Across
  1. 2. the supply of energy that is in line with economic developments and environmental needs
  2. 3. an alcohol produced from plant matter such a sugar cane or maize which can be used as an alternative to petrol
  3. 7. a natural fuel such as coal, oil, or gas, formed in the
  4. 8. past from the remains of living organisms
  5. 9. form of energy produced by the tides or waves
  6. 11. form of energy that converts sunlight into electrical energy either
  7. 12. such as wind or solar energy. also known as an infinite resource or alternative energy
  8. 15. the reliable availability of energy sources at an affordable price with a consideration of the environmental impact.
  9. 16. photovoltaic (PV) panels or through mirrors that concentrate sunlight solar radiation.
  10. 17. from the formation of radioactive decay of material inside the earth. These underground reservoirs of steam and hot water can be tapped to generate electricity.

Down
  1. 1. resources that will run out and not be replenished by natural means on a level equal to consumption. also known as a finite resource. Example: oil, natural gas and coal
  2. 4. energy by the use of wind turbines to generate electricity.
  3. 5. fissures and extract oil or gas
  4. 6. a gas such as methane that can be used as a fuel and is produced by fermenting organic matter.
  5. 10. the energy released by nuclear reactions in the nucleus of atoms such as uranium or plutonium
  6. 11. rocks, boreholes, etc. so as to force open
  7. 13. systems that react promptly to sudden changes in supply-demand balance
  8. 14. HydroElectric Power; a form of energy generated by the
  9. 18. the process of injecting liquid at high pressure into
  10. 19. heat energy from the earth- geo (earth) + thermal (heat) which
