| energy |
The result of consuming power over a period of time. In electricity, measured in watthours: 1000 watthours = 1 kilowatt hour, or the equivalent of a 100 watt bulb running for 10 hours. Most electricity rates/prices for residential service are quoted in kilowatt-hours. In gas, measured in volumes of gas (cubic feet) or a proxy for volumes (therms, qv).
