Non-renewables — practice question

Fig. 4 shows a diagram of a coal mine. Fig. 5 presents a graph that gives data on the different non-renewable fuels used to generate electricity in Pakistan from 2006-11. The vertical axis is marked 'terawatt-hours (TWh)'. The key includes gas, oil, nuclear and coal. An article headed 'Energy crisis' says: 'Industrial growth in Pakistan relies on the availability of energy. Pakistan does not produce enough energy for its needs and therefore spends a lot of its earnings on expensive imports of fuels.'
