Today's talk ACT I Energy Efficiency (EE) ACT II Solar Energy (SE) ACT III Electric Vehicles (EV)
What do you do with an idea? * ACT I Energy Efficiency (EE) * from the book wripen by Kobi Yamada IllustraMon: Mae Besom
Home Electricity Bill Do you know what you spend per month? 4
Home Electricity Bill Do you know what you spend per month? Do you know how much electricity you use per month (kwh)? 5
Average Alberta Household 7,200 kwh / year
Average Alberta Household 7,200 kwh / year 600 kwh / month
How much electricity was our house 1014 kwh / month using? [chart showing our 2012-2014 annual power consumpmon data 12 172 kwh/yr] [1 014 kwh / month] [254 kwh / person / month [8 kwh / person / day] 9
Why are we using so much electricity? Where is it going?

Where was all our electricity going? Clothes Cooking Dishwasher Fridge & Freezer Furnace Fan LighMng 340 kwh/mth. Really!!! 16
340 kwh/month for lights (38%) Incandescent: 8 X 100W = 800W 18
Old Beer Fridge 75 kwh/month (7%) 19
The "Pig & Hog" Washer 10 kwh/mo Dryer 140 kwh/mo 20
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
Can we reduce w/o impacmng our lifestyle?
Incandescent: 8 X 100W = 800W vs. LED: 8 X 9W = 72W 23

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

What's the solar payback? * ACT III Electric Vehicle (EV) * esmmated IllustraMon: Mae Besom
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 $0.120351/kWh = $1,456/yr 21,000 km cost of Nissan Rogue $2,835 2,835 litres @ $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
Solar (EsMmated) Payback OpMon 1 Energy Efficiency (EE) Only reduce from 12,100 to 5,200 kwh/yr cost 5,200 kwh x $0.120351/kWh = $626 save/cash flow $1,456 - $626 = $830/yr
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
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 (3,484 + 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
Solar (EsMmated) Payback OpMon 2 EE + SE (no incenmves) 9 KW solar system @ $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
