We live in a 1,200 sq foot home and our electricity bill was $240 and natural gas $95. We have 3 people at home during the day doing WFH. We're paying $0.33/KWH (power + delivery). It sounds like your main problem is electric heat. BTW, my son used to live in an apartment in Boston - it was an built in the 1960s with electric heat and his electricity bills in the winter were monstrous. The only consolation is that this time of the year is the worst. Bills go way down in the spring and fall and are only moderate again in the summer if you have air conditioning.

Our kids lived in an apartment that had electric heat when they were in college but utilities were covered in the rental price. It was a 2-bedroom in Lowell back from 2008-2012 and the rent was $1,000. The good, old days I guess. Back when I was renting, the prices were around $300/month.
