Solar energy is the utilization of the radiant energy from the Sun. Solar power is often
used interchangeably with solar energy but refers more specifically to the conversion
of sunlight into electricity, either by photovoltaic and concentrating solar thermal
devices, or by one of several experimental technologies such as thermoelectric
converters, solar chimneys and solar ponds.
Solar energy and shading are important considerations in building design. Thermal
mass is used to conserve the heat that sunshine delivers to all buildings. Daylighting
techniques optimize the use of light in buildings. Solar water heaters heat swimming
pools and provide domestic hot water. In agriculture, greenhouses expand growing
seasons and pumps powered by solar cells (also known as photovoltaics) provide
water for grazing animals. Evaporation ponds are used to harvest salt and clean waste
streams of contaminants.
Solar distillation and disinfection techniques produce potable water for millions of
people worldwide. Simple applications include clotheslines and solar cookers which
concentrate sunlight for cooking, drying and pasteurization. More sophisticated
concentrating technologies magnify the rays of the Sun for high-temperature material
testing, metal smelting and industrial chemical production. A range of prototype solar
vehicles provide ground, air and sea transportation.
