| 6096737047 | Wind Power | The ability to make electricity using the air flows that occur naturally in the earth's atmosphere. Wind turbine blades capture kinetic energy from the wind and turn it into mechanical energy, spinning a generator that creates electricity. |  | 14 |
| 6096739337 | Biomass Energy | Organic material that comes from plants and animals, and it is a renewable source of energy. |  | 15 |
| 6096739338 | Geothermal Energy | Heat transferred from the earth's underground concentrations of dry steam, wet steam, or hot water trapped in fractured or porous rock |  | 16 |
| 6096740640 | Hydrogen Energy | A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. |  | 17 |
| 8465884293 | Fossil Fuel | A fuel derived from biological material that became fossilized millions of years ago. |  | 18 |
| 8465896068 | Nonrenewable Energy Resource | An energy source with a finite supply, primarily the fossil fuels and nuclear fuels. |  | 19 |
| 8465978758 | Turbine | A device with blades that can be turned by water, wind, steam, or exhaust gas from combustion that turns a generator in an electricity producing plant. |  | 20 |
| 8466044097 | Crude Oil | Liquid petroleum removed from the ground. |  | 21 |
| 8466057506 | Oil Sands | Slow-flowing, viscous deposits of bitumen mixed with sand, water, and clay. |  | 22 |
| 8466062470 | 2nd Law of Thermodynamics | When energy is changed from one form to another, it always goes from a more useful to a less useful form. |  | 23 |
| 8466070340 | Oil Pollution Act of 1990 | Gives the Environmental Protection Agency (EPA) the ability to respond to oil spills and to regulate oil storage facilities. | 24 | |
| 8466079332 | Radioactive Waste | Nuclear fuel that can no longer produce enough heat to be useful in a power plant but continues to emit radioactivity. |  | 25 |
| 8466103535 | Renewable Energy | An energy source that is either potentially renewable or nondepletable. | | 26 |
| 8466112798 | Biofuel | Liquid fuel created from processed or refined biomass. |  | 27 |
| 8466120845 | Biodiesel | A diesel substitute produced by extracting and chemically altering oil from plants. |  | 28 |
