How many kilowatts does it take to run a house
A small home in a temperate climate might use something like 200 kwh per month, and a larger home in the south where air conditioners account for the largest portion of home energy usage might use 2,000 kWh or more. The average U.S. home uses about 900 kWh per month. So that’s 30 kWh per day or 1.25 kWh per hour.
How do you calculate kWh per day
One kilowatt is equal to 1,000 watts, so to figure out the kWh per day that your refrigerator uses, you simply need to divide the watt-hours per day (7,200) by 1,000 for a total of 7.2 kWh per day.
Is 50 kWh a day a lot
This too varies depending on the size of the solar array you’ve installed on your home, where you live, the weather, and many other factors.
