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.
An average 60W bulb will cost around $2.70 to purchase. Let's say that in one year, you used this bulb for 1,000 hours at a rate of $0.11 per kWh. In 10 years, operating this bulb would cost you $66.
Incandescent Bulb: A 60W incandescent bulb running for an hour uses . 06 Watts – which costs 0.06 X 5 =. 3 rupees per hour, or 30 paise per hour. Assuming that it is on for 3 hours a night, it costs around 90 paise per day – or 90×30= Rs.
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.
So, a 60-watt bulb uses 60 watts hours or . 06 kilowatt hours of energy for each hour it's on. The bulb would use 1 kilowatt hour in just less than 17 hours if left on continuously, around 12 cents in our current tariff for most residential customers.
You should leave the lights on because it takes more energy to turn them back on than you'll save by turning them off. FALSE! Fluorescent lights do take a small surge of power when turned on, but this is significantly smaller than the amount saved by turning them off.
