I'm about 5 minutes north in San Carlos and I'm spending $50/month. My apartment is poorly built (gets up to 80 F when it's only 60 F outside, no idea what's up with that), however I try to avoid running the A/C and it's still that high. My Mac Mini and a couple of external hard drives are always running but otherwise I'm surprised at the energy usage.
