Energy Education Program Energy Education Program Presentation Transcript

  • Energy Conservation in the Real World ACCESS, Inc. Energy Education Program
  • Handouts Pre-Assessment Appliance Cost Worksheet Post-Assessment Evaluation
  • Overview
    • Energy generation in the U.S. and Oregon
    • Energy demand and uses
    • How homes waste energy
    • Governments’ response
    • Conservation at the household level
    • Low-cost weatherization, and further savings
    • The conservation kit
    • Post-assessment and home visit
  • Energy in the U.S.A.
    • Coal - biggest source
    • 1,992 billion kWh
    • Cheap & dirty
    • Acid rain
    • Smog
    • Mercury
    • H 2 0 contamination
    • Nuclear
    • 789 billion kWh
    • Sustainable
    • Waste storage issues
    • Potentially dangerous
    • Susceptibility to
    • sabotage
    • Hydroelectric
    • 285 billion kWh
    • Inexpensive
    • WA, OR, & CA are
    • largest producers
    • Fish & wildlife
    • issues
    • Renewables
    • 98 billion kWh
    • Wind
    • Solar
    • Geothermal
    • Biomass
  • Green at 97,000 Feet...
    • “ Pathfinder” and “Helios” solar aircraft
    • developed by NASA to replace satellites
    • Set UAV altitude record in 2001
    • Capable of sustained flights of
    • a week or more
  • Energy in Oregon
    • Hydroelectric dams make
    • up the majority of the
    • state’s electricity supply
    • One coal-fired plant; generates about 7% of supply
    • Major transmission lines allow for energy
    • transfer to/from WA & CA
    • Remainder supplied by natural gas
  • How Homes Use Energy Baseload : home’s minimum continuous power demand
    • Four heaviest users:
    • Heating/cooling
    • Water heating
    • Fridge/Freezer
    • Incandescent lighting
    More efficient baseload appliances, yet Americans consume more energy now than ever... Why?? Source: Pacific Power & Light Heating/Cooling 36% Water Heater 25% Refrigerator/ Freezer(s) 15% Incandescent Lighting 9% (fluorescent lighting only uses about 2%) Electric Range/Oven 5% Clothes Dryer 3.5% T.V. 2.5% Dishwasher 1.5% Clothes Washer <1% Computer <1% Other Appliances 2%
  • Vampire Power Loads
    • Any non-baseload device
    • using continuous power
    • Vampire devices can often
    • cancel out efficiency of
    • baseload upgrades
    • About $60 per house
    • annually, or $9 billion
    • nationwide
    • “ Vampire” or “parasitic”
    • loads account for over 4%
    • of average home’s energy
    • costs
  • Your Power Bill 315 Thermal Bndry Rd Kilo, WA Anita Weatherization 123 Thermal Boundary Rd Kilo, WA 89402 96255873-110 123456
  • What is a Kilowatt-hour? Approximate cost in Oregon = $.085 (8.5 ¢) per kWh Divide month’s charges by month’s usage… How do we calculate cost per kWh? Examples: 100W bulb left on for 10 hours = 1 kWh 2000W hairdryer for 1/2 hour = 1 kWh 1,000 watts consumed over one hour = 1 kWh “ Kilo” means “thousand,” so… Kilowatt-hour (kWh) is a RATE Kilowatt (KW) is an AMOUNT
  • Calculating Appliance Cost Determine wattage and time period you want to estimate (day, month, year, etc) = $45.90 per month! 1500 x 12 x 30 x .085 = 45.9 1000 Watts x Hours Used x Days x .085 = cost 1000 For example, How much will using my 1500W space heater 12 hours a day add to my monthly bill?
  • How Homes Waste Energy Five major areas
    • Air infiltration
    • Doors/windows
    • Floors
    • Walls
    • Ceilings
  • U.S. Government Actions
    • Energy Star Program
    • Joint promotion between EPA and DOE since 1992
    • Only products meeting strict federal guidelines earn label, helps consumers choose wisely
    • Weatherization Assistance Program
    • Nearly 6 million households helped since 1976
    • DOE funds work through 900+ service providers
    • (usually agencies like ACCESS)
    • Nationwide, average annual savings of $358/house
  • Around the World...
    • GERMANY - Renewable Energy Sources Act
    • Requires power companies to buy all energy
    • generated by solar systems for 20 years
    • Private homeowners, farmers, etc. install systems
    • and earn reliable return on investment
    • Germany leads world in solar electric production
    • BAN ON INCANDESCENTS
    • Ireland - 2009
    • Philippines - 2010
    • Australia - 2012
    • USA (Clean Energy Act) - 2014
    • ISRAEL - Solar water heating
    • Law requires all new construction to include rooftop
    • solar water heaters
    • 75% of Israeli households use sun to help heat
    • water
  • Thermal Dynamics Heat moves in three ways... RADIATION CONVECTION CONDUCTION
  • Thermal Dynamics INSULATOR: Material that resists conductive heat loss Most weatherization work involves insulation and air sealing . Home efficiency demands both. INSULATION AIR SEALING
  • Thermography Failing door weatherstrip Leaking fridge door Brand new home... What’s missing here? Only $6,500!
  • Conservation at Home KEEPING WARM IN THE BEDROOM IN THE KITCHEN REST OF HOUSE
    • Balanced HVAC system - keep all grilles unobstructed
      • Set thermostat as low as comfortable - every 1º is 2% power bill savings
      • Don’t let furnace filter or fan get too dirty - HUGE efficiency drop
      • Keep furniture away from baseboards
      • Make sure dryer is vented OUTSIDE - and hose unobstructed
      • Buy or make Styrofoam fireplace plug
      • Fridge - clean coils once a year, keep away from heat sources
      • DO NOT use the oven just for heat - expensive, CO danger with gas ovens
      • Try to cook less in summer (salads, etc.)
      • Cook individual meals in microwave/toaster oven, save $50/year
      • Electric blanket (200 watts) = 5x cheaper than space heater
      • Curtains/drapes resist heat loss through windows
      • Keep thermostat low - 55-60 ºF
  • Conservation at Home WATER WASTE
    • Use shutoff nozzle for watering
      • Open garden hose uses five times more water per min than shower
    HOSES
    • Most common cause of leaks is broken washers & gaskets
      • Steady one-second drip can waste over 2,500 gallons per year
    SINKS
    • Use bottles, bags, etc. to displace water volume in older, inefficient toilet tanks
      • Some cleaning chemicals damage rubber flapper
      • Try dye/food coloring in tank to check for silent leaks
    TOILETS
      • Showerhead older than 1992? Replace
      • Ten-minute shower @ 120 ºF every other day = 4,562 gal/year = $29.58
      • Baths use twice as much hot water as average shower
      • Brevity. Every extra minute of average daily usage adds 913 gallons of hot water per year
      • Average Medford home uses 166k gal/year
    SHOWERS
  • A Look at Your Water Heater
    • Electric: shut off WH breaker,
    • unscrew upper & lower panels
    • and turn temp needle with screw
    • driver
    • Gas: adjust temp with dial at
    • bottom
    • With age, dip tubes can corrode,
    • mix cold & hot water, hamper
    • efficiency
