Recently， every morning when I wake up， I findmy air-conditioner automatically¹ turned off . I didn't understand why at first ， but soon Ilearned that there was a great shortage² of electricity supply in our city – my air-conditionerturned off because of a power failure midnight.

With the rapidly developing industry and the ever-increasing population， demand forelectricity supply is soaring³. Besides， summers in recent years are much hotter than before ，so most working places and households are air-conditioned ， which consumes additionalelectricity.

Face with such a hard nut ， we have to find ways to crack it . Above all ， in western areasChina ， there is surplus⁴ of electricity supply. So ， cities that are thirsty for electricity mayask for remote help. Then ，when we have electricity ， we should remember to save it . Setyour air-conditioners at 27C and you won't feel less comfortable than when they are at 26C . Infact ， some factories already shift their working hours to avoid the peak time of electricityconsuming. My parents don’t work from Monday to Friday as before – they work form Saturdayto Wednesday and have the following two days off instead. This is also a way out， isn't it?
