How do you figure? Bitcoin uses 116 TWh of energy each year, and that number is going up. The US, probably the largest user of Christmas lights in aggregate (probably more than Europe and South America put together, with Asia and Africa having negligible Christmas light usage), used 6.63 TWh of energy on Christmas lights in 2007 when only 5% of them were LEDs, and that number is dropping as people switch to energy efficient LED lights, which use 10% as much energy as incandescent Christmas lights.

That number is way low. I'm guessing it's only looking at indoor lights and not outdoor displays. Holiday lights in the US used 130 TWh in 2016.
Where does that number come from? Mine comes from the DOE. https://www.energy.gov/sites/default/files/maprod/documents/...
