  2. Non-renewable Energy Resources • Fossil fuels • Nuclear power

  3. Fossil fuels How is it work? • Advantages: • Very large amounts of electricity can be generated in one place using coal, fairly cheaply. • Transporting oil and gas to the power stations is easy. • Gas-fired power stations are very efficient. • Disadvantages: • Basically, the main drawback of fossil fuels is pollution. • Burning coal produces more carbon dioxide than burning oil or gas. • Mining coal can be difficult and dangerous. Strip mining destroys large areas of the landscape. • Coal-fired power stations need huge amounts of fuel, which means train-loads of coal almost constantly.

  4. Nuclear power How is it work? • Advantages: • Nuclear power costs about the same as coal, so it's not expensive to make. • Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect. • Produces huge amounts of energy from small amounts of fuel. • Produces small amounts of waste. • Disadvantages: • Although not much waste is produced, it is very, very dangerous. • Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster.

  5. Renewable Energy Resources • Solar power • Wind power • Wave power

  6. Solar power How is it work? There are three ways the solar power can be used: Solar cell, Solar water heating, Solar Furnaces • Advantages: • Solar energy is free - it needs no fuel and produces no waste or pollution. • In sunny countries, solar power can be used where there is no easy way to get electricity to a remote place. • Handy for low-power uses such as solar powered garden lights and battery chargers, or for helping your home energy bills. • Disadvantages: • Doesn't work at night. • Very expensive to build solar power stations. • Can be unreliable unless you're in a very sunny climate.

  7. Wind power • Advantages: • Wind is free, wind farms need no fuel. • Produces no waste or greenhouse gases. • The land beneath can usually still be used for farming. • Wind farms can be tourist attractions. • A good method of supplying energy to remote areas. How is it work? • Disadvantages: • The wind is not always predictable - some days have no wind. • Suitable areas for wind farms are often near the coast, where land is expensive. • Some people feel that covering the landscape with these towers is unsightly.

  8. Wave power How is it work? • Advantages: • The energy is free - no fuel needed, no waste produced. • Not expensive to operate and maintain. • Can produce a great deal of energy. • Disadvantages: • Depends on the waves - sometimes you'll get loads of energy, sometimes almost nothing. • Needs a suitable site, where waves are consistently strong. • Some designs are noisy. But then again, so are waves, so any noise is unlikely to be a problem. • Must be able to withstand very rough weather.
