<h3>Write a short note on power plant.</h3>
Power plants are typically connected to a grid. In many power plants, a rotating device known as a generator is used to convert mechanical power into three-phase electric power. The movement of a conductor in relation to a magnetic field results in the creation of an electric current. The generator can be powered by a wide range of different energy sources. Most power plants across the world use fossil fuels like coal, oil, and natural gas to generate electricity. Examples of low-carbon power sources include nuclear energy and the rising use of renewable energy sources including solar, wind, geothermal, and hydroelectricity.
