Frequently Asked Questions (FAQ)

Q: How can I find my electricity rate per kWh?

A: Check your utility bill for the "Rate per kWh" or "Energy Charge." It's usually listed clearly on the bill breakdown. You can also contact your utility company or check their website for current rates. Average US residential rates range from $0.10 to $0.20 per kWh depending on your location.

Q: What are the most expensive appliances in my home?

A: Typically, air conditioning, electric water heaters, and electric ovens are the biggest consumers. Use the electricity bill calculator above to identify your specific high-usage appliances. Central air conditioning can account for 30-50% of summer electricity costs in many homes.

Q: How much can I save by switching to LED bulbs?

A: LED bulbs use about 75-80% less energy than incandescent bulbs and last 25 times longer. For a typical household with 30 bulbs, switching to LEDs can save $50-100 per year on lighting costs alone. The calculator above can help you estimate your specific savings.

Q: What is phantom load or vampire power?

A: Phantom load is the electricity consumed by electronics when they're turned off but still plugged in. Devices like TVs, computers, and chargers continue to draw small amounts of power. Unplugging unused electronics can save 5-10% on your electricity bill.

Q: Should I switch to a time-of-use rate plan?

A: TOU plans can save money if you can shift major usage to off-peak hours. However, if your usage is already mostly during off-peak times, you might not see savings. Use the calculator to model different scenarios and check with your utility for specific rate structures.
