A device or material with a high resistance to electricity flow.

Power plants, whose output depends on a factor(s) that cannot be controlled by the power generator because they utilize intermittent resources such as solar energy or the wind.

The process of converting municipal solid waste to energy and/or recovering materials for recycling.

A cooling device that uses mechanical energy to produce chilled water.

Ethyl alcohol (C2H5OH)

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

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

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 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 ...

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.

A type of combustion heating system in which combustion air is drawn directly from outside and the products of combustion are vented directly outside. These features are beneficial in tight, energy-efficient homes because they will not depressurize a home ...

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.

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

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

The temperature of the air as measured by a standard thermometer.

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

Any wholly or partially enclosed space in which combustion takes place.

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.

An automatic valve that is opened or closed by an electromagnet.

Turning off or disconnecting loads to limit peak demand.
