How much does it cost to keep a porch light on all night?

A porch light typically runs at about 0.72 kWh of energy for the night. Assuming you have a 60-watt bulb turned on for 12 hours, (60x12/1000) multiplied by the cost of $0.11/kWh, you will end up with a nightly cost of $0.0792 or $2.38 a month. May 15, 2022
