Solar energy is energy from the Sun in the form of radiated heat and light.

What ir does[]

It drives the climate and weather and supports life on Earth.

Solar energy technologies make controlled use of this energy resource.

Solar power is a synonym of solar energy or refers specifically to the conversion of sunlight into electricity by photovoltaics, concentrating solar thermal devices.



In building design, thermal mass is used to conserve heat, and daylighting techniques optimize light. Solar water heaters heat swimming pools and provide domestic hot water.

Solar distillation and disinfection techniques produce potable water for people residing there. Family scale solar cookers and larger solar kitchens concentrate sunlight for cooking, drying and pasteurization.


In agriculture, greenhouses grow specialty crops and photovoltaic-powered pumps bring water to grazing animals.


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.


Evaporation ponds find applications in the commercial and industrial sectors where they are used to harvest salt and clean waste streams of contaminants.

Types of technologies[]

Solar energy technologies utilize solar radiation for practical ends.
