11,496 kWh averages nearly 1,000 kWh per month. Thats at or greater than my peak in July with refrigerated air, swimming pool and heavy electronics load.

I could see dropping 10, maybe 20% from my total (gas + electric) before adding generation to offset, but to expect 3 straight years of 15% reductions with just efficiency alone seems a bit of a stretch.
