Eliminating Light pollution from all government outdoor lights can save a lot of energy. Using the proper fixture, and high efficiency lamp can save over 50% of the energy in some cases and still do a better job. All new outdoor lighting should be required to be fully shielded. Put the light where it is needed and not into the sky. Although retrofitting existing lighting takes time to pay back, the reduction of energy consumption and green house gases is immediate. Youth will be inspired to explore space when they can see the stars again.
