It transforms the kinetic energy from flowing water into electricity by using a turbine generator.

It uses large rotor blades, mounted at tall heights to convert the kinetic energy created by wind into electricity.

It uses photovoltaic cells to capture sunlight or electromagnetic radiation from the sun and convert it into electricity.

It produces electricity by burning organic materials in a boiler that produces high-pressure steam, which rotates a turbine generator to produce electricity.

Heat from the Earth's core boils underground reservoirs of water and convert it into steam for a turbine generator.

It produces electricity by harnessing the kinetic energy from the natural rise and fall of tides caused by the gravitational interaction between Earth, the sun, and the moon.
