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.

Many people still believe that natural resources will never be used up. Actually, the world's energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically try to find out alternative sources of power. According to Professor Ma Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power the only alternative.
However, many people do not approve of using nuclear power because it is very dangerous. What would happen if there were a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations.
The most effective thing is that we should use natural resources as economically as possible.
