I have a 1600 sq. ft. house in central Texas. Standard 2x4 construction. Gas heat, waterheat, and stove. Already switching to compact flouresents as the incandesents burn out. No programmable thermostat but that is because my wife is at home with my daughter.
I can get info for our water, electricity, and gas useage if anybody wants to lend a hand or advise.
What would really be fun is implement some improvments that will save money in the long run with minimal impact on our lifestyle. My wife will be a reluctant partner in this effort so minimal impact on our lifestyle will be essential.
