Electricity is generated using different sources of energy like coal, oil, hydro, nuclear, solar, biomass, etc. Coal, gas, diesel and naphtha are called thermal resources and the plants that operate on them are known as Thermal Power Plants (TPPs). It is understood that even as Renewable Energy (RE) will gain ground in the coming years and dependence on thermal sources - especially coal – must be reduced, they will play an important role in meeting the energy needs in the near future. How TPPs are set up and operated will have great environmental consequences.
