        One of the most important thing in our life is solar energy . The solar energy is the energy from the sun and to generate this energy you should use photovoltaic cell . There is three advantages of solar energy over energy made from fossil fuels . The first one is clean for example the solar energy did not pollute the air but the fossil fuels pollute the air . The second advantage is inexhaustible energy for example the solar energy does not finish but the fossil fuels is an exhaustible energy . The third one is the solar energy is free  for instant you can take the sun light with out pay any money but if you want the fossil fuels energy you should pay for it . In conclusion We should take the advantages and use the Sun light . We should build more and more of photovoltaic cell all over the world .
