Something (a lot of things, actually) is/are very wrong. Electrical rates in Oregon are among the lowest in the country, with much of the power being generated by hydro (dams). Where in Oregon are you? We're an hour from the coast, and live in a leaky, 70-year-old beater with mostly junk windows and poor insulation (none in crawl space). Our electric bill is on the budget plan--$114 every month, which I think is quite reasonable. Request an energy audit by your local utility district--they used to be free, and will tell you precisely where the heat is escaping.
Sounds like your furnace or heat pump needs replacing--they are often only good for 15 years of steady use. Double front door is a definite heat-waster, and should be replaced with a new single. A good set of glass doors on the fireplace will also help, as many dampers are leaky affairs even when closed.
