Wal-Mart Saves Energy

I went to the real grocery store Monday night. When I got to the freezer section, the lights were off. I just thought that they must need to change the bulbs, but how odd that an entire row would go out all at one time. As I turned down the aisle, the lights came on as I walked by them. It was like that on the next aisle, too. So the lights turn off when nobody is around, and then they have sensors so that the lights turn on when there is movement. I think it’s a good idea. Does anyone else have this at their grocery store?
