Solar Power

Solar power is by far the Earth's most available energy source, and easily capable of providing many times the total current energy demand. The largest solar power plants, like the 354 MW SEGS, are concentrating solar thermal plants, but recently multi-megawatt photovoltaic plants have been built. Completed in 2008, the 46 MW Moura photovoltaic power station in Portugal and the 40 MW Waldpolenz Solar Park in Germany are characteristic of the trend toward larger photovoltaic power stations. Much larger ones are proposed, such as the 550 MW Topaz Solar Farm, and the 600 MW Rancho Cielo Solar Farm. Covering 4% of the world's desert area with photovoltaics could supply all of the world's electricity. The Gobi Desert alone could supply almost all of the world's total energy demand. Solar power is an intermittent energy source, meaning that solar power is not available at all times, and is normally supplemented by storage or by another energy source, for example with wind power and hydropower.
