Thermal power generation is a leading "producer" of anthropogenic emissions in the atmosphere and soil, a major consumer of deficit-valuable natural resources (water and earth).

The combustion of coal in the boiler furnaces produces a significant amount of sulfur and nitrogen oxides and volatile solids constituting the fly ash.

The use of large volumes of water to dispose of the ash and slag and to maintain the appropriate water level of ash disposal pond to settle the slurry and clarify the return water alters the chemical and mineralogical composition of ground water in the area brings the pollution of groundwater and surface.
