I recently interviewed a local astronomist who said, these days, that we’re absolutely awash in “light pollution.” And yeah, light pollution diminishes night visibility for astronomers, and such, but it’s way more than that. According to www.darksky.org, about 15 million tons of carbon dioxide are emitted each year in America, just to power outdoor residential lights. That equates to the emissions of about three million autos and adds up to 40,000 tons of CO2 a day. (And this is just residential lighting. It doesn’t include business lighting.) The organization also explains to offset this amount of CO2, the U.S. would have to plant 600 million trees annually. As president, I’d advocate for a department that specifically dealt with light pollution, given what a big problem it’s becoming. For more about our position on energy, go to… Note: This astronomer told me that one of the biggest light wastes can be found in many of our municipalities’ street lighting. Instead of streetlights with “down-shine” fixtures just to train the light down, many streetlights (like the one in the photo above) disperse light sideways and up — neither of which is necessary — and a tremendous waste of energy.
