An "All Electric" house can be quite cost effective. You have to have
electric service anyway and when you have, say, gas heat you pay the top
seasonal rates for both gas and electric. With all electric you save
(directly and indirectly) the cost of bringing one more utility to your
property including stuff like reading the meters.

If your thinking geothermal heat pump heating, then you might be correct.
If you're talking about resistive heating in cold weather and air-to-air
heat pump in mild weather, then you don't understand electric rates in
the northeast US.
