Non-Renewable Energy

Fossil Fuels

  • Consist of: coal, natural gas, and petroleum
  • Natural gas was the largest source—about 40%—of U.S. electricity generation in 2022. It is used in steam turbines and gas turbines for electricity. 
  • Coal was the third-largest energy source for U.S. electricity generation in 2022—about 18%. Is used for heat and gas turbines that generate electricity 
  • Petroleum was the source of less than 1% of U.S. electricity generation in 2022. Also used in steam and gas turbines

Nuclear Energy 

  • Nuclear energy was the source of about 18% of U.S. electricity generation in 2022. Nuclear power plants use steam turbines to produce electricity from nuclear fission.
  • Nuclear fission is when certain radioactive atoms (like Uranium-235) are hit with an electron that separates the nucleus into two and releases energy and radioactive residue
  • Nuclear fusion is when atoms come together and release energy – this form is not invented yet.

Renewable Energy 

Geothermal: Harness the heat under earth’s surface to power turbines

Solar: Sun energy

Biomass : Burning trash to create energy

Hydro : Dams/ Water Energy

Wind: Wind energy

Hands On Activity:

  1. Pick one of the renewable energies and think of certain ways that they would fail.
  2. Once you have listed them down, draw and write about a design that would make the renewable energy more efficient. 
  3. Build Wind turbines and Test it Out!
