How much does it cost to leave a 60-watt light bulb on for 24 hours?
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 does it cost to leave a lamp on all night?
A “normal” incandescent bulb costs about 0.75cents per hour, and LEDs or CFLs cost only one-sixth of that – so leaving the lights on (either overnight or while you’re at work for the day, say both are about 8 hours) costs you roughly 6 cents for a normal light and a bit over 1 cent for modern bulbs.

How much does it cost to power a light bulb?
For this infographic we are using an average cost of electricity per kWh of $0.11, and since a 100-watt lightbulb uses 0.1kWhs worth of electricity per hour, weve concluded that to power that lightbulb for 8,760 hours (1 year) it would cost $96.36. Just ONE lightbulb could cost you almost $100 per year.
What uses a lot of electricity?

Depending on the efficiency of your unit, in a 24-hour period, your HVAC could use around 28-63 kWh, resulting in about 850-1,950 kWh in a month.
Do night lights use a lot of electricity?

Are lamps more energy-efficient?
While the answer will vary with the bulb, the cost of the energy of a light left on, especially, is fairly low no matter what bulb you’re using. Energy.gov says that today’s more energy-efficient bulbs typically use 25-80% less energy than traditional incandescent bulbs and that they last 3-25 times longer.
