Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature.

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

A device for measuring power consumption.

The cost of producing one additional unit of a product.

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

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 heat-transfer (exchanger) component of a heatpump, located outdoors, from which heat is collected in the heating mode, or expelled in the cooling mode.

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

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

A term applied to warm-air heating systems that deliver heated air to rooms by means of registers or baseboards located along exterior walls.

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

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

Energy available from the movement of the wind across a landscape caused by the heating of the atmosphere, earth, and oceans by the sun.

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.

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

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 measure of the percent of moisture actually in the air compared with what would be in it if it were fully saturated at that temperature. When the air is fully saturated, its relative humidity is 100 percent.

A building element that shades windows, walls, and doors from direct solar radiation and protects these elements from precipitation.

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 ...

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