The type of primary fuel or primary energy flow that provides a power plant its primary energy varies. The most common fuels are coal, natural gas, and uranium (nuclear power).A substantially used primary energy flow for electricity generation is hydroelectricity (water). Other flows that are used to generate electricity include wind, solar, geothermal …
— There are five energy-use sectors, and the amounts—in quadrillion Btu (or quads)—of their primary energy consumption in 2023 were: 1; electric power 32.11 quads; transportation 27.94 quads; industrial 22.56 quads; residential 6.33 quads; commercial 4.65 quads; In 2023, the electric power sector accounted for about 96% of total U.S. utility …

To meet future energy demand growth and replace older or inefficient units, a large number of fossil fuel-fired plants will need to bebuilt worldwide in the next decade. Yet CO2 emissions from fossil-fired power generation are a major contributor to climate change. As a result, new plants must be designed and operated at highest efficiency.
Did you know? In 2003, 25% of electricity in Ontario came from burning coal. The last coal-fired power plant in Ontario closed in 2014.. What are fossil fuels?
