How Much Power Does Your House Really Need?

How Many Watts Does an Average House Use

Ever wondered how much energy your cozy house gulps down? Turns out, measuring its appetite in watts is like trying to explain a rollercoaster to a hamster – not quite the right tool.

But fear not, curious homeowner! We’re about to untangle the watts from the watts-hours and kilowatt-hours to answer the burning question: how many watts does an average house use?

Watts vs Watt-hours: A Quick Detour

Imagine watts as the speed of your house’s energy guzzler, while watt-hours are the total distance it travels. So, a 100-watt light bulb shining for an hour uses 100-watt hours of energy. Got it? Great! Now, let’s zoom in on..

Average House Energy Consumption: Watts by the Hour, Day, and Month

Time PeriodWattskWh


  • This table represents the average energy consumption of an American home. Individual houses may vary significantly depending on factors like size, climate, appliances, and occupant behavior.
  • “Watts” refers to the instantaneous rate of energy use, while “kWh” (kilowatt-hour) is a unit of energy consumption over time. 1 kWh is equal to 1,000 watt-hours.

I hope this table provides a clearer picture of how average house energy consumption breaks down across different time scales. By understanding these numbers, you can better assess your own home’s energy needs and identify areas for potential savings.

How Many Watts Does an Average House Use

How Many Watts Does an Average House Use

The average American home, according to the Energy Information Administration, sips up around 10,791 kilowatt-hours (kWh) of electricity per year. Whoa, that’s a big number! But don’t panic, because a kilowatt-hour is like a giant bucket of watt-hours, holding 1,000 of them. So, to find out the average hourly wattage, we just divide:

  • 10,791 kWh / 8,760 hours/year = 1.22 watts per hour

That’s right, the average house hums along at a surprisingly low 1.22 watts per hour. But remember, that’s just the average. Like snowflakes and kids’ socks, no two houses are exactly alike.

Factors that Fuel Your House’s Appetite

  • Size matters: McMansions naturally crave more energy than cozy bungalows.
  • Climate control: Air conditioners and heaters are power-hungry beasts.
  • Appliance age: Newer models are often more energy-efficient.
  • Lifestyle habits: Marathon gamers and baking enthusiasts, beware!

The Daily Dose of Watts

While 1.22 watts per hour might seem like a trickle, it adds up over the day. To get a better picture, let’s break it down:

  • Average daily watts: 1.22 watts/hour * 24 hours/day = 29.3 watts
  • Average monthly watts: 29.3 watts/day * 30 days/month = 879 watts

So, there you have it! The average house uses around 29 watts per day and 879 watts per month, with the actual number depending on the factors mentioned earlier.


Understanding your home’s energy needs is the first step toward saving money and reducing your environmental footprint. By making small changes, like swapping out old appliances for energy-efficient models and unplugging unused electronics, you can power down your watts and feel good about doing your part for the planet.
