It is used in power generation, primarily for
cooling thermal power plants; in the extraction, transport and processing of fuels; and, increasingly, in irrigation to grow biomass feedstock crops.
The production of wind energy also conserves water resources that would otherwise be used to
cool thermal power plants, something that is important in years when the province is hit by drought.
Not exact matches
When river or sea - water is used for
power plant cooling, it gets released back into the environment at a higher temperature, a problem known as
thermal pollution, which can affect aquatic organisms.
In return, the utility companies would not have to build
cooling towers on their Hudson River
power plants; they would instead regulate how the
plants were operated so as to minimize the fish kills, they would not be forced to follow the strict letter of the Clean Water Act, to use the «best available technology» to mitigate the fish kills caused by their
thermal pollution.
How much
cooling water does a nuclear
power plant need compared with coal, geothermal and solar
thermal plants (per MWh)?
90 percent of India's
thermal power plants — which provide the country with most of its electricity — rely on freshwater for
cooling.
Thermal power plants rely on water for
cooling, which means droughts can push generation offline.
In contrast, fossil fuels can have a significant impact on water resources: both coal mining and natural gas drilling can pollute sources of drinking water, and all
thermal power plants, including those
powered by coal, gas, and oil, withdraw and consume water for
cooling.
The
thermal energy not used by the
power plant is removed by
cooling water.
In contrast, for fossil - fired
plants to compensate for wind energyís
power fluctuations, the turbine has to heat up and
cool down, and the
thermal cycling shortens the turbineís life.
Water is another big concern — like any
thermal power generation (such as coal - or oil - fired, or even bio-mass-fired
plants) nuclear uses water for
cooling — and uses it in really massive quantities.
That means that any
thermal power plant could be increasingly hobbled by limited
cooling capacity.
