This doesn't matter if you look at a single city. But if you want to look at the lights of a whole country (like I did for the 2012-2016 data here https://t.co/3wU9oU01RH), then the "dark" spaces in between the city become really important.

@MarkGrosz @USGBC And anyway, what evidence is available suggests that the promised environmental benefits of solid-state lighting (through reduced energy consumption) have been largely wiped out by elastic demand for the cheaper light they produce. https:
