  1. The Energy Crisis Our energy supplies are running out. We must think how to produce energy in the future.

  2. Everyone of us uses energy all day, every day!

  3. Most of our energy comes from burning fossilized fuel, such as coal, gas and oil.

  4. Fossilized fuel is running out and is polluting our world. We will need almost 60% more energy in 30 years. Oil experts estimate that we will use all our oil within the next 40 years!

  5. Imagine that you are running the country. What kind of energy would you use? Wind, sea, nuclear, solar, coal? Look at the different kinds of energy and then discuss your choices.

  6. Coal, gas and oil Oil experts estimate that we will have used all our oil within the next 40 years! Others say that we will discover more. a

  7. wind energy Wind energy on the land can provide valuable income to rural Wales, especially to farming communities in highland areas.

  8. sea energy The sea around the coast of Wales has the potential to produce plenty of electricity through harnessing the power of the tide, the current and the waves. Wales has strong currents in the sea and some of the highest tidal ranges in the world. Plans are being discussed for Swansea Bay, the Severn Estuary and Liverpool Bay.

  9. nuclear energy There are 16 nuclear power stations at present in Britain – each power station will close by 2023. The idea is that other renewable energy sources will displace nuclear power and will ease Britain’s dependence on fossilized fuel. However, at present the government are being advised to build more nuclear power stations if they are to meet the targets of greenhouse gas emissions. This picture shows the nuclear power station at Trawsfynydd in the Snowdonia National Park. It was shut down in 1993. The nuclear reactors are still kept within the building.

  10. different type of nuclear energy Nuclear power is usually created by splitting atoms (nuclear fission). Scientists are developing a new type of nuclear power which is very safe and combines atoms (nuclear fusion). There is plenty of fusion fuel available and it does not produce greenhouse gases when it ‘burns’. It is safe because it extinguishes when it malfunctions, and although radioactive materials are produced, they are not of a high level nor do they last for a long period of time. Fusion gives energy to the sun. Another 30 years is needed to develop nuclear fusion.

  11. solar energy Solar roof tiles use the sun’s light to create electricity or warm water. Houses with a lot of tiles can produce more electricity than is needed – the excess electricity could be sold back to local electricity companies.

  12. solar tubes Solar tubes reflect natural daylight through a tube into the home or office. They are a good means of saving energy during the day.

  13. natural light Saint Fagan’s ‘Green House’. The southern face of the house is glazed in order to take full advantage of solar energy.
