Top 6 Things You Didn't Know About Solar Energy
Installing a concentrating solar power system in Gila Bend, Arizona. The curved  mirrors are tilted toward the sun, focusing sunlight on tubes that run the length of the mirrors. The reflected sunlight heats a fluid flowing through the tubes. The hot fluid then is used to boil water in a conventional steam-turbine generator to produce electricity. | Photo by Dennis Schroeder.
