When electricity travels through you, it is called an electric shock. It can be very painful and can even kill people. A bolt of lightning is electricity travelling from the clouds to the ground, or from cloud to cloud.
Some methods of generating electricity, like burning gas and coal, create greenhouse gases that cause climate change. People are trying to make more of our electricity in ways that are good for the environment , like using wind power or solar power.
Wind power generates electricity by using the wind to turn the big arms on a wind turbine. Solar power generates electricity by absorbing the heat and light from the sun in special panels. Electricity has led to a lot of changes in our lives. Before electricity, if you wanted to light your house at night, you had to use candles, or lamps filled with oil or paraffin.
In , the first electric streetlights in the world were put in London. In , Godalming in Surrey became the first town in the world to have an electricity supply that everybody in the town could use. Lots of trains are powered by electricity.
They either get it from a wire that runs over the tracks, or from a third rail. One of the reasons electricity changed our lives so much is that it can make things much more convenient. Before electric street lights, it was the job of some people to go around lighting the gas-powered lamps that towns used to have on their streets; they were called lamp lighters. Even though you can get small wind turbines to use at home, wind turbines have to be very big in order to make a lot of electricity.
Each blade on a big wind turbine could be as long as four double-decker buses! The best place to put a wind turbine is somewhere where there is a lot of wind to turn it. The more wind there is, the more electricity you can make. The best places often high up on a hill or on top of a tall building, but it can also be good to build wind turbines out at sea. Look through the gallery below and see if you can spot the following: An offshore wind farm off the coast of Kent This house uses solar power, and has solar panels on the roof A solar tower at a solar power plant in Spain A coal power station Sellafield nuclear power plant A cooling tower Pylons Clywedog dam in Wales Hoover dam in the United States A diagram showing how a battery works Low-energy light bulbs A standard light bulb.
