How to use the chart

Find the chart of the electric heat you're considering i.e. air-to-air heat pump; geothermal (ground source) heat pump or electric resistance heat.

Find the kWh price for electricity and compare it to prices for propane, natural gas, and oil on the same line.

For example, geothermal systems, with electricity at 6.05 cents/kWh is equal to propane (in a 90% efficient furnace) at 49 cents/gallon. If propane costs more, it's a more expensive form of heat.

	Electricity Water/Air HP (COP 3) (cents/kWh)	Fuel Oil Regular (60% eff.) ($/gal.)	Propane Regular (90% eff.) ($/gal.)	Natural Gas Regular (80% eff.) ($/therm)	Natural Gas Super Eff. (90% eff.) ($/therm)
Geothermal & Ground Source Heat Pumps 300% Efficient	6.05	0.49	0.49	.047	0.53
Air to Air Heat Pump 200% Efficient	6.05	0.73	0.73	0.71	0.80
Electric Resistance 100% Efficient	6.05	1.47	1.46	1.42	1.60

Audits

Members with existing homes can select the energy audit level that fits their needs. The assessment findings and recommendations will provide weatherization and energy saving techniques that are eligible for our weatherization program. Please contact our Energy Services Specialist at 1-800-234-1960 to schedule an audit. An audit must be conducted prior to any work being performed to be eligible for the weatherization rebate program.

Level I:

• On-site visual assessment based on member needs and prospective weatherization project which can include inspections of insulation, windows, and doors.
• The charge for Level I audits is $45 plus applicable tax. This fee will be reimbursed if you submit a weatherization rebate application for any of the energy saving measures as recommended in the audit. 

Level II:

• On-site visual assessment based on member needs and prospective weatherization project which can include inspections of insulation, windows, and doors.
• Incudes the option of a blower test and Infrared camera imaging to help detect voids, missing/damaged insulation, and home efficiency.
• The charge for Level II audits is $175 plus applicable tax and will be provided by a third-party contractor. $75 plus tax will be reimbursed if you submit a weatherization rebate application for any of the energy saving measures as recommended in the audit. 
• For the most beneficial results, this audit is available November-March.
