Coal is a black or black-brown sedimentary rock of organic origin that has the ability to burn, so it is used as a fossil fuel that is extracted from the earth by mining methods. It consists primarily of carbon and hydrocarbons, but also of other substances. Fuel and a source of electricity are very important. We have thermal power plants nearby and coal is sold for heating and selling sieve, there are several types of coal. If it's easy, everything is difficult.For example, in the USA, burning coal produces half of the required electricity, while in Serbia it participates in the total consumption of over 50%, while in the production of electricity it participates in energy with over 85% (in thermal power plants).
