| Term | Definition |
|---|---|
| Active Solar Energy Systems | Solar energy systems that collects energy through the use of mechanical devices such as photovoltaic cells or flat-plate collectors |
| Biomass Fuel | Fuel that derives from plant material and animal waste |
| Breeder Reactor | A nuclear power plant that creates its own fuel from plutonium |
| Demand | The quantity of something that consumers are willing and able to buy |
| Fission | The splitting of an atomic nucleus to release energy |
| Fossil Fuel | An energy source formed from the residue of plants and animals buried millions of years ago |
| Fracking | The pumping of water at high pressure to break apart rocks in order to release natural gas |
| Fusion | Creation of energy by joining the nuclei of two hydrogen atoms to form helium |
| Geothermal Energy | Energy from steam or hot water produced from hot or molten underground rocks |
| Hydroelectric Power | Power generated from moving water |
| Nonrenewable Energy | A source of energy that has a finite supply capable of being exhausted |
| Passive Solar Energy Systems | Solar energy systems that collect energy without the use of mechanical devices |
| Photo Voltaic Cell | A solar energy cell usually made from silicon that collects solar rays to generate electricity |
| Potential Reserve | The amount of a resource in deposits not yet identified but through to exist |
| Proven Reserve | The amount of a resource remaining in discovered deposits |
| Radioactive Waste | Materials from a nuclear reaction that emit radiation |
| Supply | The quantity of something that producers have available for sale |
| Renewable energy | A resource that has a theoretically unlimited supply and is not depleted when used by humans |
| Acid Deposition | Sulfur oxides and nitrogen oxides, emitted by burning fossil fuels, that enter the atmosphere where they combine with oxygen and water to form sulfuric acid and nitric acid and return to earth's surface |
| Acid Precipitation | Conversion of sulfur oxides and nitrogen oxides to acids that return to Earth as rain, snow or fog |
| Air Pollution | Concentration of trace substances, such as carbon monoxide, sulfur dioxide, nitrogen oxides, hydrocarbons, and solid particulates, at a greater level than occurs in average air |
| Biochemical Oxygen Demand (BOD) | The amount of oxygen required by aquatic bacteria to decompose a given load of organic waste; a measure of water pollution |
| Chlorofluorocarbon | A gas used as a solvent a propellant in aerosols, a refrigerant and in plastic foams and fire extinguishers |
| Ecotourism | A form of tourism, based on the enjoyment of scenic areas or natural wonders, that aims to provide an experience of nature or culture in an environmentally sustainable way. |
| Greenhouse Effect | The anticipated increase in Earth's temperature caused by carbon dioxide trapping some of the radiation emitted by the surface |
| Nonpoint Source Pollution | Pollution that originates from a large, diffuse area |
| Ozone | A gas that absorbs ultraviolet solar radiation, found in the stratosphere about the Earth's surface. |
| Photochemical Smog | An atmospheric condition formed through a combination of weather conditions and pollution, especially from motor vehicle emissions. |
| Sanitary Landfill | A place to deposit solid waste, where a layer of earth is bulldozed over garbage each day to reduce emissions of gases and odors from the decaying trash to minimize fires and to discourage vermin |
