Non-Renewable Resources

What is a none-renewable resource?

 is a source of energy that cannot be replenished as it is used. 

What are examples of non-renewable resources?

• Fossil Fuels (Coal, Oil & Natural Gas): Chemical store of energy. 

• Nuclear Power: Energy from the structure of the atoms.

Explain the use of fossil fuels?

1. Fossil fuel is burnt, turning water into steam.

2. Steam rises past turbines and causes them to spin.

3. The turbines spin generators to generate electricity.

4. Transformers increase the voltage of electricity as it enters the National Grid.

5. Transformers decrease the voltage of electricity as it enters homes.

What are the advantages and disadvantages of fossil fuels?

Advantages	Disadvantages
Readily available	Will eventually run out
Relatively easy to produce energy from them	Increasing fuel costs
	Release CO2 (greenhouse gas) when burnt

Explain the use of nuclear power.

The process of a nuclear fission power reactor

What are the disadvantages and advantages of Nuclear power?

Advantages	Disadvantages
No release of carbon dioxide (CO2 ) – greenhouse gas	Non-renewable source – will eventually run out
No release of sulphur dioxide (SO2 ) – acid rain	Expensive to commission and decommission power stations
1 kg of uranium produces millions times more energy than 1 kg of coal	Hazardous radioactive waste produced
	Danger of release of radioactive materials into the environment
