So This Is What Darkness Looks Like
At around 8:30, electricity went out in our neighborhood. I walked out on the back porch (we sit on a ridge overlooking much of Erie) and could see that a wide area was without power, but there was still some glow to the north and east over the denser city area. It was the darkest I could recall at this house. My back yard is usually flooded with light from the neighbor who's dog is afraid of the dark (really annoying when I have my telescope out). We pulled out the Scrabble board and started a game by candlelight. There is a gasoline-powered 1500 W generator sitting down in my garage if needed at some point to keep the refrigerator contents from spoiling, but for now I'm enjoying the near absolute darkness that only exists during times like this. The chimes on my hand-made grandmother clock struck 10:00 when I decided to jot down a few notes for this story.
I had forgotten what dark looks like; our only other power failure occurred a couple years ago during daylight hours. It was almost shocking having to feel my way along the walls whilst seeking out a flashlight. Even with heavy curtains, blinds, and shades on the windows, our suburban environment is polluted with so much excess ambient light that you can function to some degree in any room in the house without turning on a light. The amount of light that bleeds through my front door glass is shocking, and this neighborhood is suburban, not urban.
Every house, it seems, has outside lights on from dusk until dawn (mine are all motion-sensing to avoid that). Every parking lot is illuminated brightly enough to read a book by. Kilowatt-level lights illuminate streets and highways. Immensely bright LED billboards flash messages all night long. Commercial buildings are lit to the max around their perimeters, ostensibly for security reasons. This is why I can no longer observe star clusters and nebulae that were visiblemany decades ago when I first entered amateur astronomy as a hobby. It is also a big part of why our power grids are so heavily strained. When I read news reports of the bankrupt city of Detroit turning off a third or fourth of its street lights to save money, I wondered why so many ever needed to be on in the first place. We have resolved to find a home with dark skies.
Interestingly, the level of traffic on my street has dwindled to almost nothing over the past couple hours. I wonder if it because the otherwise drivers figure the stores and their friends' houses have no power either. Or, is it because their automatic garage door openers have no power so they can't get their cars out? It reminds me of a blonde joke about the woman who locked herself in her car and couldn't find her keys.
