I got my Duke energy bill yesterday. My electric usage continues to be much, much lower than last year. I did have 3 more people here last year though. The one point I would like to make about that though is that none of them really ran the air conditioner more than I would have. My sister and her husband got cold in my house and my brother lived in the basement which is substantially cooler than upstairs. There were 3 TVs in the house at that time that was probably a significant energy drain. I don't have a TV. Also my computer and my router are on switches that are turned off when I am not using them.
Anyway, here are the numbers from June which was a very hot month. Days were often right at or above 100. I was very comfortable in my home.
Usage less than half compared to last year. I am very pleased with that and the improved comfort level.
