A large power plant that generates power for distribution to multiple customers.

A type of photovoltaic device in which the electricity induced in the cell is used immediately within the cell to produce a chemical, such as hydrogen, which can then be withdrawn for use.

The ratio of the electric power produced by a photovoltaic device to the power of the sunlight incident on the device.

The prevailing or average weather conditions of a geographic region.

A heat exchanger that transfers the heat contained in a liquid heat transfer fluid to air.

An air conditioning system that comes in two to five pieces: one piece contains the compressor, condenser, and a fan; the others have an evaporator and a fan. The condenser, installed outside the house, connects to several evaporators, one in each room to ...

The use of two or more different fuels (e.g. wood and coal) simultaneously in the same combustion chamber of a power plant.

A container that holds rock used as the thermal mass to store solar energy in a solar heating system.

The volume of a unit weight of a substance at a specific temperature and pressure.

The storage of compressed air in a container for use to operate a prime mover for electricity generation.

A type of High-Intensity Discharge (HID) lamp that uses sodium under high pressure as the primary light-producing element. These high efficiency lights produce a golden white color and are used for interior industrial applications, such as in warehouses a ...

Glass, plastic panels, or plastic sheets that reduce air infiltration and some heat loss when attached to either the interior or exterior of existing windows.

The generation of electricity or shaft power by an energy conversion system and the concurrent use of rejected thermal energy from the conversion system as an auxiliary energy source.

Consists of businesses that are not engaged in transportation or manufacturing or other types of industrial activities. Standard Industrial Classification (SIC) codes for commercial establishments are 50 through 87, 89, and 91 through 97.

The total amount of electricity produced by a power plant.

The low effective temperature of the sky on a clear night.

An instrument for measuring relative humidity by means of wet and dry-bulb temperatures.

The process of degrading organic material (biomass) by microorganisms in aerobic conditions.

A computer software program that simulates energy consumption of commercial buildings; used for design and auditing purposes.

A solar photovoltaic product that generally consists of groups of PV cells electrically connected together to produce a specified power output under standard test conditions, mounted on a substrate, sealed with an encapsulant, and covered with a protectiv ...
