  • Energy Education Program

    1. 1. Energy Conservation in the Real World ACCESS, Inc. Energy Education Program
    2. 2. Handouts Pre-Assessment Appliance Cost Worksheet Post-Assessment Evaluation
    3. 3. Overview <ul><li>Energy generation in the U.S. and Oregon </li></ul><ul><li>Energy demand and uses </li></ul><ul><li>How homes waste energy </li></ul><ul><li>Governments’ response </li></ul><ul><li>Conservation at the household level </li></ul><ul><li>Low-cost weatherization, and further savings </li></ul><ul><li>The conservation kit </li></ul><ul><li>Post-assessment and home visit </li></ul>
    4. 4. Energy in the U.S.A. <ul><li>Coal - biggest source </li></ul><ul><li>1,992 billion kWh </li></ul><ul><li>Cheap & dirty </li></ul><ul><li>Acid rain </li></ul><ul><li>Smog </li></ul><ul><li>Mercury </li></ul><ul><li>H 2 0 contamination </li></ul><ul><li>Nuclear </li></ul><ul><li>789 billion kWh </li></ul><ul><li>Sustainable </li></ul><ul><li>Waste storage issues </li></ul><ul><li>Potentially dangerous </li></ul><ul><li>Susceptibility to </li></ul><ul><li>sabotage </li></ul><ul><li>Hydroelectric </li></ul><ul><li>285 billion kWh </li></ul><ul><li>Inexpensive </li></ul><ul><li>WA, OR, & CA are </li></ul><ul><li>largest producers </li></ul><ul><li>Fish & wildlife </li></ul><ul><li>issues </li></ul><ul><li>Renewables </li></ul><ul><li>98 billion kWh </li></ul><ul><li>Wind </li></ul><ul><li>Solar </li></ul><ul><li>Geothermal </li></ul><ul><li>Biomass </li></ul>
    5. 5. Green at 97,000 Feet... <ul><li>“ Pathfinder” and “Helios” solar aircraft </li></ul><ul><li>developed by NASA to replace satellites </li></ul><ul><li>Set UAV altitude record in 2001 </li></ul><ul><li>Capable of sustained flights of </li></ul><ul><li>a week or more </li></ul>
    6. 6. Energy in Oregon <ul><li>Hydroelectric dams make </li></ul><ul><li>up the majority of the </li></ul><ul><li>state’s electricity supply </li></ul><ul><li>One coal-fired plant; generates about 7% of supply </li></ul><ul><li>Major transmission lines allow for energy </li></ul><ul><li>transfer to/from WA & CA </li></ul><ul><li>Remainder supplied by natural gas </li></ul>
    7. 7. How Homes Use Energy Baseload : home’s minimum continuous power demand <ul><li>Four heaviest users: </li></ul><ul><li>Heating/cooling </li></ul><ul><li>Water heating </li></ul><ul><li>Fridge/Freezer </li></ul><ul><li>Incandescent lighting </li></ul>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%
    8. 8. Vampire Power Loads <ul><li>Any non-baseload device </li></ul><ul><li>using continuous power </li></ul><ul><li>Vampire devices can often </li></ul><ul><li>cancel out efficiency of </li></ul><ul><li>baseload upgrades </li></ul><ul><li>About $60 per house </li></ul><ul><li>annually, or $9 billion </li></ul><ul><li>nationwide </li></ul><ul><li>“ Vampire” or “parasitic” </li></ul><ul><li>loads account for over 4% </li></ul><ul><li>of average home’s energy </li></ul><ul><li>costs </li></ul>
    9. 9. Your Power Bill 315 Thermal Bndry Rd Kilo, WA Anita Weatherization 123 Thermal Boundary Rd Kilo, WA 89402 96255873-110 123456
    10. 10. 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
    11. 11. 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?
    12. 12. How Homes Waste Energy Five major areas <ul><li>Air infiltration </li></ul><ul><li>Doors/windows </li></ul><ul><li>Floors </li></ul><ul><li>Walls </li></ul><ul><li>Ceilings </li></ul>
