Not to mention more people die of cold than do from it being hot...

Some sites try to fool you by adding in the cost of carbon to the equation, but that doesn't help you pay the bill when it comes due...
Electric heating is both inefficient and costly. It's fine if you live somewhere like Phoenix where I do and use a heat pump (A/C run in reverse). The coldest days barely reach freezing and are few. Most of the time, you are in the 50's or 60's during the winter.
But live somewhere where it gets really cold and your electric bill can easily top $1000 a month for heating.
