Electricity is one of the most important inventions ever. It is the thing that powers the Earth. If there was no electricity, we’d be back in the dark ages. Few people stop and think just how amazing electricity is. With the flick 1 of a switch 2, you can power almost anything. Think about what would happen if there was no electricity. We’d have no TV, no computers, no traffic signals 3. It would be like going back to living in caves. There are a few negative points about electricity, of course. Number one, it’s dangerous. Thousands of people die each year from electrocuting themselves or in electrical fires. And number two, it isn’t good for the environment. Most electricity comes from burning coal and that creates greenhouse 4 gasses.
