1. 1. ENERGY

2. 2. ENERGY The ability of a system to produce a change in itself or in the world around it. The ability to do work. Represented by the symbol E.

3. 3. WHERE DO WE GET ENERGY? Energy Resources.

4. 4. ENERGY RESOURCES Nonrenewable Resources Renewable Resources

5. 5. Nonrenewable Resources Any natural resource from the Earth that exists in limited supply and cannot be replaced if it is used up; also, any natural resource that cannot be replenished by natural means at the same rates that it is consumed.

6. 6. Example of Nonrenewable Resources Fossil Fuels Coal Oil Natural Gas Nuclear Energy

7. 7. Fossil Fuels Energy from fossilized organic materials. They are formed from the organic remains of prehistoric plants and animals. Example of which are: COAL OIL NATURAL GAS

8. 8. Coal Coal is crushed to a fine dust and burnt. Coal provides around 28% of our energy, and oil provides 40%. Mind you, this figure is bound to have changed since this page was written, so check the figures if you want to quote them. Burning coal produces sulphur dioxide, an acidic gas that contributes to the formation of acid rain. This can be largely avoided using "flue gas desulphurisation" to clean up the gases before they are released into the atmosphere. This method uses limestone, and produces gypsum for the building industry as a by-product. However, it uses a lot of limestone.

9. 9. Crude Oil (also called Petroleum) Crude oil (called "petroleum") is easier to get out of the ground than coal, as it can flow along pipes. This also makes it cheaper to transport.

10. 10. Natural Gas Natural gas provides around 20% of the world's consumption of energy, and as well as being burnt in power stations, is used by many people to heat their homes. It is easy to transport along pipes, and gas power stations produce comparatively little pollution.

11. 11. COMBUSTION

12. 12. In your group, discuss the ADVANTAGES and DISADVANTAGES of NONRENEWABLE ENERGY.

13. 13. 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. A fossil-fuelled power station can be built almost anywhere, so long as you can get large quantities of fuel to it. Didcot power station, in Oxfordshire, has a dedicated rail link to supply the coal.

14. 14. Disadvantages Basically, the main drawback of fossil fuels is pollution. Burning any fossil fuel produces carbon dioxide, which contributes to the "greenhouse effect", warming the Earth. Burning coal produces more carbon dioxide than burning oil or gas. It also produces sulphur dioxide, a gas that contributes to acid rain. We can reduce this before releasing the waste gases into the atmosphere.
