A string of Christmas lights (100 bulbs) show that each bulb is 6 Watts. The lights are illuminated for a 24 hour period. How many Kwh of power does this represent? If Duke Power charges $ 0.14 per Kwh, what is the cost of burning these lights for the 24 hours?

The total Kwh of power used is 100 x 6 Watts x 24 hours = 14,400 Kwh. The cost of burning these lights for 24 hours is 14,400 Kwh x $0.14 = $2,016.
