LOOKING
TO THE FUTURE: Solar Thermal Electricity
Two different renewable technologies harvest solar radiation
in order to generate electrical energy. Solar thermal technology
uses mirrors to concentrate the sun's heat. The heat
is used to drive either a steam turbine or a gas piston.
The moving turbine or piston has a magnet attached, which
moves through a coil and generates an electric current. Solar
thermal energy is a large-scale application, used by a power
plant in place of nuclear or fossil fuels.
