Worth Knowing
Your electricity bill is energy, not power — it's the appliance's wattage multiplied by hours used, billed per kilowatt-hour. That distinction explains why a low-power device left on constantly (a fridge, a router) can cost more over a month than a high-power one used briefly (a kettle). Spotting the big consumers means looking at watts times hours, not watts alone. Standby 'vampire' loads from idle electronics add a small but genuinely continuous cost.
