I think I do the most in my home. Part of the remodeling of our house included new windows (33), doors, and roof, as well as tweaking the gas and AC systems. Energy saving light bulbs, recycle everything: plastic, paper, glass, aluminum, biodegradables. Our gas company sends us a comparable chart for energy usage, to compare to our most efficient neighbors. Well, now I am the most efficient neighbor! Our gas bill has gone from $200+ a month to about $92.00. It makes me laugh because some of those neighbors are quite snobby about their supposed "earth friendly" ways (i.e. some have publicly lambasted DH for driving a SUV). Our thermostat is set on a setback for both heat and AC.
When we had our bathroom totally gutted and remodeled, we didn't get the fashionable soaking tub; hence, I only use one of the other tubs about once or twice a year, and only use the very nice shower in the master bath.
We don't have a lawn (purposely bought this house because of this) and have low water plants and ground cover.
I try to purposely plan all of my driving trips, which has become hard since I started a job where I have to drive to people's houses. But, I get to plan my own schedule, and I schedule my sessions accordingly. I really don't drive anywhere, except to the store, bank, and dry cleaners (3.5 miles), drugstore (5 miles), or to my friend's homes (not more than 6 miles). We do go out to eat a lot, but usually not more than 15 miles away, and when we go into Boston we take the train or share driving with friends for our theatre subscription.
Food, well I buy all local fruits and veggies in the summer/fall, as we have many local farms. I usually do this by bike, too. I admit to buying out of season fruits and veggies, as I take this as something for my health. I also try to shop at independent stores in my town and surrounding towns for gifts, at the many artist's studios we have. I bought both of my bikes at the very local bike store.
Clothing however, and bike parts we do on line. I'd have to travel between 19 and 25 miles to find a Banana Republic Petites store or any other place where I could find clothing that fits me.
When I look at my friends' habits, I'd say I am pretty far ahead. Some don't even recycle that much. I just bought a new car yesterday, that gets about 20% better mileage.
