Final answer:
Coal power plants typically use steam turbines to generate electricity by converting the energy of steam, created by burning coal, into mechanical energy, which is then transformed into electrical energy. Option D is correct.
Step-by-step explanation:
Another way coal power plants produce electrical energy to power our homes, besides burning coal to generate steam, is by using steam turbines. The process involves combusting coal to produce steam, which then drives a turbine connected to a generator that produces electricity.
In essence, regardless of the initial energy source (coal, nuclear, wind, etc.), the majority of electrical generation systems work by spinning a turbine to generate electricity. This is achieved by passing a fluid (like steam) through the turbine, which then spins the axle connected to a loop of wire inside a generator, hence generating electricity.
Another way coal power plants produce electrical energy to power our homes is through steam turbines. In a coal-powered electric power plant, coal is burned in a boiler to produce steam. The steam then drives a turbine, which is connected to a generator that produces electricity.
