Established in1997
Treaty Based
70 Tribes andFirst Nations
Almost Every dot Is a “micro-grid"
The Yukon River Inter-Tribal Watershed Council
#1 Heat Energy – Fairbanks has 14,000 annual Heating Degree Days
Any guesses as to how many heating degree days in Toronto?
Major Rural Energy Challenges
#2 Electricity ◦ Avg Price in Anchorage: .09/kW◦ Avg Price in Pedro Bay: .91/kWh
#3 Transportation – Subsistence?
#4 Human Nature, Perverse Incentive

How much is this timer worth
Analyze options Waste Oil – Heat Efficient Lighting Timers/Occupancy Sensors
<- Biggest Energy Draw?
New Construction Vs. Old construction Nenana School District Dormitory
Properly Evaluate your home energy use – WHERE does it go!?
Windows, Air Leaks, no insulation
Insulate and Seal
What’s the difference?
Heat Lamp Flood Lamp LED
Lighting
What’s the difference?

…If a tree falls in the forest…
Solar Thermal, Solar PV, Heating upgrade Nenana Youth Rec Center
Projects!
# of Panels: 20
Panel Type: Trinna 220watt
Total Array Size: 4.4 kW
Energy Produced: 5,100 kWh/yr
Cost of Electricity in Nenana: $.20/kWh
Energy Value per year: $1020
Cost of equipment and supplies: $15,000
Simple Payback: $15k/$1020 = 14.7yrs
Solar PV Energy Production:
# of bulbs: 132
Tube bulb Type: 15 watt LED tubes
Total Time for Change-out: 12 person-hours
Energy SAVED: 12,000 kWh/yr
Cost of Electricity in AKP: $.35/kWh
Energy Value per year: $4200
Cost of equipment and supplies: $6,600
Simple Payback: $6600/$4200 = 1.6yrs
Lifetime Energy Saved (bulbs 50k hrs): $40k-50k
Lighting Change-out
Free Heat during the summer
How much do we pay to heat water during the summer?
Solar Thermal
Village Scale Wind - Issues?
SkyStream 3.7 Wind Turbines
Class 6 Wind
6.7 m/s Avg windspeed
Hooper Bay Small Wind
600 kWh/month
Energy in Hooper Bay $.514/kWh
Turbine Cost $20k
Yearly Energy Value 600kWh X 12 mo = 7,200 kWh
7,200 kWh x $.514/kWh = $3,700
PAYBACK: $20,000 / $3,700 = 5.4 yrs
Hooper Bay Small Wind
How Hard is it to instal?
Every 1$ spent on Energy Efficiency is worth $5 spent on Renewable Energy Projects
Somebody should do something about that…
