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

A refined petroleum product suitable for use as a fuel in internal combustion engines.

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

The transmission of electricity through power lines.

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

A solar energy conversion device that uses a trough covered with a highly reflective surface to focus sunlight onto a linear absorber containing a working fluid that can be used for medium temperature space or process heat or to operate a steam turbine fo ...

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.

A pole used to assist in raising a tower.

A motor in which a three phase (or any multiphase) alternating current (i.e. the working current) is supplied to iron-cored coils (or windings) within the stator. As a result, a rotating magnetic field is set up, which induces a magnetizing current in the ...

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 ...

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

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

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.

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.

The quantity of heat produced to change a unit weight of a liquid to vapor with no change in temperature.

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

The regular periodic arrangement of atoms or molecules in a crystal of semiconductor material.

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.

The amount of solar radiation striking a surface per unit of time and area.

A device that captures the heat from the exhaust air from a building and transfers it to the supply/fresh fresh air entering the building to preheat the air and increase overall heating efficiency.
