Energy demands are increasing all the time. Approximately one third of the world’s population lives without electricity, relying solely on battery power and kerosene lamps and candles. These people’s governments want to supply them with electricity in order to improve their standard of living.
To provide electricity to all these people would mean building thousands of new power stations in order to greatly increase the current energy generating capacity. This would severely deplete the remaining supplies of fossil fuels, and send carbon dioxide emissions soaring out of control.
The way forward is to use renewable sources of energy that provide electricity without causing massive damage to the environment. At the same time, people will have to use fossil fuels more efficiently to ensure that the supply lasts as long as possible for example, by making cars travel further on a litre of petrol, and improving the efficiency of power stations.
