For nearly 40 years, Dick Norton and his family in Burbank, Calif., have pulled out all the stops to create this winter wonderland, complete with a combination of digital displays and analog props, including a North Pole Express train that emits steam, an animated merry-go-round, Santa’s Toy Shop, and 10,000 lights. The display is a thing of wonder to be sure, but paying for the juice to run the elaborate attraction — even with the inclusion of a few LEDs — probably isn’t as wonderful.

  • Estimated cost (lights only): $7.50/hour; keeping them lit for 4 hours a night over 30 days adds up to $900/month.
  • Estimated cost using only LEDs: $1/hour; $120/month.
  • Possible electric bill savings: $6.50/hour; $780/month.
