Sorry, I forgot to mention electricity. That bill is usually about $170 average. Half the 150 lights are cfl. All of them would be, but my wife hates their color. In the summer we don't run the air except for the upstairs, which is set at 65 degrees (no, that is not a typo) from 9 pm until 6:30 am.
Because my mother-in-law is a German from pre-WWII Ukraine, she has issues with saving food, so she has two full sized fridges just for herself and any guests she has. She also likes to open her windows for an hour a day with the heat/air running to get the "bat air" (<--German accent for "bad air") out of the house. (Yeah, I know, it's crazy, but you gotta be nice to a 89 year old lady, right?)
