Electricity Today

  • Today we get power from converting primary sources like coal, natural gas, oil, nuclear, and other natural sources.
  • Generating electricity creates the most pollution out of any industry in the U.S.

  • They are non-renewable sources of energy meaning once we use them, they are gone and we cannot create more.
