global light pollution Readers of this blog have heard us rail against light pollution countless times. The resource and financial waste is associated with this global problem are monumental. What positive things could we do with all those wasted energy resources? How about power a fleet of clean running electric vehicles?

I read an interesting article the other day entitled “Night Lights and Chevy Volts“. In it, author and night sky activist John Gilkison did a bit of number crunching. What he came up with was the following. By simply replacing the inefficient cutoff lights currently in use (which shine a significant amount of light up into the night sky) with full cutoff lights (which shine no light up into the night), we could reduce the energy consumed by outdoor lighting by approximately 30%. Additional savings could be achieved by eliminating unnecessary light fixtures and reducing operating times of many others. This could push the us closer to a 50% energy savings. This amounts to an astounding 25-30 GWh/year (giga-watt hours). Using the new Chevy Volt as our baseline, we would need 2,600 KWh’s a year for 10,600 miles of electric powered driving. John’s calculations revealed that we could power almost 10 million electric cars for a year for a total of about 10 billion passenger miles! This is astounding. We could quickly make a large dent in our consumption of fossil fuels while also significantly reducing the amount of global warming gases emitted into the atmosphere. These are real and significant benefits. Benefits which are readily available to us. All it takes is the will to act.
