Home Energy Costs Insights

Residential Time-of-Use (TOU) utility rate plans with a 2.5x peak-to-off-peak price spread (32.00¢/kWh peak vs. 12.80¢/kWh off-peak) create major household bill savings opportunities. Shifting heavy appliance cycles—such as electric clothes drying (4.0 kWh/load), dishwashing (1.5 kWh/load), and EV home charging (30.0 kWh/session)—outside peak hours saves $0.77 per dryer load, $0.29 per dishwasher cycle, and $5.76 per EV charging session. A household executing 16 dryer loads, 25 dishwasher loads, and 10 EV charging sessions off-peak achieves $77.09 in monthly utility bill reductions ($925.08 annually) without altering overall energy consumption.

At the EIA May 2026 U.S. residential average of 18.44 cents/kWh, adding 40 kWh to an EV battery models to about $8.20 from the electric meter when charging losses are estimated at 10%. A 30 kWh/100-mile EV benchmark works out to about $6.15 per 100 miles before utility fixed charges, taxes, riders, and time-of-use details.

EIA reported 106,659 million kWh of U.S. residential electricity sales in May 2026, up 1.7% from May 2025. The same May 2026 update said cooling degree-days increased in 38 states and the District of Columbia, making this a useful early-summer signal for households tracking air-conditioning-driven bill changes.
