    Energy is becoming less and less. It is a problem in the world. Many people are worried about that there will be not enough energy for people to use if they use them in a wrong way.
    Most people agree that the problem can be solved (解决) in some ways. One is to save the energy. For example, some countries use daylight (目光) saving system (系统) instead of electricity for lighting. In other countries, if people use much electricity, water and farm land, they have to pay much for it.
    But only saving cannot solve the problem. There is another way, which is to develop new energy. People can develop much other energy such as nuclear power (核动力) and water power.
    If people do well in these ways, I believe people can solve these problems of energy and save much energy for themselves.
