| 3753777583 | energy carrier | something that can move and deliver energy in a convenient, usable form to end users | 5 | |
| 3753777584 | turbine | a device with blades that can be turned by water, wind, steam, or exhaut gas from combustion that turns a generator in an electicity producing plant | 6 | |
| 3753777585 | electrical grid | a network of interconnected transmission lines that joins power plants together and links them with end users of electricity | 7 | |
| 3753777586 | combined cycle | a power plant that uses both exhaust gases and steam turbines to generate electricity | 8 | |
| 3753777587 | capactiy | in reference to an electricity generation plant, the maximum electrical output | 9 | |
| 3753777588 | capacity factor | the fraction of time a power plant operates in a year | 10 | |
| 3753777589 | cogeneration | the use of a single fuel to generate electricity and to produce heat | 11 | |
| 3753777590 | coal | solid fuel formed primarily from the remains of trees, ferns, and other plant materials preserved 280 million to 360 million years ago | 12 | |
| 3753777591 | petroleum | a fossil fuel that occurs in underground deposits, composed of a liquid mizture of hydrocarbons, water, and sulfur | 13 | |
| 3753777592 | crude oil | liquid petroleum removed from the ground | 14 | |
| 3753777593 | oil sands | slow flowing, viscous deposits of bitumen mized with sand, water, and clay | 15 | |
| 3753777594 | bitumen | a degraded petroleum that forms whe petroleum migrates to the surface of Earth and is modified by bacteria; aka tar or pitch | 16 | |
| 3753777595 | CTL (coal to liquid) | the process of converting soild coal into liquid fuel | 17 | |
| 3753777596 | energy intensity | the energy use per uit of gross domestic product | 18 | |
| 3753777597 | hubbert curve | a bell shaped curve representing oil use and projecting both when world oil production will reach a maximum and when we will run out of oil | 19 | |
| 3753777598 | peak oil | the point at which half the total known oil supply is used up | 20 | |
| 3753777599 | fission | a nuclear reaction in which a neutron strikes a relatively large atomic nucleus, which then splits into two or more parts, releasing additional neutrons and energy in the form of heat | 21 | |
| 3753777600 | fuel rods | a cylindrical tube that encloses nuclear fuel within a nuclear reactor | 22 | |
| 3753777601 | control rods | a cylindrical device inserted between the fuel rods in a nuclear reactor to absorb excess neutrons and slow or stop the fission reaction | 23 | |
| 3753777602 | becquerel (Bq) | unit that measures the rate at which a sample of radioactive material decays; 1 Bq = decay of 1 atom or nucleus per second | 24 | |
| 3753777603 | curie | a unit of measure for radiation; 1 curie = 37 billion decays per second | 25 | |
| 3753777604 | nuclear fusion | a reaction that occurs when lighter nuclei are forced together to produce heavier nuclei | 26 |
