Quick questions
Short answers to keep things light.
Could my meter be faulty?
It's possible but less common than a routine change, rate change, or longer billing cycle. Rule those out first, then request a meter check or re-read.
Why is my bill higher in summer or winter?
Cooling and heating are among the heaviest electrical loads. Seasonal peaks are normal and usually return to baseline once the weather eases.
What is an 'estimated' reading?
When the meter isn't physically read, utilities estimate usage. A later actual reading can correct the difference, sometimes causing one higher bill.
How can I find what's using the most power?
Compare bills over time, check for new or always-on devices, and use a plug-in power meter or your utility's usage data to pinpoint heavy loads.
Is the analysis on this page official?
No. It's an educational estimate to help you reason about your usage. Only your utility's metered bill is official.
Is an electric shower cheaper than a tank heater?
It depends on use. An instant shower only draws power while running but at very high wattage; a tank loses some standby heat but can be efficient if well insulated. Usage pattern matters more than the type.
