It’s never a pleasant surprise when your bill seems higher than normal. Making comparisons is difficult because everyone uses electricity and water differently. But comparisons aside, the cost of heating your home increases as the outside temperature in winter drops. The extent that this affects your electric bill depends on your lifestyle and how energy efficient your home was built: i.e., insulation values of walls, ceilings, floors, doors, windows, skylights; type of heating system; amount of air infiltration; solar orientation; and floor space or volume of your home.
