How does Ohio generate electricity?

Coal, a nonrenewable fossil fuel, is used to generate approximately 47 percent of the electricity in Ohio. Coal is burned to produce heat, which converts water into high-pressure steam. The steam turns the blades of a turbine that is connected to a generator. The generator spins and converts mechanical energy to electricity.
