The total amount of electric energy loss in an electric system between the generation source and points of delivery.

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

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

The process of changing from one physical state (solid, liquid, or gas) to another, with a necessary or coincidental input or release of energy.

Classifications of fires developed by the National Fire Protection Association.

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.

As time increases from zero at the terminals of an inductor, the voltage comes to a particular value on the sine function curve ahead of the current. The voltage reaches its negative peak exactly 90 degrees before the current reaches its negative peak thu ...

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 device for measuring power consumption.

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

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 solar thermal system that has one tank for storing solar heated water to preheat the water in a conventional water heater.

Energy that comes from splitting atoms of radioactive materials, such as uranium, and which produces radioactive wastes.

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 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.

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).

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
