WHAT' HAPPENS TO ENERGY WHEN IT'S USED?

Energy never disappears, it can be transfromed from one type of energy into another, but it doesn't disappear completely.
Some common energy transformations:
  • Chemical energy: Aeroplanes and cars transform the chemical energy in fuel and petrol into kinetic and thermal energy.
  • Electrical energy: fans and electrical drills transform electrical energy into kinetic and thermal energy.
  • Light energy: Solar panels transfrom light eenrgy from the Sun into electrical energy during the day.
