Maybe to those folk who write Congressional impact
statements... but to the rest of us a therm is 100,000 BTU

"Therm -  One therm equals 100,000 Btu. " [a]

[a] http://www.eia.doe.gov/ask/ng_faqs.asp#ng_conversions

(and for the purposes of discussion, a therm can be
taken as being equal to a "ccf", aka a hundred cubic
feet of natural gas).

(what's a typo among friends?)

Exactly.  My conversion factors are worth what you paid for them, perhaps less.
Check, check, check.

Even though the post I was responding to was about the efficiency of
converting electricity to heat, I think it's a valuable reminder that
there are also costs involved with production and transportation of
energy, but it in an "apples to apples" comparison, we would also have
to consider those costs for natural gas, propane, fuel oil and wood,
not just electricity.

You posted some good information which I agree with the exception the
issue Danny Burstein already pointed out.

True from a "point of use" perspective, from a "point of production"
perspective there are transmission losses which aren't included in the
100% electrical to (useable) heat conversion figure, and from a
"economical comparison perspective" all cost of goods or services sold
are reflected in the point of sale price, but from a "ecological
comparison perspective" not all costs of goods or services sold are
rolled into the point of sale price and like it or not, we don't know
what the final cost will be and although we're all going to have pick
those up.

I think you are talking about economical, not efficent.
Think $/BTU.  Then electricity is not so attractive.
