Non-Renewable and Renewable Resources
Non-Renewable and Renewable Resources
Energy resources can be renewable or non-renewable.
Non-renewable
Non-renewable
- Non-renewable resources will run out one day.
- Fossil fuels and nuclear fuel are non-renewable.
- All non-renewable resources damage our environment.
Renewable
Renewable
- Renewable resources will never run out. They can be or are being replenished as they are used.
- Solar, wind, water waves, hydro-electricity, bio-fuel, tides, geothermal are renewable energy resources.
- Most resources damage the environment. But renewable sources are less harmful than non-renewable sources.
Uses of Energy Sources
Uses of Energy Sources
Heating and transport are two of the main uses of energy resources.
Transport
Transport
- Non-renewable:
- Petrol and diesel vehicles use fuel from oil.
- Some steam trains use coal for boiling water to produce steam.
- Renewable:
- Bio-fuels power some vehicles.
Heating
Heating
- Non-renewable:
- Natural gas is used to heat homes.
- Coal is burnt in fireplaces.
- Renewable:
- Some buildings are heated by geothermal heat pumps.
- These use geothermal energy resources.
- Solar water heaters use energy from the sun to heat water.
Changing Electricity Use
Changing Electricity Use
How people use energy in the UK has changed over time.
20th century
20th century
- Over the 20th century, electricity use increased in the UK because the population of the UK grew bigger.
21st century
21st century
- However, since the beginning of the 21st century, electricity use has been decreasing in the UK.
- This is because appliances are becoming more efficient.
- People are also becoming more concerned with how much energy they are using at home.
