Gas vs Electric Heating Cost in Oregon
In Oregon, a 2,000 sq ft house with average insulation costs an estimated $1,352.40 a year to heat with a 92% gas furnace, $3,617.12 with electric resistance heat and $1,291.83 with a heat pump. Between gas and a heat pump, Oregon is a close call: the cheaper one, a heat pump, wins by $60.57 a year at average prices.

At 16.0¢/kWh, Oregon has the 29th-highest electricity rate among the 50 states and DC. Residential gas in Oregon is $1.61/therm, 9% above the US average of $1.48/therm. A winter of 4,600 heating degree-days means the 2,000 sq ft example in Oregon needs about 77.3 MMBtu of heat a year.

Worked example
Worked example: 2,000 sq ft in Oregon
A 2,000 sq ft house with average insulation in Oregon needs about 77.3 MMBtu of heat a year (4,600 heating degree-days). At $1.61/therm in a 92% furnace, gas delivers that heat at $17.50 per MMBtu; resistance heat at 16.0¢/kWh costs $46.81, and a heat pump at seasonal COP 2.8 (zone 4) costs $16.72. The year comes to $1,352.40 on gas, $3,617.12 on resistance heat and $1,291.83 on a heat pump. That is a near-tie: a heat pump comes out ahead by $60.57 a year, and a price change of about 10% on either side could reverse it.
Load = sq ft × 0.35 × heating degree-days × 24 ÷ 1,000,000. Gas $/MMBtu = $/therm ÷ 0.1 ÷ 0.92. Resistance $/MMBtu = $/kWh × 293.07. Heat pump = resistance ÷ COP.
Questions
FAQ
Which is cheaper in Oregon, gas or electric heat?
Electric resistance heat is the most expensive of the three in Oregon: $3,617.12 a year for the 2,000 sq ft example, $2,264.72 more than gas. Between gas ($1,352.40) and a heat pump ($1,291.83), the two are within about 10% per unit of heat ($16.72 vs $17.50 per MMBtu), so your own rates decide. These are estimates at 16.0¢/kWh and $1.61/therm; your bill's prices can change the answer.
How much gas does a furnace use in Oregon?
About 840 therms a year for a 2,000 sq ft house with average insulation and a 92% furnace, at Oregon's 4,600 heating degree-days. That averages 70 therms a month over 12 months, but almost all of it is burned in the heating months. At $1.61/therm, the year costs an estimated $1,352.40.
Electric furnace vs gas furnace cost in Oregon?
An electric furnace is resistance heat: every kWh gives 3,412 BTU. At 16.0¢/kWh, that heat costs $46.81 per MMBtu in Oregon, against $17.50 from a 92% gas furnace at $1.61/therm, 2.7 times as much. For the 2,000 sq ft example that's $3,617.12 a year against $1,352.40.
