SOLAR ENERGY
Origin: solar energy is the sun’s rays
(solar radiation) that reach the earth. Solar energy can be
converted into other forms of energy, such as heat and
electricity.
Extraction:
solar energy can be converted to electricity in two ways:
Utilities:
solar energy is used to generate electricity and to power
watches, calculators and lighted road signs.
Additionally, solar energy can be converted to thermal (or
heat) energy and used to heat water for using in homes,
buildings, or swimming pools, and to heat spaces inside green
houses, homes, and other buildings. This is solar thermal
heat. It works with heating systems that require a collector
to absorb and collect solar radiation. Fans or pumps are used
to circulate the heated air.
Producer regions:
the most important producer regions of solar energy are United
States, Germany, Australia and Canada.
