The Solar Energy Technologies program focuses on
developing cost-effective solar-energy technologies that have the
greatest potential to benefit our nation and the world. Solar
technologies diversify our energy supply, reduce our dependence on
imported fuels, improve air quality, and offset greenhouse gas
emissions. A growing solar industry also stimulates our economy by
creating jobs in solar manufacturing and installation.
CSP systems use reflective materials that
concentrate the sun's heat energy to drive a generator that produces
PV systems use semiconductor materials
that convert sunlight directly to electricity.
Solar collectors absorb the sun's energy
to provide low-temperature heat used directly for hot water or space
heating for residential or commercial buildings.
