Duke Energy has some suggestions to help everyone be safe and save money as they decorate for the holidays.

On average, holiday lighting costs just pennies a day.

However, elaborate displays that use large incandescent bulbs can add as much as $80 to a monthly power bill, depending on the number of bulbs and how long they are lit each day.

The same style bulb that uses a light-emitting diode rated at 65 watts would increase the electric bill by only about $7 a month.

Using mini lights will reduce the cost increase even further -- to about one-dollar a month.

To help customers estimate their holiday lighting costs, Duke Energy has added a calculator to its website.
