With snow falling and temperatures dropping, the holiday season is upon us. In the movie "Christmas Vacation" Chevy Chase's character attaches thousands of Christmas lights to his roof with a staple gun. When the lights go on, utilities have to boost their power to avoid a blackout. That would not happen today. Online stores like Lighting Ever
are selling more LED lights this year, which use less energy.
As these lights grow cheaper, Wal-Mart says it will devote half its Christmas light shelf space to LED's. These energy-efficient holiday lights can save over 90 percent on energy costs versus the old-style incandescent lights.
