Renewable Energy
By 2020, the UK hopes to use renewable energy resources to provide 15% of its total annual (yearly) energy. People are becoming more aware of how damaging fossil fuels are to the environment.
Government policy
Government policy
- Governments are introducing targets for renewable energy source use because of public pressure.
Power plants
Power plants
- Energy providers are building power plants that use renewable resources.
Vehicles
Vehicles
- Vehicle (car or lorry) makers are creating electric cars and hybrids.
Limits to Renewable Energy Resources
Limits to Renewable Energy Resources
Renewable energy resources have their limits. These include:
Reliability
Reliability
- Some energy resources (i.e. wind power) are less reliable than fossil fuels.
Cost
Cost
- Building renewable power plants is expensive.
- Renewable options (like hybrid cars and solar panels) are expensive.
Politics
Politics
- Some politicians may be less keen on renewable energy resources than others.
