Recently, every morning when I wake up, I find my air-conditioner automatically turned off . I didn't understand why at first, but soon I learned that there was a great shortage of electricity supply in our city C my air-conditioner turned off because of a power failure midnight.

　　With the rapidly developing industry and the ever-increasing population, demand for electricity supply is soaring. Besides, summers in recent years are much hotter than before, so most working places and households are air-conditioned, which consumes additional electricity.

　　Face with such a hard nut, we have to find ways to crack it . Above all, in western areas China, there is surplus of electricity supply. So, cities that are thirsty for electricity may ask for remote help. Then,when we have electricity, we should remember to save it . Set your air-conditioners at 27C and you won't feel less comfortable than when they are at 26C . In fact, some factories already shift their working hours to avoid the peak time of electricity consuming. My parents don't work from Monday to Friday as before C they work form Saturday to Wednesday and have the following two days off instead. This is also a way out, isn't it?
