As you know, energy is very important for our life and it is being run out more and more. I think we need to save energy because nobody can live without energy. Firstly, using less energy has lots of benefits – we can save money and help the environment. Energy production requires precious natural resources, such as coal, oil or gas. Therefore, using less energy will help us maintain these resources and make them last longer into the future. Secondly, we can change our means of transportation, if possible, we can walk or ride bicycle instead of taking the car. Finally, we save electricity by turning off all the appliances before going out or going to bed. Another way is to use energy saving light bulbs. Our electricity bill will be reduced by using this way. In short, saving energy is very necessary for our life in modern society. I think we should use them carefully because all of them are limited and they will be exhausted in the future.
