Question 1

What is the average US electricity bill?

Accepted Answer

About $137/month or $1,644/year as of 2024 (EIA data). This varies dramatically by state — from ~$90/month in Utah to ~$180/month in Connecticut.

Question 2

What appliance uses the most electricity?

Accepted Answer

Heating and cooling account for 45–50% of the average bill. After that, the electric water heater and clothes dryer are usually the biggest single consumers.

Question 3

How can I lower my electricity bill?

Accepted Answer

Target the biggest consumers first. Switch to LED bulbs (saves $5–10/month), use a programmable thermostat (saves $10–20/month), run full loads in washer/dryer, and unplug standby electronics.

Question 4

Does unplugging devices save money?

Accepted Answer

Slightly. Standby power ('phantom load') accounts for 5–10% of home electricity use — roughly $7–14/month. Unplugging or using smart power strips helps, but it's not where the biggest savings are.
