The Good, The Bad, and The Illegal
Lights at night as seen from space above the United States.....
Lots of energy (and money) is wasted by all this light shining upwards
and by inefficient lamps and fixtures which generate a lot of it.
Billions of dollars are wasted lighting up the sky and blinding us with glare.
Replacing Bad fixtures with smaller and more energy efficient ones costs
less than continuing to pay for Bad and inefficient lighting.
