You don't. But coal is an economical fuel. One method of producing electricity on a commercial scale is with steam. Coal provides an inexpensive source of heat to heat water to steam, which is directed through turbines which in turn drive generators. You can do the same thing with falling water (without the steam) if you have a large enough waterfall, or you can use a different heat source like natural gas or atomic energy. Coal is sometimes more economical.
Using coal to generate electricity. (APEX)
because it an fossil fuel
The coal is used mostly to generate electricity.
no
bituminous coal
Coal power stations burn coal to heat water to produce steam, which is then used to spin electricity turbines to generate electricity. The burning coal releases carbon dioxide.Wind farms have blades which turn in the wind to spin electricity turbines to generate electricity. There are no harmful carbon dioxide emissions.
Coal is used to generate almost half of all electricity produced in the United States. Besides electric utility companies, industries and businesses with their own power plants use coal to generate electricity. Power plants burn coal to make steam. The steam turns turbines which generate electricity.
Coal can't generate electricity by itself, but through the process of combustion, it can produce heat which can be used to produce steam that can run turbines which are connected to generators that produces electricity.
The fuel that India uses most to generate electricity is coal. Second to coal is hydro power and then natural gas resources.
Electricity is made by converting some form of energy into electricity. Coal is used to heat water in a boiler to make steam. The steam pressure rotates a turbine to power a generator.
It takes one ton of coal to generate an average of 2500 KWH of electricity.
