Solar energy is produced from solar radiation. Sunlight travels through the upper parts of the earth's atmosphere. Once this sunlight reaches the surface of the earth, it must be captured so it can be turned into an usable energy source.
The largest group of geothermal power plants in the world is located at The Geysers, a geothermal field in California, United States. As of 2004, five countries (El Salvador, Kenya, the Philippines, Iceland, and Costa Rica) generate more than 15% of their electricity from geothermal sources.
