I hope many cities and towns participate in “Lights Out” this fall in North America.

Natural History Wanderings

EnvironmentalNews Network reports that France is implementing one of the world’smost comprehensive “lights out” ordinances. It includes

  • turning off shop lights between 1 a.m. to 7 a.m.,
  • shutting off lights inside office buildings within an hour of workers leaving the premises
  • waiting only until sunset before turning lights on, on building facades.

Benefits of the ordinance include:

  • cut carbon dioxide emissions by 250,000 tons per year, conserve energy consumption, and cut the country’s overall energy bill by 200 million Euros ($266 million).
  • a reduction in the disruption of natural patterns of light and dark, and thus the structures and functions of ecosystems, is having profound impacts.
  • less disruption of  patterns of mating, migration, feeding, and pollination, (leatherback turtles,birds, bats, moths, and even salmon, are affected by man-made light)
  • improved star-gazing for astronomers and the public
