How many kWh monthly?

Let's say your overall rate is $0.50/kWh, that would put you at 1500kWh per month. Which is....high. Even if your rate were $1/kWh, 750kWh would be a decent amount of juice for a region with an overall mild climate.

The EIA[0] says the typical annual electricity consumption for homes in "the West" (ie not just California) is 8525kWh/year, or 710kWh/month.
