The research work is an effort to find various impacts on the environment, ecosystem, life cycle, plants and animals for using coal. It is already declared by the reputed geologist and geo scientists of the world that coal should not be used anymore in the world even the rest coal lying under the earth should not be explored anymore. The characteristic of the world having cool weather, ecosystem, life cycle etc. are the result of having coal under the earth. Coal is considered as an integral part of the earth to manifest all these characteristics. When coal is explored, the earth loses a vital part of the earth which results a deviated character and at the same when the explored coal is burnt it makes the world more badly. If we go through the comparison table of pollutants emission by different fuel, we will see in quantity and type coal is worse emitter fossil fuel in the world. Especially a country like Bangladesh having an alluvial almost flat fertile land and with so many rivers, creeks, canals, it is quite likely that use of coal in any locations and plants will destroy the total lands including its environment and ecosystem. It is observed that a coal based power station is more dangerous in all respect. The coal based power station has much more environmentally harmful in comparison to any other power stations. So, Emission of CO2, NO2 and SO2 from coal based power station which causes acid rain and Greenhouse effect should not be operated anymore. However, to get remedy of this dangerous situation we can use Coal Bed Methane (CBM) and Underground Coal Gasification (UCG) process. Renewable energy is the best attempt to produce electricity to keep the world comfortable for human living. We should take effective plan to replace the fossil fuel based power generation by clean and renewable resources where Bangladesh has enormous quantity of renewable resources.
