Explanation:
Electricity is produced at a an electric power plant. Some fuel source, such as coal, oil, natural gas, or nuclear energy produces heat. The heat is used to boil water to create steam. ... The spinning turbine interacts with a system of magnets to produce electricity
A standard 500 megawatt coal power plant produces 3.5 billion kWh per year, which is enough energy to power 4 million light bulbs all year. To power most of a household's electrical appliances for a year it would take around 4,750 pounds of coal
To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%
A power plant is an industrial facility that generates electricity from primary energy. Most power plants use one or more generators that convert mechanical energy into electrical energy in order to supply power to the electrical grid for society's electrical needs.
