Across
  1. 4. Electricity is generated from the energy that is released when the atoms of radioactive minerals are split (by nuclear fission) in nuclear reactors.
  2. 8. Energy harnessed from the movement of water through rivers, lakes and dams.
  3. 10. The movement of seawater in and out of a cavity on the shore compresses trapped air, driving a turbine.
  4. 11. Decaying plant or animal waste, which can be burned to provide energy, eg heat, or electricity.
  5. 12. A carbon-based liquid formed from fossilised animals.
Down
  1. 1. Energy from sunlight which is captured in solar panels and converted into electricity.
  2. 2. modern windmills turn wind energy into electricity.
  3. 3. In volcanic regions it is possible to use the natural heat of the earth.Cold water is pumped under ground and comes out as steam.Steam can be used for heating or to power turbines creating electricity.
  4. 5. tidal barrage (a kind of dam) is built across estuaries, forcing water through gaps.
  5. 6. Obtained from felling trees, burned to generate heat and light.
  6. 7. The movement of tides drives turbines.
  7. 9. Formed from fossilised plants and consisting of carbon with various organic and some inorganic compounds.
