This is in Central Oregon where electricity is cheap (for now) and dino fuel
is expensive. Diesel is past $4.00 and propane isn't far behind.
Nice thing about electricity is the lack of required venting.

Electricity $0.055 / kWh? Is that the actual cost per kWh, or are you
only looking at the generation charge and missing the distribution
charge? Most of the US is paying $0.100 or more per delivered kWh.
