Most & Least Energy-Efficient States (2026)
WalletHub said the study compared home and auto energy efficiency across 48 states, excluding Alaska and Hawaii because of data limits.
- According to a new WalletHub study comparing 48 states, Washington ranks as the fourth-most energy-efficient state, while Oregon holds the sixth-most energy-efficient position.
- Energy efficiency helps households lower costs for electricity, gas, and oil, making it a critical factor for home budgets given the significant amounts families spend annually on these expenses.
- Illinois ranks as the 17th-most energy-efficient state, while Pennsylvania holds the 27th spot; conversely, Texas and Alabama rank among the least energy-efficient states, with Wyoming appearing near the bottom.
- The analysis considered factors ranging from residential energy consumption to how many miles people get per gallon of gas, according to WalletHub's methodology.
- Alaska and Hawaii were excluded from the WalletHub report due to data limitations, as the study focused on comparing home and auto energy efficiency across the remaining 48 states.
