A 33-day bill looks larger than a 28-day bill, even if your daily use did not change. A kilowatt-hour is the energy used by a 1,000-watt appliance running for one hour. The formula is: watts x hours used / 1,000. A 100-watt bulb for 10 hours uses about 1 kWh, and a 1,500-watt space heater for two hours uses about 3 kWh. Compare kWh, not just dollars. Flat kWh with higher dollars means a rate or fixed charge changed, while jumped kWh means something used more energy.
