1. work- the application of force through a distence.
2. energy- the capacity to do work.
3. power the rate of energy flow or the rate at which work is done.
4. joule- the amount of work done when a force of 1 newton is exherted iver 1 meter or 1 amp per second flow s through 1 ohm.
5. fossil fules- petroleum, natural gas, and coal which provide about 86% of all commerical energy.
6. proven reserves- have been mapped, measured and shown to be economically recoverable.
7.tar sands- liquid petrloium can be extracted from these sands with hot water chemicals or other stripping processes.
8.fuel assembly- pellets that are stacked into hollow metal rods and 100 of these rods bundeled together
9. neculear fission-splitting
10. control rods- are insterted into spaces between fuel assemblies yo shut down fission reaction.
11.high level waste repositroy- where burried deep in rge grouynd where it is hoped that they will remain unexposed.
12. monitered retreaviveble storage- holding waste underground mines where they can be watched.
13.nuclear fusion- energy relased when two smaller atomic nuclei fuse into one marger nucleus.
14. breeder reactors- produce fuel rather then consume it.
15. oil shale- fine grained sedimentary rock rich in soil orginc material kerogen.
16. secondary recovery techniques- methods of squeezing more oil from a reservoir
17. black lung disease- inflammation and fibrosis caused by acculumation of coal dust in the lungs or air ways.
