For years the fuel of choice in a rural setting was propane. It was
70-90 cents/gal. Now it is 2.10/gal and btu for btu yielded you can
heat with low-tech electric resistance heat for less money.

1 Million BTU Electricity = $24.90 (TN)

$24.90 would be about 400 KWH here, and that
could produce more than 1.2 million BTU.

1 Million BTU Propane (80% Furnace)=$28.46

Out of curiosity I checked the price for propane
17 pound bottle refills at Lowes, and it was $18, that
is a lot more than $2.10 a gallon, isn't it.

But maybe in bulk it is cheaper.

The temperature here fell through -10 C
during daylight here today, and that could mean
life threatening temperatures without backup heat,
regardless of what the fuel is, furnaces and anything
else can fail even if there is plenty of fuel.

The high tech furnaces are a threat, even
if they are supposed to be more efficient, fuel cost
is not as important as avoiding unsafe temperatures.
