As soon as you start heating your house, saving energy on
incandescent lightbulbs and computers and monitors becomes rather
futile: the energy that you save on those still has to be spent on
plain heating. The big difference might be that e.g. you pay
HydroQuébec instead of GazMétro, so you generate less CO2 and pay a
bit more (until the price of methane goes up), but if your heating
is all-electric there is no difference.At this point in the year, though, it matters to me: air
conditioner is on, it's back to 30°C in Montréal. If you use air
conditioning, heating matters twice because not only it's generated
but it also takes extra energy to take it out of the house.Energy saving ratings never take this into account, afaik.
You overlooked one thing, which is that it is a lot more expensive to
heat with electricity than combustion. Compare:
- Burn stuff, make steam, turn generators, step up voltage, transmit
power many miles over big wires, step down voltage, transmit to
house, and run thru electrical element to generate heat
- pipe stuff to house, burn it, pump hot water around your house.
