| Solar Energy |
Solar energy technologies have great potential
to produce clean energy. It can reduce our
dependence on imported fossil fuels and improve
the quality of the air we breathe, offset
greenhouse gas emissions. Here we explain 4 main
applications.
• Photovoltaics:
PV systems use semiconductor materials that
convert sunlight directly to electricity.
• Solar Thermal:
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.
• Concentrating solar power:
CSP systems use reflective materials that
concentrate the sun's heat energy to produce
steam to drive generator that produces
electricity and feed national electric grid.
• Solar Lighting:
Parabolic collectors focus sunlight into a fiber
optic system to illuminate building interiors
with sunlight. |
