Our government is trying hard to build the energy-saving society. It is everybody's duty to work hardly and reach this goal. But, not everybody has realized the importance of it. Take our school for an example. Sometimes we can see that light and computers are still on after class. Some students even forget to turn off the tap after using it and have water run all the time. Our papers are printed on only one side, causing more waste. It's time we did something to avoid this kind of waste. Firstly, make sure that all the lights and other electric facilities turned off when we leave the room. 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 reuse if possible.
