Put plastic over your windows to keep out drafts in winter. Put a rolled towel at the base of your front door to keep out drafts. Close the curtains during the day in the summer to help keep it cooler.
Also, get power switches for electronics and turn the switches off when not using them. Many devices such as tv, cable boxes, dvd players, etc don't actually quit drawing power when you turn them off. They go into standby mode which still uses a fair amount of power (sometimes called phantom use). You can get a device called a Kill-A-Watt that you plug items into and it shows how much power they use. We were very surprised and now use power switches for most things. That has really helped.
Energy efficiency. The thing you will soon understand very well. Double paned glass, weather-stripping, caulked windows and all wall/floor cracks, energy efficient AC and heater, stove must be energy efficient, frig energy efficient, light bulbs must be energy efficient. Insulation in the walls and roof/ceiling. Even insulation in the electrical outlets. So you get the idea. Make sure your electric meter is correct too. Sometimes a neighbor may be draining off of you.
Would also find out what the previous owner paid. The utility company can look that up.
Have the utility company come out and check your meter. I lived in a rental for 3 yrs back in the 80's and it turned out we had the opposite issue- our bills were less than they should have been because the meter was not working properly and they wanted us to pay hundreds of dollars to make up the shortage.
No one can answer that since everyone's usage is different based on their lifestyle. Also, the rates vary depending on what your provider's rates are and the taxes in your area.
You can call the provider and ask that they perform an energy audit on your property. That will help you find out where power is being wasted
The answer has a lot to do with where you live and the weather conditions. If not in a temperate area...and, as you say, everything is electric,,heating costs could be substantial...Yikes!! On the other hand, sometimes power companies make mistakes.
My neighbor..in a nearby apt (downtown L.A.)...had a last month's light bill...of $528, when the usual is less than $20 (turned out to be a DWP computer glitch). I had fun ribbing him about having left the x-ray machine on overnight, running a commercial printing operation, and cannabis farm, jazz club and whiskey distillation operation down in the basement. ; )
generally when all utilities are electric the rates are lower than if they were part gas and part electric
if you are not using the AC(in the winter of course) you are using heat and it is very possible you are not careful about turning off electric things you are not using
Electric rates vary with locality and you can't control the rates. With an all-electric house, of course your electric bill will be the largest utility item.
Look at your electric USAGE (kwh) now compared to the past two years. Usage is something you can work on.
Our electric has been high for the last 2 years. We had a bill that was $667 over the winter. We just got one today and I'm happy that is it only $150 but that's without running the central air at all! The house has zero gas, everything is electric... So is that reasonable or is it too high? Sewer was $15 and water was $17, trash pick up is $11 and electric tax is $2.50... That means just the electric is $104.50 (if I did my math correct)
