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.

Does NZ use coal to generate electricity?
no
Which type of coal is mainly used to generate electricity?

Why do we need coal to generate electricity?
Coal is used to generate electricity because it is a plentiful resource and has a high energy content, making it cost-effective for producing power. When burned in power plants, coal produces heat that is used to produce steam, which drives turbines to generate electricity. However, coal is a major source of greenhouse gas emissions and air pollution, leading to environmental concerns.
How coal is used to make electricity?
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.
Does coal 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.
What fuel does India use to generate electricity?
The fuel that India uses most to generate electricity is coal. Second to coal is hydro power and then natural gas resources.
How much coal does it require to generate 1000 KWH of electricity?
It takes one ton of coal to generate an average of 2500 KWH of electricity.
What fossil fuels do you burn to generate electricity?
mostly coal
