It provides light. heat and power for us If we want to watch TV or films or to listen to the radios we also need it. Nobody can deny that the development of our civilization depends on electricity. If there were no electric power, our modem world would be in trouble. For one thing all the wheels would stop because the motors that power the machines would fail. For another, many, if not all, of our industries would cease production. All the world transport system, in addition. would be felt on the world’s communication systems. Thus our modern world would be impossible without electricity. Therefore, we should make better use of electric power.
