  • Session ObjectivesLearn how to separate electric baseload from whole house electric useExplore how occupants, equipment, and use patterns affect electricity consumptionEvaluate options and actions to reduce use

  • Todays TopicsThe equipment we will talk about today:ElectronicsLightingRefrigerationWater HeatingAnd a few other thingsWhat they useHow they workWhat can be done in terms of measures and behaviors

  • Weatherization Core Competencies

  • Baseload + Seasonal = Total Household Electric UseBaseload: Electricity that power thingslights and appliances--used year roundSeasonal use: Electricity used to provide heating, cooling, often dehumidification

    The goal is to understand how a particular household uses electricity, identify the possibilities for reducing that use and dialogue with the occupant for the best possible outcomes.

  • Houses dont use energy. People do.

  • Reasons to Address BaseloadSometimes, reducing electric baseload can guarantee better savings than measures geared toward reducing the cost of heating and/or cooling: Savings Follows Use.Plug loads are increasing.Electric energy waste (energized equipment not in active use) is increasing.

  • Electricity originates inside clouds. There it forms lightning, which is attracted to the earth by golfers. After entering the ground, the electricity hardens into coal, which, when dug up by power companies and burned in big ovens called generators, turns back into electricity, which is sent in the form of volts (also known as watts or rpm for short) through special wires with birds sitting on them to consumers homes, where it is transformed by TV sets into commercials for beer, which passes through the consumer and back into the ground, thus completing what is known as a circuit.Dave Barry, Funny Times, 2002

  • Electricity: Energy & PowerEnergy From meter to utility billpower over time

    Watt hour - Wh kiloWatt hour - kWh (1,000 Wh)

    Power Nameplate potential instantaneous demandWatt - WkiloWatt (1,000 W) kWWatt - is one joule per second or the power supplied when a current of one ampere is driven by a potential difference of one volt

  • Establish Baseload UseObtain (a printout of) the customers electricity use for at least one year prior to the site visit.Separate the baseload use from the total use by:adding together the three lowest months (not weird numbers) dividing the sum by 3 to get an average baseload months use multiplying that number by 12 months

    This can easily be done visually from a bar chart. There are lots of ways to do this. They all work.

  • Assess the Opportunity for Energy SavingsDetermine if the customers use is in the low, mid range, or high range using their consumption history or data on their utility bills.Focus your efforts in the home based on your determination.Since savings follows use, you will likely find more opportunities to save energy where the use is high.If any category of use is low, then save time and focus where the use is medium or high

  • Savings Follows Use / WasteTotal electricity use relates directly to potential electricity savings

  • Reasons for High BaseloadTime on 24/7 adds up quicklyHigh demand / power (kW)Poor control strategiesNot known to be operatingFaulty equipmentIntermittent useHidden loadsLots of people in the householdPPL Managing CAP Credits Pilot Program, 2006

    2007 Ecos Consulting, Final Field Research ReportRoughly 1 to 2% of U.S. electricity could be saved by improving power supply efficiency

    $2.1 to 4.2 billion saved by consumers on their electricity billsPrevent release of 40 to 80 million tons of CO2 into the atmosphereEquivalent of taking 2.3 to 4.6 million cars off the roadEquivalent of building roughly 4.5 to 9 average sized power plants

  • Sample Annual kWh of TVs by Mode

    Standby power is similar regardless of TV type or size.Newer TVs use a lot more energy than older ones.Larger and newer technologies (plasma & rear projection) tend to be used more and are frequently part of a larger entertainment set up.Source: Ecos Consulting, Final Field Research Report, 2007

  • Managing Computer Power UseTeach everyone that it makes sense to Turn off monitor if not using for > 5-20 min. and both CPU and monitor if not using for > 30-60 min.Use power strips for positive off and control of peripheralsLearn about and teach others about how to Activate Power Management FunctionsMaximize sleep features in the operating system

  • Battery Charging StrategiesChargers can draw 5 to 20 times more power than they can store so...Unplug chargers once battery is chargedUse timer to control charge cycleChoose equipment based on charging performanceBuy efficient chargersUse rechargeable batteriesUse power strips to simplify disconnecting chargers
