We are looking for cheap, clean, and effective sources of energy. These types of energy won’t cause pollution or waste natural resources. It will be provided freely by the sun. One percent of the solar energy that reaches the earth will be enough to provide electricity for the whole population of the world. Solar energy will be used by many countries around the world. Solar panels will be placed on the roofs of houses and other buildings and the sun’s energy will be used to heat water. The energy will be stored for a long time. We hope that by using solar energy the problem of the energy shortage will be solved.
