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

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

A unit or measure of solar radiation; 1 calorie per square meter or 3.69 Btu per square foot.

A type of solar thermal collector in which a heat transfer fluid drips out of header pipe at the top of the collector, runs down the collector absorber and into a tray at the bottom where it drains to a storage tank.

The power output of a device under specific or nominal operating conditions.

The change in the power available in the wind due to changes in the windspeed or velocity profile; the windpower profile is proportional to the cube of the wind speed profile.

The electrical and magnetic fields created by the presence or flow of electricity in an electrical conductor or electricity consuming appliance or motor.

The process of implementing measures to reduce peak power demands on a system.

A product of crude oil that is used for space heating, diesel engines, and electrical generation.

The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. One watt equals 1/746 horsepower, or one joule per second. It is the product of Voltage and Current (amperage).

A discontinuance of electric power supply.

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 ...

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

The compound (working fluid) used in air conditioners, heat pumps, and refrigerators to transfer heat into or out of an interior space. This fluid boils at a very low temperature enabling it to evaporate and absorb heat.

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

A device that uses electronic components to regulate the voltage of fluorescent lamps.

An index that combines sensible temperature and air humidity to arrive at a number that closely responds to the effective temperature; used to relate temperature and humidity to levels of comfort.

A sinusoidal quantity having a frequency that is an integral multiple of the frequency of a periodic quantity to which it is related.

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

The cost of producing one additional unit of a product.
