Possible Version:

　　Dear friends,

　　As is known to all, owing to the lack of resources and the increase of population, we have suffered the shortage of electricity in East China in the last few years. And now, summer, in which a large amount of electricity will be badly needed, is just around the corner.

　　We are all familiar with the effects brought by the power cut. Our work is interrupted frequently and we have to do things by the light of candles, which is harmful to our eyes. At home, we have to stay in the darkness doing nothing in the evening. So everyone in our neighbourhood shall not neglect this solution--saving electricity. Besides the efforts made by the government, there‘re more we can and should do, like using the air-conditioner less often, turning off the light upon leaving, reminding family members of the importance of saving electricity and so on.

　　As a saying puts, " Actions speak louder than words", please join in the action to save electricity, from yourself, from now on. Action!
