In our daily life, energy play a very important role, so we should save energy. I think there are many ways to save energy and now I will share with you some ways to save energy effectively. Firstly, we should turn off all the electric appliances when we don't use them such as: lights, fans, air conditioner...… Secondly, we can use solar energy or wind energy instead of electric energy in our house. It will help us save more money. Thirdly, we can go to school or go to work on foot, by bike or by public transport instead of motorbike or car. By these ways, the energy will be saved.

Energy is also not infinite. If the earth runs out of energy, then humans will lose life. Without energy, humans cannot function. So we need to use energy rationally and efficiently.
