Work- The application of force through a distance; requires energy input
Joules- A unit of energy. One Joule is the energy expended in 1 second by a current of 1 amp flowing through a resistance of 1 ohm
Energy- The capacity to do work (that is, to change the physical state or motion of an object)
Power- The rate of energy delivery; measured in horsepower or watts
Watt- The force exerted by 1 joule, or the equivalent of a current of 1 amp per second flowing through a resistance of 1 ohm
Fossil Fuels- Petroleum, natural gas, and coal created by geological forces from organic wastes and the dead bodies of formerly living biological organisms
Carbon Capture And Storage (CCS)- Carbon dioxide (generally form fuel combustion and stored in geological formations
Peak Oil- A prediction, made about 1940 by Dr. M. King Hubbert, that oil production in the united states would peak in the 1970s and then decline
Tar Sands- Sand deposits containing petroleum or tar
Hydraulic Fracturing (Fracking) - A mixture of water, wand, and toxic chemicals is pumped into rock formations at extremely high pressure to fracture sediments and release oil or gas
Kerogen- A solid, energy-rich organic material similar to bitumen
Liquefied Natural Gas (LNG)- When natural gas (mostly methane) is cooled to approximately 162*C (-260*F) it becomes a colorless odorless liquid that takes up about 1/600th the volume of the gaseous state
Methane Hydrates- Small bubbles or individual molecules of methane trapped in a crystalline matrix of frozen water
Fuel Assembly- A bundle of hollow metal rods containing uranium oxide pellets; used to fuel a nuclear reactor
Nuclear Fission- The radioactive decay process in which isotopes split apart to create two smaller atoms
Chain Reaction- A self-sustaining reaction in which the fission of nuclei produces subatomic particles that cause the fission of other nuclei
Control Rods- Neutron-Absorbing material inserted into spaces between fuel assemblies in nuclear reactors to regulate fission reactions
Breeder Reactors- A nuclear reactor that produces fuel by bombarding isotopes of uranium and thorium with high-energy neutrons that convert inert atoms to fissionable ones
Nuclear Fusion- A process in which two smaller atomic nuclei fuse into one larger nucleus and release energy, the source of power in a hydrogen bomb
