Non-renewable energy

Non-renewable energy is energy taken from "finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve", [1] as opposed to renewable energy sources, which "are naturally replenished in a relatively short period of time." [2]

  • Fossil fuels:
    • Coal exists as a mined solid.
    • Petroleum is a liquid, and forms the basis for heating oil, diesel fuel, and gasoline.
    • Natural gas is commonly also referred to just as gas. It is mostly methane, and most of the additional material is removed before use as a fuel.
  • Nuclear energy fuel for fission is mined as a solid as Uranium ore.
