Christmas lights suck up a tiny fraction of all the electricity Americans use annually, but it's more than some developing nations consume in an entire year, researchers have found.
El Salvador, Cambodia and Tanzania are some of the countries that use less power than the seasonal lights Americans string up, according to the Center for Global Development.
In an interview with NPR, researcher Todd Moss said that it's a useful comparison because many developing countries face pressure to use more renewable sources of energy.
Though switching to cleaner sources of power is important, Moss said, the graph he developed with Priscilla Agyapong shows poorer countries like Nepal and Ethiopia are just a drop in the bucket compared to the U.S.
"It's pretty rich for me to sit in Washington, D.C., and tell Ghana they can't build one natural gas power plant," Moss told NPR.
Americans' holiday decorations use 6.6 billion kilowatt hours of electricity, which is enough to run 14 million refrigerators, according to the researchers. But that only accounts for 0.2 percent of total electrical usage.
