137 kWh!

I'm very concerned. While I know most people would be thrilled to get a monthly usage of 137 kWh, (especially because it's from renewable sources making it 4% of the national average) I'm appalled. My last two months have both been 68 kWh, meaning I somehow doubled my electricity consumption from mid-October to mid-November. I cannot for the life of me figure out what happened and I'm really hoping they read the wrong meter (I live in an apartment building with lots of separate meters). Otherwise I'm going to have to run around my apartment searching for the mysterious object sucking away all my power. This is the highest value I've gotten since the first month I moved in over a year ago! I know I've been using my computer a lot, but I don't think its that much more than usual. Heat and stove are gas, so I'm at a total loss. All I know is this chart makes me really sad.
