(NEWSER) – America's Christmas lights, even those that don't rival the Griswolds, guzzle a staggering amount of electricity when compared to power use in other countries, according to researchers at the Center for Global Development.

The festive lights use around 6.6 billion kilowatt-hours a year, according to the CGD—more than the total annual electricity consumption of countries like El Salvador, Cambodia, or Ethiopia, which has a population of 94 million. The researchers, who used data from the World Bank and a 2008 US Energy Department study, say Christmas lights only account for 0.2% of America's electricity usage, but the power is still enough to run 14 million refrigerators.
