With the development of our society， energy in the world bees more and morelimited， so it is quite important for us to save energy and to protect ourenvironment。 As a student， there are a lot of methods we can do to save energyat home。 For example， first， we can turn off the light as well as otherappliances when we are not using them。 Second， recycle the waste water， paperand other waste so that we can reuse them。 What's more， it is suggested to usepublic transportation more instead of private cars。
Above all， everyone can make a great contribution to our environment。 Ihope I can learn more to develop new and clear energy， like energy from the windand solar。
