It's a lot less than you might think. First of all, the majority of our display is LED lights, which take a fraction of the power of the standard lights we used to use in the early days. Secondly, since most of the display is computer-controlled, typically at any moment in time, only a fraction of the total lights are on at the same time, which helps keep the overall number of lit lights much lower than if we ran the entire display as "static".
