2 Today's talk ACT I Energy Efficiency (EE) ACT II Solar Energy (SE) ACT III Electric Vehicles (EV)

3 What do you do with an idea? * ACT I Energy Efficiency (EE) * from the book wripen by Kobi Yamada IllustraMon: Mae Besom

4 Home Electricity Bill Do you know what you spend per month? 4

5 Home Electricity Bill Do you know what you spend per month? Do you know how much electricity you use per month (kwh)? 5

6 Average Alberta Household 7,200 kwh / year

7 Average Alberta Household 7,200 kwh / year 600 kwh / month

9 How much electricity was our house 1014 kwh / month using? [chart showing our annual power consumpmon data kwh/yr] [1 014 kwh / month] [254 kwh / person / month [8 kwh / person / day] 9

10 Why are we using so much electricity? Where is it going?

11 DIY Home Power Audit Plug meter measures energy

16 Where was all our electricity going? Clothes Cooking Dishwasher Fridge & Freezer Furnace Fan LighMng 340 kwh/mth. Really!!! 16

17

18 340 kwh/month for lights (38%) Incandescent: 8 X 100W = 800W 18

19 Old Beer Fridge 75 kwh/month (7%) 19

20 The "Pig & Hog" Washer 10 kwh/mo Dryer 140 kwh/mo 20

21 Other examples of monthly energy usage Boiling water 6.4 kwh Microwave 4.0 kwh Vacuum 4.6 kwh Hairdryer 900 Wh 3 clocks running for 1 year is 60.4 kwh enough to power our house for 4 days Toaster & Coffee maker 9.7 kwh Deep freezer 30 kwh Clothes Washer 10 kwh Kitchen fridge 32.2 kwh Bathroom fans (2) 1.8 kwh Ceiling fan (24hrs/day) is 7.3 kwh 21

22 Can we reduce w/o impacmng our lifestyle?

23 Incandescent: 8 X 100W = 800W vs. LED: 8 X 9W = 72W 23

24 Over 80 bulbs (5968 WaPs) were replaced with LED

35 Other ways we reduced wasted electric energy Eliminate ghost power by "turning off" using a power bar. (7% reducmon) Wash clothes in cold water; use dryer sparingly, and drying racks Use ECO setng on dishwasher & air dry dishes Keep heat in with triple pane windows Programmable thermostat: turn down to 15 C at night new LED TVs use less energy 35

36 Put them on a power bar so that "off" is really OFF... 36

50 What's the solar payback? * ACT III Electric Vehicle (EV) * esmmated IllustraMon: Mae Besom

52 Solar (EsMmated) Payback Base Case (BAU do nothing) Home & Car 12,100 kwh cost of electricity: $1,456 (energy cost 6.2c/kWh + energy delivery 5.8 c/kwh) 12,100 kwh x $ /kWh = $1,456/yr 21,000 km cost of Nissan Rogue $2,835 2,835 $1/Ltr Total Base Case Cost $4,291/year (energy only) assumpmons (details in my paper solarcafe.ca) no change in electricity rate or gas price in 5 years

53 Solar (EsMmated) Payback OpMon 1 Energy Efficiency (EE) Only reduce from 12,100 to 5,200 kwh/yr cost 5,200 kwh x $ /kWh = $626 save/cash flow $1,456 - $626 = $830/yr

54 Solar (EsMmated) Payback OpMon 2 EE + Solar Energy (SE) (9.01KW) Solar PV generates 8,709 kwh home uses 5,200 kwh/yr energy cost $0 + energy delivery charges ($203) electricity export 3,509 x 6.2 c/kwh = $218 carbon offsets (RECs) 3,509 x 1.85c/kWh = $65 save/cash flow ($1,456 - $203) + $218 +$65 = $1,536/yr

55 Solar (EsMmated) Payback OpMon 3 EE + SE + Electric Vehicle (EV) reduce from 12,100 to 8,700 kwh/yr i.e. 5,200 kwh (house) + 3,500 kwh (car) solar produces 8,700 kwh/yr so energy cost $0 however, delivery charges for home & car (3, ,500 kwh) x $0.058 = $405 (assumes car charges at night) save $2,835 gasoline (@ $1/ltr) 21,000 km/yr save/cash flow $1,456 - $405 + $2,835 = $3,886

56 Solar (EsMmated) Payback OpMon 2 EE + SE (no incenmves) 9 KW solar $3/waP = $27,000 savings/increased cash flow $1,536/yr simple solar payback $27,000/$1,536/yr = 17.6 yr OpMon 3 EE + SE (with incenmves) + EV same solar system cost $20,250 (@$2.25/waP) savings/increased cash flow $3,886/yr simple solar payback $20,250/$3,886/yr = 5.2 yr
