Night light by ward
Light seen from space at about 1:30 in the morning: the night-time radiance and lit share of every 2026 ward, municipality, district and province each month since January 2012 and each year, from NASA's Black Marble (moonlight, cloud and stray light corrected by NASA). Shown as light, by ward and year; it can't tell grid from solar, or who pays.
