  • NON-RENEWABLE FUELS
    • COAL
      • Coal is formed from fossilised plants. It can be found in seams either close to the surface or it has to mined from deep under the ground. It has to be burnt to produce energy.
      • ADVANTAGES
        • Coal supplies should last for another 250 years.
        • It is relatively easy to convert into energy by burning it.
        • It is relatively cheap to mine.
      • DISADVANTAGES
        • Coal is bulky, and is therefore expensive to transport.
        • When burnt it gives off greenhouse gases, for example, carbon dioxide.
    • OIL
      • Oil is formed from fossilised animals. Lakes of oil are found under the land or sea trapped between seams of rock. Pipes are put down through the ground and the liquid is pumped to the surface. It is burnt to provide energy.
      • ADVANTAGES
        • Oil is relatively easy to convert into energy by burning it.
        • It is relatively cheap to mine.
        • Oil supplies should last for another 50 years.
      • DISADVANTAGES
        • When burnt it gives off greenhouse gases, for example, carbon dioxide.
        • Oil can be very expensive to buy.
    • NATURAL GAS
      • Methane gases are trapped between seams of rock under the Earth's surface. pipes are put down through the ground and the gas is pumped to the surface. It is burnt to provide energy.
      • ADVANTAGES
        • Gas is a cleaner fuel than oil or goal giving off fewer greenhouse gases.
        • Gas supplies should last for another 70 years.
        • Relatively easy to convert into energy by burning it.
      • DISADVANTAGES
        • Natural gas will not last forever.
    • NUCLEAR
      • Produced from uranium which is obtained by mining. Energy is produced when the atoms are split or joined together in nuclear reactors.
      • ADVANTAGES
        • It does not give off greenhouse gases.
        • Raw materials will last a long time.
        • A small amount of uranium gives off a lot of energy.
      • DISADVANTAGES
        • Nuclear reactors are expensive to build and run.
        • Nuclear waste is radioactive and highly toxic.
        • It has to be stored for 100s/1000s of years which is very expensive.

Clarity and accuracy make this mind map a good one to print out and familiarise yourself with the non-renewable energy types.

Hello,

I found this resource very helpful. However, at the edges, they seem to have cut off some information. Please could you help with this.

Thanks
