Average $0.21/kilowatt hour (twenty one cents) in the greater SF Bay Area. This can add up to enormous electricity bills for people who live in the hotter areas near SF due to running air conditioners and other high consumption appliances. Additionally, the smart meters bill extra for usage during peak times. We just use passive systems for cooling.
For perspective, our electricity for a 2100 sq ft home is about $75/month. A colleague who lives in a hotter area has an air conditioner and a swimming pool with electric heater ... $500/month just for electricity. I think I have landed on a new definition of insanity.
My wife uses a smartphone app in conjunction with our power company (PG&E) to monitor our usage real time. She is the electricity police in our houese!
Our Christmas lights are regulated on a tight schedule!
