This week's minor lifestyle modification proves that every little bit counts. Though I had already been using energy efficient lighting outdoors, switching to a solar-powered alternative helps not only reduce my consumption of electricity, but also helps curb my contribution to a mounting problem of light pollution. Based upon our earlier calculations, I'm updating our tally this week to reflect an additional yearly savings of 75 kWh per month.
Light pollution is, of course, not endemic to south Florida. Rather, our ravenous need for outdoor illumination is prevalent across the United States and the world. Several of my colleagues continue to work on this issue elsewhere. Take, for example, this special forces team otherwise known as the Dark Rangers.
