Sources and Methods
Power plants creating electricity from fossil fuel.
Water as a cooling agent in industrial facilities.
Deforestation of the shoreline.
Soil erosion.
Effects
The residual heat released by power plants adds to the environment and impacts its inhabitants harshly.
Since hot water holds relatively less oxygen; many species in these habitats face difficulty in survival.
The cooling towers used in power plants release heat directly into the atmosphere, which raises the air temperature drastically, thus contributing to global warming .
Water heating due to thermal pollution alters marine ecology to a great extent; hotter water favors some species while it is harmful to others. In a similar way, during nuclear plant startup, shutdown for repair and maintenance and then sudden startup creates abrupt temperature changes in water contained in lakes. These thermal shocks can be lethal for certain aquatic species.
