Review • Volt (E) = watt(P) divided by amp(I) § (E = P / 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 )

Kilowatt-hour • • • Basic electric power unit = watt One kilowatt (k. W)= Kilowatt-hour • • • Basic electric power unit = watt One kilowatt (k. W)= 1, 000 watts Meter records consumption period in kilowatts used = kilowatt-hours (k. Wh) (k. W) X (time, in hours) = k. Wh People use & purchase k. Whs (k. Wh X $/k. Wh = $$$ owed electric utility)

Kilowatt-hour (k. Wh) costs Example – An appliance name plate states “ 1, 400 Kilowatt-hour (k. Wh) costs Example – An appliance name plate states “ 1, 400 watts” (e. g. electric space heater): • 1, 400 watts ÷ 1, 000 watts (1 k. W) = 1. 4 k. W • (1. 4 k. W) X 2 hours per morning = 2. 8 k. W-hours • 2. 8 k. Wh X $0. 11 (price of electricity per k. Wh)=$

National electric use National annual average k. Wh use • 11, 040 k. Wh National electric use National annual average k. Wh use • 11, 040 k. Wh per year (2008) National daily average k. Wh use • 30. 2 k. Wh per day (US DOE EIA)

Baseload usage • • • Minimum amount of electric power delivered, or required, over 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
