The Dark Side of Light Pollution
A single 100-watt light bulb left on 24 hours a day for a year uses the equivalent energy of 714 pounds of coal.
Installing quality outdoor lighting could cut energy use by 60-70 percent, save money, the environment and even our view of the night sky.
In the U.S. alone 30% of outdoor lighting is wasted due to ineffective lighting. This results in $3.3 billion wasted and the release of 21 million tons of carbon dioxide a year.
Research suggests that artificial light at night can negatively affect human health, increasing risks for obesity, depression sleep disorders, diabetes, breast cancer and more.
Artificial light can radically disrupt a large variety of wildlife and ecosystems. These include bird migrations, sea turtles, insect populations, predatory animals, and even amphibians.
The natural night sky is our common and universal heritage, yet it’s rapidly becoming unknown to the newest generations.
80% of Americans can no longer see the Milky Way. The night sky inspires us.
If we lose the stars, we lose our perspective. Astronomers are unable to study celestial objects in urban areas.

According to a 2011 study of London street crime, there is no good evidence that increased lighting reduces total crime.
A 1997 National Institute of Justice study concluded, “We can have very little confidence that improved light prevents crime.”
