A number used to indicate gasoline's antiknock performance in motor vehicle engines. The two recognized laboratory engine test methods for determining the antiknock rating, i.e., octane rating, of gasolines are the Research method andthe Motor method. To provide a single number as guidance to the consumer, the antiknock index (R + M)/2, which is the average of the Research and Motor octane numbers, was developed.
Industry:Energy
The volume of natural gas withdrawn from reservoirs during the report year less:
*the volume returned to such reservoirs in cycling, repressuring of oil reservoirs, and conservation operations; less
*shrinkage resulting from the removal of lease condensate and plant liquids; and less
*nonhydrocarbon gases where they occur insufficient quantity to render the gas unmarketable.
Volumes of gas withdrawn from gas storage reservoirs and native gas, which has been transferred to the storage category, are not considered production. This is not the same as marketed production, because the latter also excludes vented and flared gas, but contains plant liquids.
Industry:Energy
Any material that has a limited capacity for conducting an electric current. Certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.
Industry:Energy
A system of transmission or distribution lines so cross-connected and operated as to permit multiple power supply to any principal point.
Industry:Energy
Any area that does not meet the national primary or secondary ambient air quality standard established by the Environmental Protection Agency for designated pollutants, such as carbon monoxide and ozone.
Industry:Energy
A component area of a Consolidated metropolitan statistical area consisting of a large urbanized county or cluster of counties (cities and towns in New England) that demonstrate strong internal economic and social links in addition to close ties with the central core of the larger area. To qualify, an area must meet specified statistical criteria that demonstrate these links and have the support of local opinion.

These interests entitle their owner(s) to a share of the mineral production from a property or to a share of the proceeds there from. They do not contain the rights and obligations of operating the property and normally do not bear any of the costs of exploration, development, and operation of the property.
Industry:Energy
A device that adjusts the amount of heating and cooling produced and/or distributed by automatically responding to the temperature in the environment.
Industry:Energy
Period of relatively low system demand.These periods often occur in daily, weekly, and seasonal patterns; these off-peak periods differ for each individual electric utility.
Industry:Energy
The volume of natural gas withdrawn from reservoirs less (1) the volume returned to such reservoirs in cycling, repressuring of oil reservoirs, and conservation operations; less (2) shrinkage resulting from the removal of lease condensate; and less (3) nonhydrocarbon gases where they occur in sufficient quantity to render the gas unmarketable. Note: Volumes of gas withdrawn from gas storage reservoirs and native gas that has been transferred to the storage category are not considered part of production. This production concept is not the same as marketed production, which excludes vented and flared gas.
