Solar Energy

Since we are starting solar energy tomorrow in class I searched for a video that would show solar power at work. I found one that highlighted a solar station in Southern Spain. There a large tower is surrounded by 600 solar mirrors that beam their light up to the top of the tower which can reach up to 400 degrees centigrade. When the sunlight is captured it is transferred into thermal energy. The steam created powers turbines like a normal generator and the heat can be stored for energy use at night when, obviously there is no light being produced from the sun. The most important aspect of the solar energy station is that no greenhouse gases are emitted. The project has plans to extend their amount of mirrors from 600 to thousands. It is even being considered to place a million mirrors across the Sahara Desert and sending the power to Europe. This again shows how many countries in Europe are way ahead of the United States in renewable energy. It just seems that the U.S is all talk and no action. There is no doubt that switching to renewables can be done, so what are we waiting for? http://www.youtube.com/watch?v=c9Uo3KlWNng
