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.

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

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

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

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

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

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.

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.

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

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

This committee has jurisdiction on: coal production, distribution and utilization; energy policy; energy research, conservation, and development; hydroelectric power; irrigation; mineral conservation; nonmilitary development of nuclear energy; solar energ ...

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

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

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

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