If you envision having the best lighted holiday display on the planet this year, Duke Energy can tell you how much you’ll likely spend on electricity.
The utility’s Holiday Lighting Calculator lets you enter the kind of lights you have and how many strings you plan to use and then tells you what all that light’s probably gonna cost you.
Say you want to outline your house in lights, and you want to turn them on 7 hours a night for a month.
According to the calculator, the energy needed for 20 100-bulb strands of 2 inch LEDs will run you around $42. But, that same number of old-fashioned, incandescent Christmas lights would cost you $294.
North Carolina-based Duke Energy has more than 1.5 million customers in Florida.
