I remember the new Energy Star usage ratings the US announced a few years
ago. Some people were getting randy about the huge losses in a freezer and
how we were stupid for not throwing out all our old appliances. Turns out
the $10 dollars per year, wasted, would never be paid for, in most of our
lifetimes, by throwing out my 30 year old freezer with no insulation in the
lid. OTOH Canada has had Energy Star usage tags and programmes for more than
30 years now.

All too often, 30 yearold fridges consume more like $6-$10 per month
more than new ones.

How about when the heating is other than resistive electric heat or
unneeded year-round, and therefore CFLs are more economical than
incandescents year-round?

Simply install two lighting systems, and use the appropriate switches in
summer or winter. Even better, automate the system so that the same
switches will power the correct set of fixtures based on the outside
temperature. (That makes it on topic for an automation news group.)
