Effects of Conventional (fossil fuels & gas fired) power plants : Air pollution, Water Pollution, Land Degradation

Explanation:

Fossil power plants, that use fossil fuels for electricity generation, have various ill environmental effects

Air Pollution - Coal Power Plants emit many polluting gases into environment. Like Sulphur Dioxide, Carbon Monoxide etc, Nitrogen Oxides. The last gas is majorly emitted during process of nitrogen combustion.

Water Pollution - Coal washing process before placing it in boiler (for heat generated electricity) , circulates the same unclean water into water bodies & groundwater.

Land Degradation - The after process disposal mechanism implies untreated water & air pollutants released indiscriminately. This adversely effects the land quality & the wildlife.
