I've been using my own cloth grocery bags for about 20 years.

There are re-cycling bins at our township hall, so every week I take paper, cardboard, cans, plastic and glass bottles, magazines, anything they allow.

I also donate used clothing to the Salvation Army or another local organization.
We've been changing over to the new light bulbs as the old ones die out.

I use the clothesline for drying except in the coldest part of the winter. We have one of those energy efficient washing machines. Uses 1/3 the water, and just a wee bit of HE detergent.

We recently bought a new car that gets almost twice the gas mileage of the old one. And I plan my errands these days.

We have ground water AC. The water comes from the well, circulates in the coils above the furnace, then the cool air blows through the house. Electric costs are 1/3 what a regular AC would be. The used water has to go somewhere - so it is diverted to an outside faucet, and we use it to water the gardens.
