| fossil fuels | nonrenewable resource formed from the remains of plants and animals over millions of years. Produces carbon dioxide when burned. Examples: coal, oil, natural gas. |
| nonrenewable resource | a resource that forms at a rate much slower than the rate at which it is consumed |
| renewable resource | a natural resource that can be replaced at the same rate at which it is consumed. |
| insulation | a substance that reduces the transfer of heat |
| photovoltaic | solar energy that produces electricity |
| potential energy | stored energy and the energy of position |
| kinetic energy | motion of waves, electrons, atoms, molecules and substances |
| chemical energy | energy stored in the bonds of atoms and molecules. Fossils fuels, food, and batteries are examples |
| nuclear energy | energy stored in the nucles of the atom. Uranium is often used as fuel for nuclear fission (breaking of the nucleus) |
| gravitational energy | energy of place or position. Water behind a dam is an example |
| hydropower | Renewable energy from falling water or tides |
| radiant energy | light energy -- or solar |
| thermal energy | heat. Geothermal is thermal energy. |
| motion energy | energy from movement of a substance from place to place. Wind energy is an example. |
| electrical energy | Movement of electrons -- often generated by a magnet moving near a copper coil. |
| stored mechanical energy | Energy stored in objects by application of force. Compressed springs and stretched rubber bands are examples. |
| geothermal energy | Energy generated by using heat from magma near the surface of the earth. |
| biomass | energy generated from the burning of plants, wood, or agricultural waste. This is renewable but still produces carbon dioxide. |
| wind energy | Energy generated by spinning magnet inside a wind turbine. Renewable but only practical in some areas. |
| greenhouse effect | the atmosphere traps heat energy close to the earth; gases like carbon dioxide and methane are added to the atmospher by humans and increase this effect. |
