- 4. remains of an ancient organism that is changed to coil, oil, or natural gas.
- 5. large piece of equipment that is used to generate power.
- 8. the splitting of an atom to produce electricity.
- 9. energy from a source that is replenished faster than it can be used up.
- 13. the type of cell that is used in solar panels. Uses selenium or silicon as the main material to make electricity.
- 14. the device that is used to capture wind energy to make electricity.
- 15. fuel used in nuclear fission reactors like those used at Brown's Ferry.
- 16. energy contained within the nucleus of an atom.
- 18. this material is captured as it sits usually directly above petroleum deposits deep in the Earth. Alabama has large platforms off the Mobile coast drilling for the substance.
- 19. the combining of atoms to produce electricity. Technology is still not completely developed.
Down
- 1. hard fossil fuel that is mined out of the ground and used in many power plants. Largest deposits are in the Eastern U.S.
- 2. this is the means of saving energy.
- 3. used in cars to produce electricity chemically by combining hydrogen with oxygen.
- 6. fuel that comes from plant material, manure, or other organic matter.
- 7. dams are used to capture moving water and then run the water through a turbine to make electricity.
- 10. oil that is pumped from the ground to the surface.
- 11. deposits that can be extracted profitably at current prices using current technology.
- 12. energy that is produced from the breakdown of elements in the soil.
- 17. heating that uses hard materials like rock, stone, and brick to store heat during the day and release it at night.
