| hydroelectricity | is getting electricity from running water |
| water stored in a dam has | potential energy |
| when water is flowing it has | kinetic energy |
| wind turbines change | kinetic energy to electrical energy |
| nuclear fission uses | uranium |
| nuclear fusion uses | water |
| heat trapped beneath the surface of the earth contains | geothermal energy |
| biomass energy is energy obtained from | plants such as sugar cane |
