As you know our energy has limitation so we need to preserve it. I suggest some simple ways to save energy. Firstly, we should turn off all electric appliances at home when we don't use them, such as: fans, lights,... Secondly, we should turn off the faucets when we go out or have plumber check the water pipe regularly. Thirdly, we also save gas by preparing the ingredients well before turning on the gas stove to cook. Finaly, we should go to shcool on foot, by bicycle or use public transport to save oil and money. In short, saving energy is important for everyone.
