Energy The Invisible Power

Welcome to our Energy page. Energy is the invisible power that allows people, machines and animals, move or work.

• Fossil fuels coal, gas and oil, have been in the ground for millions of years and once they have been used up we can not replace them.
• It can heat things up or cool things down.
• It can make sound and light.
• Electricity can be made from wind, water and sunlight. We can also make electricity from nuclear energy as well.
  
• The earth’s energy comes from the sun, even though it is 150 million kilometres away.
• Every time you see a bus, car, plane, train or boat moving, they are using energy usually in the form of oil, gas or coal.
• Energy is released from these when they are burned.
  
• Solar energy is renewable and can be replaced because solar means powered by the sun.
• Wind energy from wind farms, is a natural source which is not harming the fossil fuels and they will not run out. Wind farms have large windmills called turbines.
  
• Water energy is another natural source. It is captured by using waves and the tide in the sea, to
  produce energy.
• This is why we should be using as much wind and solar energy as possible, as it is from a natural source that can be used over and over again.
• Coal has come from plants that have rotted millions of years ago, and then dug out of the ground.
  
• Nuclear Energy comes from special metals in rocks. They are dug up, and the special metal splits into tiny pieces called atoms; these release energy.
• Oil and Gas come from tiny animals and plants (fossils) which died millions of years ago. They have all been squashed together into rocks which have to be drilled out.
• Food is also a fuel, from which humans and animals gain energy.
