The City of Light dimmed? It’s true. Thanks to a new law, not only Paris but all of France will see its lighting level reduced, beginning this July. Window lighting in commercial buildings and the lights on building facades will be turned off after 1 a.m., and interior lighting in office buildings will be off an hour after the last employee departs.
The new law promises to reduce carbon emissions and save energy -- the annual equivalent of 750,000 households’ worth. Most significant is its potential to turn the tide against light pollution by changing attitudes about our unnecessary overuse of light at night.
