However, coal accounts for only 15% of European Union's energy production. In the 27 Member States, 53,000 persons are working in thermal power plants and in mines – 185.000, according to the European Commission. Mines in Germany and Poland are the most active, these being supported by modern technologies and improved working conditions.It usually requires mountain blasting and the removal of trees and plants in the mining area. Coal mining increases the risk of loosening top soils into streams and waterways and the sediments pollute our water and can smother plant life downstream and even kill fish. Coal has traces of sulfur and nitrogen.

Coal is a hard rock which can be burned as a solid fuel. It contains mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top. Peat, and therefore coal, is formed from the remains of plants that lived millions of years ago.According to the latest Reuters report, Botswana has commissioned a new 1.4 million tpy coal mine at the state-owned Morupule Coal Mine (MCM), with the aim of increasing exports.
