The International Dark Sky Association seeks to eliminate all unnecessary night lighting worldwide. Originally their motive was “light pollution.” Now it’s also a horrific waste of energy. A third of all night is wasted, in not being focused or concentrated on the objective surface(s). The U.S. along wastes $3 billion each year on diffuse lighting – ten times that much if all the lights were turned out, like they do in Tucson, Arizona. Why can’t every major city follow suit? Why can’t there be a federal law? How bad is it? Here’s a map of the U.S. at night. Scientists on the International Space Station circle the earth once every 90 minutes; as pro-active as NASA is in environmental issues, how come they’re blind to all the wasted night energy they see, day in and day out?
