Utility Check

So although the actual experiment won't "really" start until November, I best get into the habits of detailing funds now: $113 in utilities: electricity, water, and internet. (No TV hookup, no gas because all-electric appliances). This is for September 2011, which still had 110-90 degree weather for most of the month. Now that it's much cooler, we've turned the thermostat higher so hopefully that should lower costs a bit. Goal: under $100 for October's bill. Would a microwave help? (No, says Scientific American. Best cut costs elsewhere.)
