Solar Energy
More energy from the sun falls on the surface of the earth than all combined energy used by people. Solar energy is available in all regions of the planet, with some locational, temporal, and seasonal differences. This energy can be captured in a number of ways, including:
- Read about utilizing the sun's energy in passive solar design in buildings.
- Read about solar thermal devices which use the sun's energy to heat water.
- Read more about the solar photovoltaic cell, which converts solar energy into electricity.
