How much does it cost to run a 100 watt light bulb?
So, a 100-watt bulb would only cost $0.84 per hour if electricity cost $8.40 per kWh. In reality, electricity costs somewhere between $0.05 and $0.50 per kWh. So, in this unrealistic problem, the light bulb would cost $0.84 dollars per hour * 4.5 hours to run for 4.5 hours.
How much energy does it cost to leave a lightbulb on?
Let’s say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = approximately 20 cents in one day.
How do you calculate energy usage per light bulb?
For example, let’s find the kilowatt hours (kWh) used for a fixture with three 60 W light bulbs that is on for 8 hours per day. To find the monthly energy usage, multiply the result by 30. Calculate the total lighting cost by multiplying the kilowatt-hours used by the cost per kWh.
How many kilowatt hours (kWh) does a light bulb use?
For example, let’s find the kilowatt hours (kWh) used for a fixture with three 60 W light bulbs that is on for 8 hours per day. Watts = 60 W × 3 = 180 W kWh = 180 W × 8 hrs ÷ 1,000 kWh = 1.44 kWh
