SOLAR ENERGY

Solar energy is the cleanest and most abundant renewable energy source available. Modern technology can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use.

There are several ways to harness solar energy: 


  • Photovoltaic (also called solar electric).
  • Solar Heating and Cooling.
  • Concentrating Solar Power.


Advantages:


  1. Solar energy is free although there is a cost when build the panels and other equipment required to convert solar energy into electricity or hot water.
  2. Solar energy does not cause pollution.
  3. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.

Disavantages:


  1. Solar energy can only be harnessed when it is daytime and sunny.
  2. Solar collectors, panels and cells are relatively expensive to manufacture.
  3. Solar power stations can be built but they do not match the power output of similar sized conventional power stations. 

QUESTIONS:

What is your opinion of solar energy?
