- At the moment, fossil fuels are relatively cheap and easy to obtain.
- Much of our infrastructure is designed to run using fossil fuels.
- Fossil fuels are non-renewable energy resources. Their supply is limited and they will eventually run out.
- Coal and oil release sulphur dioxide gas when they burn, which causes breathing problems and contributes to acid rain.
- When they are burnt they release carbon dioxide, which adds to the greenhouse effect and increases global warming.
