A fluid used to absorb and transfer heat energy.

Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature.

The power output of a device under specific or nominal operating conditions.

A device that transfers heat by the continuous evaporation and condensation of an internal fluid.

A structure or media that absorbs heat.

This committee has jurisdiction on: coal production, distribution and utilization; energy policy; energy research, conservation, and development; hydroelectric power; irrigation; mineral conservation; nonmilitary development of nuclear energy; solar energ ...

The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. One watt equals 1/746 horsepower, or one joule per second. It is the product of Voltage and Current (amperage).

For valves and fittings, implies that they are suitable for working pressures between 125 to 175 pounds per square inch.

The electrical and magnetic fields created by the presence or flow of electricity in an electrical conductor or electricity consuming appliance or motor.

A discontinuance of electric power supply.

A product of crude oil that is used for space heating, diesel engines, and electrical generation.

An index that combines sensible temperature and air humidity to arrive at a number that closely responds to the effective temperature; used to relate temperature and humidity to levels of comfort.

A device that uses electronic components to regulate the voltage of fluorescent lamps.

The compound (working fluid) used in air conditioners, heat pumps, and refrigerators to transfer heat into or out of an interior space. This fluid boils at a very low temperature enabling it to evaporate and absorb heat.

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.

A power source/generator that operates independently of or is not connected to an electric transmission and distribution network; used to meet a load(s) physically close to the generator.

The heat-transfer (exchanger) component of a heatpump, located outdoors, from which heat is collected in the heating mode, or expelled in the cooling mode.

Fuels that cannot be easily made or "renewed," such as oil, natural gas, and coal.

A sinusoidal quantity having a frequency that is an integral multiple of the frequency of a periodic quantity to which it is related.

The cost of producing one additional unit of a product.
