Are you sure you're calculating that correctly? The average household across the entire US is 10mWh/year (i.e. 10,000kWh/year), and I'd imagine living in Arizona with the extra AC usage would bump that up a bit. That and given you have two AC units with a pool, using only a fifth of the average seems like a stretch.
My personal electric bill in the middle of the summer peaks at nearly 5mWh just for the month...
