My house is very atypical for my area of Michigan. It's all electric with a geothermal ground source heat pump for heating and cooling and electric water heaters. In addition it has (or rather had) two of these geothermal units and two water heaters for two separate spaces. We also have a plug-in hybrid vehicle that we charge at home. Outdoor temperatures in the summer range from mid 70s F to low 100s F and humidity is almost always above 60%, hitting 90% for weeks at a time. Our electric usage in all but the coldest months of the year is around 2200kwh per month. I expect this to go down somewhat because we just upgraded one of the geothermal units and replaced the other with a gas furnace and inverter AC unit.
