How much heat does a 60 watt bulb give off?
A standard 60 W lamp produces 60 W of heat per unit time. In other words, in one hour a 60 W lamp produces 60 Watt-hours. The conversion for watts per hour to BTUs is 3.412 BTUs per Watt-hour so a 60 W lamp produces (60 x 3.412) BTUs or 204.72 BTUs.
How much does it cost to leave a 60 watt light bulb on all day?
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 much energy do you save per hour if you replace a 60 watt light bulb with a 55 watt light bulb?
The difference is (60 – 55) = 5 watts = 5 joules per second. (5 joule/second) x (3,600sec/hr) = 18,000 joules/hour. (5 watts) x (1 hour) = 5 watt-hours = 0.005 Kilowatt-hour.
Does it cost more to leave a light on or turn it off?
