688829726 | potential energy | Energy that is stored and held in readiness | |
688829727 | kinetic energy | the energy an object has due to its motion | |
688829728 | radiant energy | energy contained in light rays or any other form of radiation | |
688829729 | conduction | the direct transfer of heat from one substance to another substance that it is touching | |
688829730 | convection | the transfer of heat through a fluid (liquid or gas) caused by molecular motion | |
688829731 | energy quality | A measure of an energy's source's ability to do useful work. | |
688829732 | First law of thermodynamics | The principle of conservation of energy. Energy can be transferred and transformed, but it cannot be created or destroyed. | |
688829733 | Second law of thermodynamics | States that with each successive energy transfer or transformation in a system, less energy is available to do work. | |
688829734 | seam | a stratum of ore or coal thick enough to be mined with profit | |
688829735 | exploratory well | area drilled and sampled to determine if a fossil fuel reserve exists there | |
688829736 | proven reserve | The amount of a resource remaining in discovered deposits. | |
688829737 | crude oil | petroleum as it comes out of the ground and before it has been refined or processed into useful products | |
688829738 | shale oil | oil extracted from oil shale by heating | |
688829739 | tar sand | rock or sand layers that contain oil | |
688829740 | petroleum | an oily, dark-colored, flammable liquid found in the earth, consisting mainly of a mixture of various hydrocarbons. | |
688829741 | anthracite | a hard natural coal that burns slowly and gives intense heat | |
688829742 | bituminous coal | The most common form of coal; produces a high amount of heat and is used extensively by electric power plants. | |
688829743 | subbituminous coal | A grade of coal, intermediate between lignite and bituminous, that has a relatively low heat value and sulfur content. | |
688829744 | lignite | intermediate between peat and bituminous coal; produces little heat | |
688829745 | underground mining | involves the sinking of shafts to reach underground deposoits. In this type of mining, networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal. | |
688829746 | strip mining | proccess in which rock and soil are stripped from earths surface to expose the underlying materials to be mined | |
688829747 | overburden | the surface soil that must be moved away to get at coal seams and mineral deposits | |
688829748 | subsidence | the settling or sinking of a surface as a result of the loss of support from underlying materials, such as coal or water | |
688829749 | fly ash | a waste product produced by the burning of coal. | |
688829750 | vampire appliance | appliances that consume electricity, even when they are off; these are usually things that are still plugged into electricity and come on immediately (TVs, computers, etc.) | |
688829751 | acid mine drainage | Pollution caused when sulfuric acid and dangerous dissolved materials such as lead, arsenic, and cadmium wash from coal and metal mines into nearby lakes and streams. | |
688829752 | fission | the splitting of atoms which releases tremendous amounts of energy and is used to start the chain reaction of an atomic explosion | |
688829753 | nuclear fission | a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy | |
688829754 | breeder reactor | Nuclear fission reactor that produces more nuclear fuel than it consumes by converting nonfissionable uranium-238 into fissionable plutonium-239. | |
688829755 | half-life | the time required for one half of the atoms of a radioisotope to emit radiation an decay products | |
688829756 | fuel rod | a uranium rod that undergoes fission in a nuclear reactor | |
688829757 | NIMBY | "refers to the idea that, while people may be aware of the necessity of some unpleasant realities, such as prisons, landfills, or chemical plants, they insist theses place be located away from where they live"- NOT IN MY BACK YARD | |
688829758 | gasohol | a gasoline substitute consisting of 90% gasoline and 10% grain alcohol from corn | |
688829759 | biodiesel | A diesel-equivalent, processed fuel derived from biological sources (such as vegetable oils), that can be used in unmodified diesel-engine vehicles. | |
688829760 | hydroelectric power | electricity generated by flowing water | |
688829761 | fish ladder | a series of ascending pools providing a passage for salmon to swim upstream past a dam | |
688829762 | passive collection | Systems that do not make use of any externally powered, moving parts, such as circulation pumps, to move heated water or air. | |
688829763 | active collection | A type of system that uses circulating pumps and fans to collect and distribute heat. | |
688829764 | photovoltaic cells | Cells, usually made of specially-treated silicon, that transfer solar energy from the sun to electrical energy | |
688829765 | nacelle | the base of a windmill | |
688829766 | turbine | A machine for producing power in which a wheel or rotor is made to revolve by a fast-moving flow of water, steam, gas, or air. | |
688829767 | wind farm | a power plant that uses wind turbines to generate electricity | |
688829768 | geothermal energy | energy derived from the heat in the interior of the earth | |
688829769 | hydrogen cell | a cell that generates electricity from a controlled reaction between hydrogen and oxygen | |
688829770 | CAFE standards | Corporate Average Fuel Economy standards enacted into law in 1975, established fuel efficiency standards for passenger cars and light trucks. The fuel economy ratings for a manufacturer's entire line of passenger cars must currently average at least 27.5 mpg for the manufacturer to comply with the standard. |
