Our government is trying hard to build an energy-saving society. It is somebody’s duty to work hard and reach this goal. However, 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 off the tap after using it and have water running all the time. Our papers are primed on only one side, caused 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 forming the habit of turning off the tap immediate after using it What’s more, papers should not be printed on both sides and reused if possible. In a word, if everybody reduce the waste and takes action, we can contribute to our society.
