Energy shortage is a very serious problem in the world. Many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. This, most people agree, will cause serious problems and even crisis and jeopardize the survival of mankind . On the one hand, most people agree that the problem can be solved in one way or another. One is to conserve and save our energy. Energy refers not only to coal, oil, or natural gases but also to goods, land and water, etc. Most countries have realized the wastefulness in their using of energy. They are trying to conserve energy. For example, some countries have a daylight saving system to use less electricity for lighting. Some cities have enforced water savers at public such as restrooms and bars. Some have enforced serious penalties on overuse of electricity, water, and farming land. By these means, people hope the drain on energy resources could be slowed down. However, conservation alone cannot solve the problem. Another way, perhaps the best I think,, is to develop new energy resources. Obviously, no matter how hard we try to save energy resources and how abundant they are, we will use them up sooner or later. I think there are many energy resources that we can develop and utilize. We don t have to depend only on the current conventional energy resources. There are many other energy resources that we can develop such as nuclear power, waterpower and solar power. These resources, if developed, can completely replace the conventional energy and thus solve the problem of energy shortage.
