Also I know in my area, and I'm pretty sure just about every place in the US, charges more for electricity during the summer.
So, yes, in that case my electricity bill has gone up this year, also because I am using the AC now.
I had assumed Back was comparing this year to last year, but perhaps this is Back's first time ever paying an electric bill in his life and he doesn't realize that summer rates + AC usage = higher electric bill.
