The most common way of producing electricity is by using fossil fuels. There are three main forms of fossil fuels: coal, oil and natural gas.

Once the fossil fuels are out of the ground, they are transported to the power plants. If oil is being used it usually first arrives in big tanker ships and then is transported to the plant along huge pipelines. Gas is transported by pipelines.

Another popular way to make electricity is with hydro power created from water stored in huge dams. The energy created by the water being released from these dams is transformed into electricity by hydroelectric turbines and generators.

Another way to make smaller amount of electricity is by chemical reaction like the ones that take place in batteries.

The chemicals in a battery react together and can produce an electrical charge. When the battery is placed into a circuit, we get a current of electricity (or the flow of energy!) that can be used to power whatever device it is hooked up to.
