Shedding Light on Electricity Usage

We’ve put together key info and insights to help you better understand your home electricity usage and what impacts it.

The National Average

On average, U.S. households use approximately 10,715 kWh of electricity per year, according to the U.S. Energy Information Administration. That’s 893 kWh per month. While your usage depends on many factors, an above-average rate can be a sign to cut back.

Turn off and unplug anything that doesn't need to be on

For example, computer monitors and printers still draw power in standby mode and wall warts can draw “vampire power” from an outlet even if they’re not powering anything. To help you manage many devices at once, try smart plugs or surge protectors.

Switch to energy-efficient appliances, lighting, and electronics

While appliances are a major expense, smart thermostats, smart plugs, and LED light bulbs are affordable, efficient, and easy to use.

Shop around for a better kWh rate.

How We Crunch the Numbers

1

We estimate every home's electricity usage based on data from a number of public and private data sources, including your electricity distributor and the Department of Energy.

2

We overlay key information about where you live, including weather and climate data about your region, and housing data like when your home was built and how big it is.

3

To figure out your home's carbon footprint, we look at how electricity is generated in your state, like whether your electricity is coming more from coal (very carbon-intensive) or wind (carbon-free).

Using this data-driven approach, we have created a machine learning model that can estimate electricity usage and carbon footprint for every home in the US. We then use this information to recommend the best options for you, so you can feel good that WattBuy is recommending something truly personalized.

Our electricity estimations are trusted by our partners at The Department of Energy's National Renewable Energy Laboratory, as well as many of the biggest consumer brands in the world.
