Solar Power Plants

Solar power, or energy from the sun, is by the earth's most abundant renewable energy source. Unfortunately, while having great potential, last year solar energy production accounted for only 0.02 percent of the world's energy consumption. With concern about global warming, however, governments are providing financial incentives for solar energy production, which helps to create demand and bring down the cost of solar energy technologies. Also, new approaches for solar energy production are being developed, such as that illustrated above where solar rays are concentrated in a single collecting mirror that allows for the building of large solar energy power plants. Examples of such solar energy power plants include the 46 MW Moura solar power plant in Portugal, the 40 MW Waldpolenz solar power plant in Germany, and the 11 MW PS10 solar power plant (illustrated above) in Seville, Spain.
