The average amount of solar radiation that reaches the earth's upper atmosphere on a surface perpendicular to the sun's rays; equal to 1353 Watts per square meter or 492 Btu per square foot.

A turbine that generates power from the combustion of a fuel.

The direct, diffuse, and reflected solar radiation that strikes a surface.

A load management objective that moves loads from on-peak periods to off-peak periods.

A smaller version of standard fluorescent lamps which can directly replace standard incandescent lights. These lights consist of a gas filled tube, and a magnetic or electronic ballast.

The value or purchasing power of a dollar that has not been reduced to a common basis of constant purchasing power, but instead reflects anticipated future inflation; when used in computations the assumed inflation rate must be stated.

To condition/cool air by dessication.

Materials that prevent or slow down the movement of heat.

A solar collector that uses reflective surfaces to concentrate sunlight onto a small area, where it is absorbed and converted to heat or, in the case of solar photovoltaic (PV) devices, into electricity. Concentrators can increase the power flux of sunlig ...

Transmit high-voltage electricity from the transformer to the electric distribution system.

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.

A smokestack or flue for exhausting the products of combustion from a combustion appliance.

That part of an electricity bill that is based on the amount of electrical energy consumed or supplied.

Technologies that pertain to the generation of electricity.

Standardized codes used to classify businesses by type of activity they engage in.

A small groove scribed into the surface of a solar photovoltaic cell which is filled with metal for contacts.

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 ...

A type of anaerobic digester that has a mechanical mixing system and where temperature and volume are controlled to maximize the anaerobic digestion process for biological waste treatment, methane production, and odor control.

The lowest wind speed at which a wind turbine begins producing useable power.

The physical process by which a liquid or solid is transformed into the gaseous state. For this process a mechanical device uses the outside air's heat to evaporate water that is held by pads inside the cooler. The heat is drawn out of the air through thi ...
