Without electricity, what would your life be like? You would have to find a way of ascending 15 floors with no elevator and preventing food in your refrigerator from spoiling. You could not watch television, warm your dinner up in the microwave, listen to your favorite music on the stereo, quickly dry your hair, cool down your bedroom by means of air conditioning, brighten that room with the touch of a switch or to operate essential machines like your dishwasher, washing machine and clothes drier. At night, your home would be dark and unsafe, and you would live deprived of the many time-saving technologies such as electric heaters, kettles, table lamps, videos and computers—which all make our life so much easier. On a larger scale, traffic, communications, transport, security systems, workplaces, water distribution, energy production, publishing and the press, all depend on electricity as well.
