I distracted myself from the point I had planned to make, that was partially illustrated above by others. Some of the alternate choices as light sources are no better, production and world-impact wise, as turning the lights on. While you wouldn't (I hope) light enough candles to be the equivalent of the light bulb, that candle wasn't produced without any impact.

The grocery store is a good place to look at for poor environmental practices, but we created them ourselves (partly). The stock on the shelves, the infinite variety of scents and colors, all of this stuff is purchased by the store wholesale and sold retail and if it doesn't sell it goes to someplace downscale that sells this stuff discounted retail. But they have a lot of stuff, so if they don't sell it, where does it go? What does the world DO with all of the silly lotions and flavors and plastic trinkets that are meaningless and non useful? Between over production on things we don't need instead of making a few practical varieties, we have manufacturers creating stuff then trying to create a need (for their bottom line) and we go for it. We encourage them to keep doing it.
