EPA Recommended Sustainability Threshold
Lower 48 Average
Water and sewer bills in rural Alaska range from $80 to $250 per month, and average 3-8% of median household income; this confluence of factors is a direct threat to the sustainability of public sanitation across rural Alaska.

Creates local jobs for woodcutters and operators 4

10. Excess Wind-to-Heat – Mekoryuk, Alaska
ANTHC Rural Energy Initiative
Excess Wind-to-Heat – Mekoryuk, Alaska
Utilize dispatchable wind electricity to provide heat to the sanitation system.
Cost of $0.05 per kWh equivalent to fuel oil at $1.46 per gallon
Projected annual savings of almost $40,000 4

11. Geothermal Ground Source Heat Pump – Metlakatla, Alaska
ANTHC Rural Energy Initiative
Geothermal Ground Source Heat Pump – Metlakatla, Alaska
Vertical Well GSHP system will replace oil fired heating at the Lepquinum Pool & Wellness Center
Heat Pump will cover 94% of yearly heating load
Building heating system upgrades required
2 existing oil-fired boilers will remain as backup and for peak heating
Energy Savings = $202,000 per year
