The maximum instantaneous wind speed (or velocity) that occurs within a specific period of time or interval.

Category:Energy Terms

A unit of pressure for a fluid, commonly used in water pumping and hydropower to express height a pump must lift water, or the distance water falls. Total head accounts for friction head losses, etc.

Category:Energy Terms

A coil of tungsten wire suspended in a vacuum or inert gas-filled bulb. When heated by electricity the tungsten "filament" glows.

Category:Energy Terms

The absolute centimeter-gram-second unit of force; that force that will impart to a free mass of one gram an acceleration of one centimeter per second per second.

Category:Energy Terms

An elementary particle of an atom with a negative electrical charge and a mass of 1/1837 of a proton; electrons surround the positively charged nucleus of an atom and determine the chemical properties of an atom.

Category:Energy Terms

The wheeling of electric power in amounts and at prices that generally have been negotiated in longterm contracts between the generator and a distributor or very large consumer of power.

Category:Energy Terms

The process of managing the consumption of energy, generally to optimize available and planned generation resources.

Category:Energy Terms

A mathematical representation of the frequency or ratio that specific wind speeds occur within a specified time interval.

Category:Energy Terms

The rate at which electricity is delivered to or by a system, part of a system, or piece of equipment expressed in kilowatts, kilovoltamperes, or other suitable unit, at a given instant or averaged over a specified period of time.

Category:Energy Terms

States that energy cannot be created or destroyed, but only changed from one form to another. First Law efficiency measures the fraction of energy supplied to a device or process that it delivers in its output. Also called the law of conservation of energ ...

Category:Energy Terms

The process of characterizing the wind resource, and its energy potential, for a specific site or geographical area.

Category:Energy Terms

One thousand kilowatts, or 1 million watts; standard measure of electric power plant generating capacity.

Category:Energy Terms

A pole used to assist in raising a tower.

Category:Energy Terms

An electricity powered device that extracts available heat from one area (the heat source) and transfers it to another (the heat sink) to either heat or cool an interior space or to extract heat energy from a fluid.

Category:Energy Terms

An electrochemical battery that uses lead and lead oxide for electrodes and sulfuric acid for the electrolyte.

Category:Energy Terms

The amount of heat introduced to a space from all heat producing sources, such as building occupants, lights, appliances, and from the environment, mainly solar energy.

Category:Energy Terms

A seal used to prevent the leakage of fluids, and also maintain the pressure in an enclosure.

Category:Energy Terms

A mainly flat surface for transmitting radiant energy.

Category:Energy Terms

A device where sunlight concentrated onto a absorber heats it to a high temperature, and the thermal radiation emitted by the absorber is used as the energy source for a photovoltaic cell that is designed to maximize conversion efficiency at the wavelengt ...

Category:Energy Terms

This designates the resistance of a material to heat conduction. The greater the R-value the larger the number.
