On Power Failure
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 – 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.
