WHAT IS SOLAR ENERGY?
Energy from the sun can be categorized in two different ways:
- Thermal Energy (heat)
- Light Energy
Solar thermal technology uses the sun's heat energy to heat substances such as water or air for homes and businesses. The sun's heat can also be used to produce electricity by converting the sun's heat energy into mechanical energy.
Photovoltaics (PV) (photo=light, voltaics=electricity) is a semiconductor-based technology (similar to the microchip) which converts light energy directly into an electric current that can either be used immediately or stored, such as in a battery, for later use.

Solar energy technologies can provide electrical generation by heat engine or photovoltaic means, space heating in active and passive solar buildings; potable water via distillation and disinfection, space cooling by absorption or vapor-compression refrigeration, thermal energy for cooking, and high temperature process heat for industrial purposes. |
In the United States, heating, ventilation and air conditioning (HVAC) systems account for 30% of the energy used in commercial buildings and nearly 50% of the energy used in residential buildings. Solar heating, cooling and ventilation technologies can be used to offset a portion of this energy.
Solar energy may be used in a water stabilization pond to treat waste water without chemicals or electricity. A further environmental advantage is that algae grow in such ponds and consume carbon dioxide in photosynthesis.
