FAQ

Is 970 kWh/month a realistic estimate?

This is the U.S. national average for a home of this size per the EIA Residential Energy Consumption Survey. Real usage varies significantly by climate (Sun Belt homes ~30% higher due to AC; mild-climate homes ~30% lower).

What if my home is all-electric (including heat and water heat)?

All-electric homes typically use 40-60% more kWh than the estimates above. A 3-bedroom home with electric heat and electric water heater in California might use 1,400-1,700 kWh/month rather than 970.

Does this include natural gas?

No. This is electricity only. If you also have natural gas, expect an additional gas bill of $30-$120/month depending on climate and appliances.
