Night-Sky Light Pollution -- Satellite Imagery Confirms What We Already Know

Five years of advanced satellite images show that there is more artificial light at night across the globe... And that light at night is getting brighter. The rate of growth is approximately two percent each year in both the amount of areas lit and in the radiance of the light. As streetlights the world over change from sodium lamps to LEDs, scientists wonder what this means for night skies. Scientists are finding that much of the financial savings derived from the improved energy efficiency of outdoor lighting is being wasted in the deployment of more lights. As a result, the projected large reduction in global energy consumption for outdoor lighting is not being realized.

What a shame....We have the technology and the know-how. If only we would use them wisely, we could have lights and beautifull skies at the same time and everybody wins.
