On the East Coast, there was more dimming, which the researchers attributed to the use of energy-efficient lightbulbs and &#8220;broader economic restructuring.&#8221;\u00a0<\/p>\n<figure class=\"embed embed--type-image is-image embed--float-none embed--size-medium\">\n<p>      <span class=\"img embed__content \"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/05\/15\/011bf8d4-721b-419d-8048-0dfcf126b5c5\/thumbnail\/620x413\/91c5d60d059404ec850d912f4e43d2c1\/nightlights-global-20142022.jpg#\" alt=\"nightlights-global-20142022.jpg \" height=\"413\" width=\"620\" class=\" lazyload\" srcset=\"https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/05\/15\/011bf8d4-721b-419d-8048-0dfcf126b5c5\/thumbnail\/620x413\/91c5d60d059404ec850d912f4e43d2c1\/nightlights-global-20142022.jpg 1x, https:\/\/assets2.cbsnewsstatic.com\/hub\/i\/r\/2026\/05\/15\/011bf8d4-721b-419d-8048-0dfcf126b5c5\/thumbnail\/1240x826\/3cb79858ceb8e41c1b315daebd1dd7d1\/nightlights-global-20142022.jpg 2x\" loading=\"lazy\"\/><\/span><figcaption class=\"embed__caption-container\">\n<p>                  <span class=\"embed__caption\">An analysis of the Black Marble data collected by NASA.
