The sun’s energy can be used to produce electricity, either through photovoltaic cells that convert sunlight directly into electricity, or by solar thermal collectors that convert water to steam which runs a turbine.
Solar technology today costs slightly more than traditional energy sources, but solar power has no fuel costs and no air emissions or waste and uses very little water. We are involved in several projects to help test and advance promising solar technologies because more can be done to improve the output and efficiency and help bring down the cost. Certain areas of the United States have more intense sun ideal for solar energy production. Xcel Energy is fortunate to operate in some of these areas.
