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.
