2017’s Most & Least Energy-Efficient States
Energy is expensive. In fact, it’s one of the biggest household expenses for American consumers. According to the U.S. Department of Energy, the average U.S. family spends at least $2,000 per year on utilities, with heating and cooling of spaces alone accounting for more than half the bill. In 2016, the average consumer spent another $1,900 on motor fuel and oil, though that figure represents a decline in recent years.
The Energy Department estimates that adopting energy-efficient measures in the home could reduce a family’s utility costs by as much as 25 percent, proving that it pays to conserve, especially during a time of increasingly warmer temperatures. As for transportation, the agency found that a more fuel-efficient vehicle could save the average driver about $625 per year.
In order to gauge the impact of doing more with less energy, WalletHub’s analysts measured the efficiency of auto- and home-energy consumption in 48 U.S. states. Due to data limitations, Alaska and Hawaii were excluded from our analysis. Read on for our findings, expert insight from a panel of researchers and a full description of our methodology.

Environmentally conscious practices can help prevent costly damage to the planet — and one’s wallet. To help consumers and governments find ways of reducing their consumption and maximizing their savings, we asked a panel of experts to weigh in on the discussion. Click on the experts’ profiles to read their bios and responses to the following key questions:
- What energy-efficient products for the home offer the best return on investment?
- What is the biggest mistake consumers make when trying to make their homes more energy-efficient?
- Should the government continue to incentivize consumers and businesses to invest in energy-efficient projects?
- Do you expect states to diverge in energy efficiency, with some breaking with the Trump administration in continuing to follow the Paris climate accord?
- What tips can you provide for building an energy-efficient home on a budget?
- What are the best strategies for financing solar panels for the home?
In order to determine which states are doing more with less energy, WalletHub’s analysts compared 48 states across two key dimensions, “Home Energy Efficiency” and “Auto Energy Efficiency.” We obtained the former by calculating the ratio of total residential energy consumption to annual degree days. For the latter, we divided the annual vehicle miles driven by gallons of gasoline consumed to determine vehicle-fuel efficiency and measured annual vehicle miles driven per capita to determine transportation efficiency.
Each dimension was weighted proportionally to reflect national consumption patterns and graded on a 100-point scale, with a score of 100 representing optimal energy efficiency.
Finally, we calculated the total score for each state and used the resulting scores to rank-order our sample. Due to data limitations, we were unable to include Alaska and Hawaii in our analysis.
Home Energy Efficiency – Total Points: 50
- Home Energy Efficiency = Total Residential Energy Consumption per Capita / Annual Degree Days
Auto Energy Efficiency – Total Points: 50
- Vehicle-Fuel Efficiency = Annual Vehicle Miles Driven / Gallons of Gasoline Consumed
- Transportation Efficiency = Annual Vehicle Miles Driven per Capita
