How we computed it
- Take EIA's average residential price for each state in 2025: revenue from home customers divided by the kilowatt-hours they bought.
- Sort the 51 values. Highest: Hawaii, 40.59 cents. Lowest: North Dakota, 11.81 cents.
- Divide the highest by the lowest: 40.59 ÷ 11.81 = 3.44.
- Multiply each price by 10 kWh and divide by 100 to get dollars: 40.59 × 10 ÷ 100 = $4.06 for Hawaii.
- Count states above the U.S. average of 17.30 cents: 17.
Formula: ratio = highest state price / lowest state price = 40.59 / 11.81

CSVWhat this does not show
A price per kilowatt-hour is not a bill. Homes in cheap-rate states often use more power. EIA can revise 2025 figures when its final annual data comes out.
