Our government is trying hard to build an energy-saving society. It is somebody’s duty to work hard and reach this goal. Besides, not everybody has realized the important of it. Take our school for example. Sometime we can see that lights and computers are still on after class. Some students even forget to turn on the tap after using it and have water run all the time. Our papers are printed on only one side, which causing much waste. It’s time we did something to avoid this kind of waste. Firstly, make sure that all the light and other electric facilities turned off when we leave the rooms. Try to form the habit of turning off the tap immediate after using it. What’s more, papers should be printed on both sides and reused if possible.
