Frequently Asked Questions
How is my electricity bill calculated?
kWh used × your rate. The US average is about $0.16/kWh, but ranges from $0.10 to over $0.40 by region. Time-of-use plans charge more during peak hours.
How do I figure out an appliance's monthly cost?
Watts × hours/day × 30 / 1000 × rate. A 100 W TV running 5 hours daily at $0.16/kWh costs about $2.40/month.
Which appliances use the most electricity?
Heating/cooling (HVAC), water heater, electric dryer, oven, and EV charging dominate. LED lighting and modern electronics are minor by comparison.
Does standby (vampire) power matter?
Yes - typically 5-10% of a home's bill. Game consoles, set-top boxes, and old chargers can each draw 5-20 W constantly. Smart strips help reduce this.
