  3. Review • Volt (E) = watt(P) divided by amp(I) • (E = P / I) • Amp (ampere) (I) = watt(P) divided by volt(E) • (I = P / E ) • Watt (P) = volt (E) multiplied by amp(I) • (P = E * I ) 2010 Energy OutWest Reno, Nevada

  4. Kilowatt-hour • Basic electric power unit = watt • One kilowatt (kW)= 1,000 watts • Meter records consumption period in kilowatts used = kilowatt-hours (kWh) • (kW) X (time, in hours) = kWh • People use & purchase kWhs • (kWh X $/kWh = $$$ owed electric utility) 2010 Energy OutWest Reno, Nevada

  5. Kilowatt-hour (kWh) costs Example – An appliance name plate states “1,400 watts” (e.g. electric space heater): • 1,400 watts ÷ 1,000 watts (1 kW) = 1.4 kW • (1.4 kW) X 2 hours per morning = 2.8 kW-hours • 2.8 kWh X $0.11 (price of electricity per kWh)=$ 2010 Energy OutWest Reno, Nevada

  6. National electric use National annual average kWh use • 11,040 kWh per year (2008) National daily average kWh use • 30.2 kWh per day (US DOE EIA) 2010 Energy OutWest Reno, Nevada

  7. Baseload usage Minimum amount of electric power delivered, or required, over given period of time at somewhat steady rate (~ 10% fluctuation) Electricity used to operate house, minus heating & cooling (seasonal peaks sitting on top of baseload) Controlled by efficiency, behavior & education 2010 Energy OutWest Reno, Nevada

  8. Baseload daily average 2010 Energy OutWest Reno, Nevada

  9. 2010 Energy OutWest Reno, Nevada

  10. Determining electricity end use Nameplates & measuring Monitoring, data logging, load profiling Whole house, individual devices The house meter as a tool Watching & record keeping 2010 Energy OutWest Reno, Nevada

  11. Nameplate information • Lamp • 30w 2010 Energy OutWest Reno, Nevada

  12. Nameplate information 6.5 amps “about” (because it’s a motor) 6.5 X 120V = 780w 780/1000 = .78kW X 2 hours on = 1.6 kWh X $0.11 / kWh = $0.18 cost 2010 Energy OutWest Reno, Nevada 12

  13. Nameplate information 25 watts 25/1000=.025 kW 5 hours on =0.125 kWh X $0.11 / kWh $0.014 cost 2010 Energy OutWest Reno, Nevada

  14. Nameplate information 4500 watts 4500/1000 = 4.5 kW 4 hours on = 18 kWh X $0.11 / kWh $1.98 cost 2010 Energy OutWest Reno, Nevada

  15. Monitoring tools Some tools Monitor Meter Monitor 2010 Energy OutWest Reno, Nevada Recording

  16. Residential house meters • “Turtle” automatic meter reading meters • Could be configured “Smart” 2010 Energy OutWest Reno, Nevada

  17. Residential house meters • Three types typical residential meters • Meter measures usage, kWhs • Difference between prior & present readings = kWh used & purchased 2010 Energy OutWest Reno, Nevada
