I'm not doing much that I haven't always done.
High efficiency heat pumps.
All lights that run duty cycle are compact fluorescents.
I ride my 50MPG motorcycle everywhere I go , weather permitting.
When I got my last car (1997) I choose a car with a rating of 30MPG, not a gas guzzling SUV. I try to drive it a minimum (so far 52,000 miles).
Left to me, I would seldom eat out, but the wife only wants to eat out, so we waste a lot there.
If I want to buy some expensive toy, I work at a part time job to pay for it, no long term debt .
I try to do all the repairs needed around the house, I do my own electrical, and plumming. If one of my A/C needs freon, I do it myself, car or house.
Although I hate doing mechanic work on the car, I will do it if necessary, except I found out it dosn't really cost much more to have WalMart change my oil, so I let them do that.
I cut my own grass, and do my own lawn work (such as it is)
However, if I need a roof, I call our roofer.
