Solar Energy


The sun has produced energy from billions of years. Solar energy is energy from the sun in form of radiated heat and light. This energy can be converted onto other forms of energy such as heat and electricity.” In the 1830s, the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa.” To day people uses the sin for lots of things.

Solar energy can be converted to heat energy and used to:

  1. Heat water, which can be used in swimming pool, homes, building.
  2. Heat spaces inside greenhouses, homes and other buildings

Two may of converting solar energy to electricity in two ways.

  1. Photovoltaic (PV Device) or “Solar Cells” which changes the sunlight directing into electricity, and also used to power watches, calculators, and light road signs.
  2. Solar Power Plants, it can be used when the heat from solar thermal electors is used to hear a fluid which produces steam that is used to power generator.

The Solar energy havegot a lot of uses and I have wrote the most important ones and I may opinion it’s the best energy in this world.
