How do power plants generate electricity?

How do power plants generate electricity?

Thermal Power Plants generate electricity by converting heat into electricity, essentially by burning a fuel. A coal power plant works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine.
