Space cooling achieved by shading, natural (unassisted, as opposed to forced) ventilation, conduction control, radiation, and evaporation; also called passive cooling.

The cost of producing one additional unit of a product.

A unit of electricity consumption of one Watt over the period of one hour.

A device for measuring power consumption.

A device that transfers heat by the continuous evaporation and condensation of an internal fluid.

The average power output of a wind energy conversion system at a given mean wind speed based on a Raleigh frequency distribution.

The amount of kinetic energy gained by an electron when accelerated through an electric potential difference of 1 Volt; equivalent to 1.603 x 10

The ratio of a boiler's or gasifier's maximum output to its minimum output.

A device used to transfer heat from a fluid (liquid or gas) to another fluid where the two fluids are physically separated.

SMES technology uses the superconducting characteristics of low-temperature materials to produce intense magnetic fields to store energy. SMES has been proposed as a storage option to support large-scale use of photovoltaics and wind as a means to smooth ...

The difference between the total cooling effect and the dehumidifying effect.

A heat exchanger in which heat is recovered from the products of combustion.

A term generally applied to individual solar collectors, and typically to solar photovoltaic collectors or modules.

As a component of a heating or cooling appliance, rows of tubing or pipe with fins attached through which a heat transfer fluid is circulated and to deliver heat or cooling energy to a building.

The angle at which a solar collector or module is set to face the sun relative to a horizontal position. The tilt angle can be set or adjusted to maximize seasonal or annual energy collection.

Air that is taken from the outdoors.

An electrical device for converting alternating current to direct current. The chamber in a cooling device where water is separated from the working fluid (for example ammonia).

A popular term used to describe the increase in average global temperatures due to the greenhouse effect.

A machine for converting mechanical energy into electrical energy by magneto-electric induction; may be used as a motor.
