non renewable

4. Sands, Oil sands, crude bitumen, or more technically bituminous sands, are a type of unconventional petroleum deposit
5. Fuel, A fuel derived from biological material that became fossilized millions of years ago
6. , Solid fuel formed primarily from the remains of trees, ferns, and other plant materials preserved 280 million to 360 million years ago
8. Waste, Nuclear fuel that can no longer produce enough heat to be useful in a power plant but continues to emit radioactivity
9. renewable, Energy source that can be regenerated indefinitely as long as it is not overharvested
11. the radioactive decay/nuclear reaction of the nucleus of an atom that splits into smaller parts
14. A nuclear reaction in which a neutron strikes a relatively large atomic nucleus, which then splits into to or more parts, releasing additional neutrons and energy in the form of heat
15. , A unit of measure for radiation; 1 curie = 37 billion decays per second
17. Oil, The point at which half the total known oil supply is used up
18. , Fossil fuel occurring underground deposits, composed of liquid mixture of hydrocarbons, water and sulfur
19. Energy Resource, an energy source with a finite supply, primarily fossil fuels and nuclear fuels
21. Rod, A cylindrical tube that encloses nuclear fuel within a nuclear reactor

1. Oil, Liquid petroleum removed from the ground
2. a soft brown combustible sedimentary rock formed from naturally compresses peat; lowest rank of coal due to its relatively low heat content.
3. half-life, the rate at which a radioactive isotope decays
7. (Coal to Liquid), The process of converting solid carbon into liquid fuel
10. , A degraded petroleum that forms when petroleum migrates to the surface of the Earth and is modified by bacteria; also called tar or pitch
12. Fuel, Fuel derived from radioactive materials that give off energy
13. Rod, A cylindrical device inserted between the fuel rods in a nuclear reactor to absorb excess neutrons and slow or stop fission reaction
16. Fusion, A reaction that occurs when lighter nuclei are forced together to produce heavier nuclei
20. (Bq), Unit that measures the rate at which a sample of radioactive material decays (1Bq=decay of 1 atom or nucleus per second)
