This is possible as long as large quantities of fuel can be easily brought to the power plants.
Pollution is a major disadvantage of fossil fuels. Fossil fuel releases greenhouse gasses (GHG) carbon dioxide when burned thereby causing a greenhouse effect. This is also the main contributory factor to the global warming experienced by the earth today.
Power stations that utilize coal need large amounts of fuel. In other words, they not only need truckloads but trainloads of coal on a regular basis to continue operating and generating electricity.
