Where does electricity come from? Electricity comes from a power station in Larne called Ballylumford. It travels along long cables on big pylons. Then it reaches a smaller factory which transforms it into 132,000 volts. It keeps doing so until it reaches your home, school or work. Production of electricity. The effects on the environment Power stations use oil and coal or gas which pollutes the air. But some types of electricity do not pollute the air Renewable energy like Windmills Solar panels Hydroelectricity Nuclear is very clean too but it is very dangerous. Different types of energy Electricity can be changed into lots of different types of energy. Sound Movement Light Heat How to make a circuit You need 2 or 3 wires/1or 2 batteries/1 bulb.
