| Question | Answer |
| Non-Renewable | Energy sources that, once they have been used, they can never be used again (finite) |
| Renewable | A natural source of power that will never run out (infinite) |
| Coal: Advantages | - It can generate large amounts of energy. -Mining coal is technically relatively easy and cheap. -World coal supplies would last another 200 years. -It is repetitively easy to convert coal into energy. |
| Coal: Disadvantages | -Burning coal releases harmful greenhouse gases into the atmosphere, causing air pollution. -Acid rain is produced when coal is burnt. -Deep shaft mining can be very dangerous. |
| Wind power: Advantages | -Its is a clean fuel and does not pollute or emit any greenhouse gases. -Wind turbines can be built on land and sea. -It's one of the lowest priced renewable energy source. |
| Wind Power: Disadvantages | -Energy is only produced when it's sufficiently windy. -Offshore turbines may disturb the migration pattern of birds. -Many people feel that wind turbines spoil the view. |
| Global Energy mix | -Continues to be dominated by non-renewable sources, with over 80%. -Predicted that the use of non-renewable sources could drop by approx 76% by 2020. -Current reliance on fossil fuels is a global concern. |
| Variations in Energy mix | Variations in energy mix can be dependent on a number of factors: -Population size - more population the greater demand for energy. -Income and wealth - Richer countries can afford to buy more energy. -Availability of energy resources. |
