish city of Seville in 2007. The 11- megawatt solar power tower produces electricity from the sun using 624 large movable mirrors called heliostats. Each of the mirrors concentrates the sun’s rays to the top of a 115 meter-high tower. In the tower there is a steam turbine that drives a generator to produce electricity.
Spain has also been a pioneer in photovoltaic technology, which converts sunlight directly into electricity. Since the 1990s many photovoltaic plants has been opened throughout the country. In 2010 Spain was able to generate twelve per cent of all power consumed from renewable energy, most of this from solar power. This percentage is likely to double in the next decade.
