This compound of nitrogen and oxygen is formed by the oxidation of nitric oxide (NO) which is produced by the combustion of solid fuels.

The products of all combustion processes formed by the combination of nitrogen and oxygen.

The effect of cooling by the radiation of heat from a building to the night sky.

The approximate energy producing capacity of a power plant, under specified conditions, usually during periods of highest load.

The price paid for goods or services at the time of a transaction; a price that has not been adjusted to account for inflation.

A class of power generator that is not a regulated utility and that has generating plants for the purpose of supplying electric power required in the conduct of their industrial and commercial operations.

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

A characteristic applied to domestic water heaters that is the amount of gallons raised 100 degrees Fahrenheit per hour (or minute) under a specified thermal efficiency.

Energy that comes from splitting atoms of radioactive materials, such as uranium, and which produces radioactive wastes.

An optical, ultrasonic, or infrared sensor that turns room lights on when they detect a person's presence and off after the space is vacated.

The space within a building or structure that is normally occupied by people, and that may be conditioned (heated, cooled and/or ventilated).

Energy conversion technologies that harness the energy in tides, waves, and thermal gradients in the oceans.

The process or technologies for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and that of ocean depths. Warm surface water is pumped through an evaporator containing a working fluid in a closed ...

In a given electrical circuit, the amount of current in amperes (i) is equal to the pressure in volts (V) divided by the resistance, in ohms (R).

A measure of the electrical resistance of a material equal to the resistance of a circuit in which the potential difference of 1 volt produces a current of 1 ampere.

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

Energy supplied during periods of relatively high system demands as specified by the supplier.
