Whether you''re using 855 kWh monthly like the average American home or significantly more due to your climate and lifestyle, our
If you're wondering how many kWh a house uses per day, you're not alone. According to data from the U.S. Energy Information Administration (EIA), the average home in the United States uses 855 kilowatt-hours (kWh) per month.
The average American home uses 855 kWh of energy per month or about 28 kWh per day. Based on average electric rates and household energy consumption, the typical monthly electricity bill costs $136. Homes in Louisiana use the most electricity, while homes in California use the least.
Meanwhile, it's normal to around 23 kWh per day in the Northeast and West, where more moderate climates require less energy for heating and cooling. Of course, climate conditions and daily electricity usage vary within each region. Use the map below to see the average daily kWh consumed in each household in your state.
If your home uses about 1,000 kWh per month, that adds up to roughly 12,000 kWh per year. To estimate the system size, divide your annual usage by the average daily sun hours in your region, for example, 4.5 hours per day. That gives you 12,000 ÷ (4.5 x 365) = approximately a 7.3 kW system.
