Many people worry that energy resources on the earth will be exhausted if we use them in an unchecked way. And they believe that the energy shortage will cause serious problems and even crisis. Conserving energy is one of the measures which have been taken to solve the problem of energy shortage. For example, some countries have a daylight saving system to use less electricity for lighting. Also, some cities have enforced some facilities for saving water at public places such as rest rooms and bars. Still more, 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. In a word, it is high time that serious consideration was given to conserving energy. Only through immediate and effective action, can we human beings survive and enjoy life as desired.
