There’s something important happening in Tennessee right now, that many people may not have even noticed. When I first noticed, I thought it was just one school, but in the last few weeks I’ve realized, it is spreading all over the place. More and more, all over this town and surrounding areas there are school zone lights, flashing yield lights at intersections, and other types of electric traffic signs all now being run on solar energy.
The first time I saw the tiny solar panel on a school zone light, I pointed it out to my sister and we discussed how cool that was for the school to do that. Then we saw another set of panels on another school zone in another town later in the week and discussed how we were glad to see it was catching on. Not long after that, we noticed that a local by-pass has swapped its hanging electric yield lights at both its major intersections with a new set of flashing lights on poles which have large solar panels on top – and we realized this was happening all around us, not just in one or two isolated areas.
I haven’t been able to find anything in the news about a new solar-powered light initiative in TN, or even any mention of other people noticing them. I did manage to find this article from February, which explains how they are able to make these solar-powered lights possible.
