We need energy to live and work. Our major source of energy is oil. Oil is one kind of fossil fuels. The amount of fossil fuels in the world is limited. Therefore, we must save it, and at the same time we must find new sources of energy. Geothermal heat and nuclear power are alternative sources of energy. They can give us electricity. Other alternative sources are the sun, the wave, and the water. These sources are not only unlimited and available but also clean and safe to the environment. People should develop and use them more and more in the future.                                                                                                    

1. What do we need energy for?                                                                                                                                                 →                                                                                                                                                                       

2. What is our major source of energy?                                                                                              →                                                                                                                             

3. Why must we save fossil fuels?                                                                                                 →                                                                                                                                                    4. What are the advantages of the other alternative sources of energy?                                       →                                                                                                                                   5.
