How does electricity get into the socket? Electricity is produced in power stations and transported to the cities using long power cables. It is then distributed to the houses by transformer stations and junction boxes. Next time you go for a walk, see if you can spot the junction boxes in your street! There are many ways of producing electricity and “loading” it into the power supply network, as power plant operators say.
More than half of the electricity produced in Germany, for example, is created using coal and natural gas. These high-energy materials are burned and the heat that is released is converted into electricity. A large amount of the additional electricity required is produced from uranium in nuclear power plants. It took millions of years to form our coal, oil and natural gas resources. If we measure this process against the length of a human lifetime, it would take too long to produce them again – and this is why we call them “non renewable” energy sources.
The renewable sources of energy include: Biomass – which is produced by using plants that grow again quickly – as well as sun, wind and water. Sunlight drives solar power plants, the wind powers windmills and the movement of water can also be used to produce electricity.
