Dominion North Carolina has put together a calculator to help figure the cost to light your home — but it may fall short for the true holiday fanatic. The app only lets you assume running 150 strings of lights for 24 hours/day — certainly not up to Clark Griswold standards:
Maxing out Dominion’s calculator would mean burning 396 Kwh/day at cost of about $1,300 in December. But it is the holidays, after all, and you could turn the lights off during the day.
National Grid included among its holiday tips a “smart baking” section, and noted that “on average, a whole meal can be cooked in a slow cooker for 17 cents worth of electricity.” The utility suggests using the smallest appliance, pan and burner while cooking to save energy, and notes microwave ovens require less than half the energy of a conventional oven.
And does your neighborhood go all-out on the homefront decorations? A string of lights on the tree or mantle may not draw that much power, but according to National Grid more elaborate decorations come with a cost.
Yard inflatables can which range from simple blow-up cartoon characters to large globes with rotating figures, blowing snow and lights. “Large globes consume about 150 watts per hour, while rotating carousels consume around 200 watts. At 10 hours per day, the total cost of electricity could be $10 per inflatable, per month,” the utility said.
