E

efficiency: Ability to produce a desired effect or product with a minimum of effort, expense, or waste.

electric outlets: Areas where appliances can be plugged in to receive electricity.

Electrical outlet

electricity: An electric current supplied by a public utility for lighting or heating.

energy: The capacity of a physical system doing work.

Energy Star: A voluntary partnership with equipment manufacturers across a variety of industries to reduce the power consumption and the pollution associated with the use of electricity.

F

fluorescent light: A glass tube/bulb that is coated with a fluorescent substance that gives off light when the mercury vapor inside the tube is acted upon by a current.

Fluorescent tube

G

gas: The fluid form of a substance which can expand indefinitely (not a solid or a liquid)

generator: A machine for producing electricity

Generator

H

high pressure steam: Water is heated to create steam and is then forced against the blades of a turbine at high pressure to power a generator

I

incandescent: Glowing with intense heat; shining brightly; a lamp in which the light is produced by a filament of conducting material contained in a vacuum and heated to incandescence by an electric current

Incandescent light bulb

insulate: To cover with a non-conductive material in order to prevent the passage or leakage of electricity or heat

insulation: Any material used to insulate

Worker installing insulation

K

kilowatt: A unit of electrical power equal to 1,000 watts

kilowatt-hour (kWh): A unit of electrical energy or work equal to the power supplied by one kilowatt for one hour

L

lifetime cost: The cost of an appliance over the lifetime of the appliance

light emitting diode (LED): An electronic component that gives off light when activated. LED bulbs are more efficient than incandescent or compact fluorescent bulbs.
