Term
ampere
Definition
A unit of measure for an electrical current; the amount of current that flows in a circuit at an electromotive force of one Volt and at a resistance of one Ohm. Abbreviated as amp.
Term
amp-hours
Definition
A measure of the flow of current (in amperes) over one hour.
Term
Appliance Standards
Definition
Standards established by the U.S. Congress for energy consuming appliances in the National Appliance Energy Conservation Act (NAECA) of 1987, and as amended in the National Appliance Energy Conservation Amendments of 1988, and the Energy Policy Act of 1992 (EPAct). NAECA established minimum standards of energy efficiency for refrigerators, refrigerator-freezers, freezers, room air conditioners, fluorescent lamp ballasts, incandescent reflector lamps, clothes dryers, clothes washers, dishwashers, kitchen ranges and ovens, pool heaters, television sets (withdrawn in 1995), and water heaters. The EPAct added standards for some fluorescent and incandescent reflector lamps, plumbing products, electric motors, and commercial water heaters and Heating, Ventilation, and Air Conditioning (HVAC) systems. It also allowed for the future development of standards for many other products. The U.S. Department of Energy (DOE) is responsible establishing the standards and the procedures that manufacturers must use to test their models. These procedures are published in the Code of Federal Regulations (10 CFR, Ch. II, Part 430), January 1, 1994 (Federal Register).
Term
ASHRAE
Definition
Abbreviation for the American Society of Heating, Refrigeration, and Air-Conditioning Engineers.
Term
ASTM
Definition
Abbreviation for the American Society for Testing and Materials, which is responsible for the issue of many standard methods used in the energy industry.
Term
Asynchronous Generator
Definition
A type of electric generator that produces alternating current that matches an existing power source.
Term
Audit (Energy)
Definition
The process of determining energy consumption, by various techniques, of a building or facility.
Term
Automatic (or Remote) Meter Reading System
Definition
A system that records the consumption of electricity, gas, water, etc, and sends the data to a central data accumulation device.
Term
Appliance Energy Efficiency Ratings
Definition
The ratings under which specified appliances convert energy sources into useful energy, as determined by procedures established by the U.S. Department of Energy
Term
Availability
Definition
Describes the reliability of power plants. It refers to the number of hours that a power plant is available to produce power divided by the total hours in a set time period, usually a year.
Term
Average Demand
Definition
The demand on, or the power output of, an electrical system or any of its parts over an interval of time, as determined by the total number of kilowatt-hours divided by the units of time in the interval.
Term
Average Cost
Definition
The total cost of production divided by the total quantity produced.
Term
Barrel (petroleum)
Definition
42 U.S. gallons (306 pounds of oil, or 5.78 million Btu).
Term
Baseload Capacity
Definition
The power output of a power plant that can be continuously produced.
Term
Baseload Demand
Definition
The minimum demand experienced by a power plant.
Term
Baseload Power Plant
Definition
A power plant that is normally operated to generate a base load, and that usually operates at a constant load; examples include coal fired and nuclear fueled power plants.
Term
Battery
Definition
An energy storage device composed of one or more electrolyte cells.
Term
Battery Energy Storage
Definition
Energy storage using electrochemical batteries. The three main applications for battery energy storage systems include spinning reserve at generating stations, load leveling at substations, and peak shaving on the customer side of the meter.
Term
Biomass Fuel
Definition
Biomass converted directly to energy or converted to liquid or gaseous fuels such as ethanol, methanol, methane, and hydrogen.
Term
British Thermal Unit (Btu)
Definition
The amount of heat required to raise the temperature of one pound of water one degree Fahrenheit; equal to 252 calories.
Term
Building Heat-Loss Factor
Definition
A measure of the heating requirements of a building expressed in Btu per degree-day.
Term
Building Orientation
Definition
The relationship of a building to true south, as specified by the direction of its longest axis.
Term
Building Overall Energy Loss Coefficient-Area Product
Definition
The factor, when multiplied by the monthly degree-days, that yields the monthly space heating load.
Term
Building Overall Heat Loss Rate
Definition
The overall rate of heat loss from a building by means of transmission plus infiltration, expressed in Btu per hour, per degree temperature difference between the inside and outside.
Term
Capacity
Definition
The load that a power generation unit or other electrical apparatus or heating unit is rated by the manufacture to be able to meet or supply.
Term
Carbon Footprint
Definition
a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc.

The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.
Term
Carbon Offset
Definition
can be used to compensate for the emissions produced by funding an equivalent carbon dioxide saving somewhere else.
