Energy Choices & Security (SL IB Environmental Systems & Societies (ESS))

The figure below shows a prediction for energy use per person in different parts of the world in 2030.

Explain why some parts of the world use large amounts of energy per person.

One possible short term solution to the global energy crisis is to extract shale gas. Shale gas is natural gas trapped in the rocks underground. This gas can be extracted by a process called fracking. In places where fracking has been done, there is some evidence that it can cause minor earthquakes. Because shale gas is natural gas (methane), it is a fossil fuel.

Another possible solution is to build more nuclear power stations. Nuclear power stations use fission to generate electricity.

Evaluate the two solutions outlined above and give a conclusion.
