Solar power expected to account for 20% of U.S. electricity output by 2050
Solar energy has been used for generations, and solar-powered electricity was first produced in the United States in 1954. Solar energy is currently used to create electricity in two ways: photovoltaics (PV) and solar thermal. Solar PV cells, like those seen on rooftop solar panels, turn sunlight into electricity directly. Solar thermal facilities employ mirrors to focus sunlight at a central receptor, generating the high temperatures required for a steam-powered turbine to create energy.
