We’ve just got back from Westfield, Stratford where British Gas hosted the finals of their exciting new Generation Green Energy Performance competition where schools competed to win an Energy Makeover, worth up to £150,000!
Six school classes were then chosen to dance on a special dance floor, made of tiles that converted their footsteps into electrical power!
Oh, and they got to dance with Jordan and Perri from Diversity!
To help you get thinking about energy, we’ve got some great pages all about it! Here’s the need-to-know stuff about the energy source, coal!
Coal is a form of rock that is usually black and hard, or black-brown.
How was it formed?
Around 300 million years ago the world was covered with tropical swamp forest. When these plants died they fell into the swampy earth and over time were buried. Over millions of years they were changed into coal by pressure from the layers of rock above them.
Where can you find coal?
Coal can be found in many places in the world. Some of the main sources include: China, India, USA, South America, Australia, Russia, Poland, Northern England, Scotland and Wales.
How is it made into electricity?
Coal is burned to heat water and produce steam. This steam propels the blades of a turbine. This is attached to a generator, which produces electricity.
What are the advantages of using coal?
- Coal is relatively cheap.
- It can be found in many places around the world.
- There are many coal reserves and there is plentiful supply.
What are the disadvantages of using coal?
- Coal is non-renewable. This means that one day we will run out of coal.
- Burning coal produces carbon dioxide gas. This is a greenhouse gas that contributes towards global warming.
- Burning coal can pollute the air
- Much of the coal we use in the UK must be imported
Competition is now closed.
