Turning off or disconnecting loads to limit peak demand.

The amount of money required to secure a specified cash flow at a future date at a specified return.

The sum of the ratings of the electricity consuming apparatus connected to a generating system.

The highest wind speed at which a wind turbine stops producing power.

Waste water from a household source other than a toilet. This water can be used for landscape irrigation depending upon the source of the greywater.

Solar Two is a retrofit of the Solar One project (see above). It is demonstrating the technical feasibility and power potential of a solar power tower using advanced molten-salt technology to store energy. Solar Two retains several of the main components ...

A power plant that uses two thermodynamic cycles to achieve higher overall system efficiency; e.g.: the heat from a gas-fired combustion turbine is used to generate steam for heating or to operate a steam turbine to generate additional electricity.

The part of an energy utility's charge based on actual energy consumed by the customer; the product of the kilowatt-hour rate and the total kilowatt-hours consumed.

A method of controlling a wind turbine's speed by varying the orientation, or pitch, of the blades, and thereby altering its aerodynamics and efficiency.

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

An electric current taking a shorter or different path than intended.

A toilet that uses less water than a standard one during flushing, for the purpose of conserving water resources.

A type of inverter that produces square wave output.; consists of a DC source, four switches, and the load. The switches are power semiconductors that can carry a large current and withstand a high voltage rating. The switches are turned on and off at a c ...

The ratio of actual power being used in a circuit, expressed in watts or kilowatts, to the power that is apparently being drawn from a power source, expressed in volt-amperes or kilovolt-amperes.

A concrete pad that sits on gravel or crushed rock, well-compacted soil either level with the ground or above the ground.

The ability to dispatch power.

A solar collector in which the absorber is contained in a sealed glass tube, thereby providing for relatively high temperature heat gain.

A curve that displays load values on the horizontal axis in descending order of magnitude against the percent of time (on the vertical axis) that the load values are exceeded.

In reference to solar photovoltaic devices, the growth of one crystal on the surface of another crystal. The growth of the deposited crystal is oriented by the lattice structure of the original crystal.

The heat produced by combusting a specific quantity and volume of fuel in an oxygen-bomb colorimeter under specific conditions.
