Bill,
I had sent this offline to Noel as I didn’t think it was that
jewelry related, however this will answer your question I think.
Sorry I had to wait till I got home to do a bit of digging.
Here is 2 tables taken from a Government of Canada website

First factor in the efficiency of each type (Table 1) if we assume
they are older conventional units
Electric baseboard = 100%
Oil Furnace = 60%
Propane furnace = 60%
So to deliver the same heat say you need 1,000,000 btu of electric
or 1,667,000 of oil or propane to deliver the same heat.
Next Determine the Price of Energy Sources in Your Area
Call your local fuel and electricity suppliers to find out the cost
of energy sources in your area. This should be the total cost
delivered to your home, and it should include any basic cost that
some suppliers might charge, along with necessary rentals, such as a
propane tank. Be sure to get the prices for the energy sources in
the same units as shown in Table 3. Write the costs in the spaces
provided. Table 3. Energy = Content and Local Price of Various Energy
Sources Energy Source Energy Content Local Unit Price So take you
local costs and then figure the price to make 1 million BTU of
electricity or 1,667,000 of oil or propane and you will have an idea
of which is cheaper or more expensive.
Electricity 3 413 Btu/kWh $0._____ /kWh
Oil 140 000 Btu/gal (US) $0._____ /litre
Natural Gas 1 007 Btu/ft " $0._____m "
Propane 92 700 Btu/gal (US) $0._____litre
With that you will really know what costs more or less in your area.
Now the catch of course is the house may not be insulated which will
drive up heating costs… or may just need calking and
weather-stripping. Another possibility is an outside BBQ connection
that is leaking propane and no one has noticed which would drive the
usage trough the roof.
Another overlooked point of usage is the pilot light, often people
leave it burning year around. If your area is so temperate that you
really don’t need any heating 6 months of the year and are willing
to tolerate a few cold mornings, then turning the gas off to the
furnace can save a lot.
Mind you if you combine the furnace, clothes dryer and stove being
furnished from the same tank yes dollar for dollar your costs will
be higher than a house that heats with oil and only uses oil for
heating.
The trick is take all energy costs for a given home (Oil, propane
and electricity for a year into account). If you want to compare
between 2 houses.
Which costs more to heat
My house with an annual electric bill of $4000.00 or my mother in law
with a $3600.00 propane bill and $800.00 electricity bill?
Or
A guy down the street who pays 2800.00 for oil (Heat only) plus
2000.00 for electricity (to heat water, dry clothes and general base
load)?
See why the numbers are so slippery?

PS you have to understand we have at least 1 week of -40 during the
winter and several weeks of really cold windy weather, so our costs
are a lot higher than say someone in Virginia,
