A power plant is a facility that generates electricity by converting various forms of energy. Common energy sources include coal, natural gas, nuclear, and renewable sources like solar and wind. The electricity produced is then transmitted through power lines to homes and businesses. Power plants can vary in size and type, depending on the energy source used. For example, a hydroelectric power plant uses flowing water to generate electricity, while a thermal power plant relies on heat from burning fuels. Each type plays a crucial role in meeting the energy needs of society.
