I was chastised the other day by a friend of a friend for using my oven. I
said that I liked to use it a lot in the winter for baking and such because
it helped warm up the house and that meant I could often keep the heat off
when it was on. She told me that it is very costly to run an electric oven
and that I shouldn't use it. Told me if I didn't believe her to go look at
my meter next time it was on. I can't see that would help me as I am not in
the habit of looking at my meter so don't know what it does to begin with.

Anyway... Is there any truth to this? This person has told me a lot of other
things that were wrong.
