Electricity is produced at a power plant by generating mechanical energy from sources such as coal, natural gas, nuclear fuel, or renewable energy sources such as wind or solar power.

The mechanical energy is used to turn a turbine, which is connected to an electrical generator. As the turbine turns, it causes the generator to spin, producing an electric current.

The current is then directed through power lines to the electrical grid, where it is distributed to consumers.

There are several different methods for generating electricity, and the specific method used depends on the availability of resources and the specific goals and requirements of the power plant.

For example, coal-fired power plants use steam turbines to generate electricity, while hydroelectric power plants use the force of falling water to turn the turbines.
