How much would it cost if I left a light 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.

The amount of electricity consumed to supply the inrush current is equal to a few seconds or less of normal light operation. Turning off fluorescent lights for more than 5 seconds will save more energy than will be consumed in turning them back on again.
Put simply, turning these lights on and off won't affect your energy bill from utility providers and electricity companies that much. Just remember, these types of bulbs have an operating life. This means their lifespan can be extended by reducing the amount of times you switch them on and off.
As a homeowner, turning the lights off when you're not using them can help save money by reducing your electricity bills, extend the life of your light bulbs, and buy bulbs less often. Turning your lights off is essential when you go out of your room for a few minutes. Doing so can make your home more energy-efficient.
