| fossil fuels | coal, oil and natural gas are examples of this; made from ancient plants and animals under pressure for a LONG period of time |
| natural gas | a fossil fuel that does not cause acid rain |
| acid rain | caused by burning coal and oil; sulfur is emitted (released) which mixes with the water in the air and rains out someitmes 100's of miles away |
| global warming | caused by burning things once living such as fossil fuels and biomass; CO2 is released into the atmosphere and traps the sun's heat. |
| nuclear fission | splitting of uranium atoms, causing a chain reaction and generating heat to boil water in a power plant |
| radioactive | uranium is radioactive; radiation can cause cancer and genetic mutation so used uranium must be stored carefully |
| nuclear fusion | when atoms combine such as hydrogen and hydrogen making helium |
| geothermal | heat from the earth - molten rock |
| wind | movement of air created when the sun heats up air which rises above cold air |
| biomass | anything that was once living and is combustible (burnable) |
| gasohol | gasoline mixed with ethanol (alcohol) in order to save on fossil fuels |
| renewable | able to be replaced in a lifetime |
| nonrenewable | not able to be replaced within a lifetime |
| alternative energy resources | any resource that is not a fossil fuel |
| uranium | the fuel used in nuclear power; splitting creates heat |
| generator | a moving magnet within a coil of wire moves electrons in this device |
| hydroelectric power | electricity made by turning a turbine with water power from a river |
| turbine | a device similar to a wheel which when turned helps to move electrons |
| solar cells | made of silicon; light hits this panel moving electrons |
| thermal pollution | when the boiling water in a power plant has been used it needs to be cooled done. Sometimes the hot water goes into a river or pond. This harm to the wter is called... |
| Three Mile Island | This is the site of a nuclear disaster in 1979 in Pennsylvania |
| Chernobyl | This is the site of the worst nuclear melt down in history; in Russia |
| 10,000 years | nuclear waste remains radioactive for this long |
| geyser | an example of geothermal heat |
| peat | pre-coal, made from the remains of plants and animals underpressure |
