We have wood furnace in the basement with Oil back up and a wood cook stove on the addition (that can be closed off from the house). We had already been doing the errands all at once, you have to think about it, but do errands on one side of the street, then turn around doing errands on the other side of the street, head home.
I keep an extra loaf of bread and oleo in the freezer so if we run low for any reason.
Also using a gas push lawn mower instead of the cub cadet. I need the exercise and letting the real gas hog rest for most of the summer, the chickens are penned in around the garden for insect and grass control.
We live in a town that recycles so that has been done for many years, avoid spray paints etc, use pump chemicals for the hair to be under control.
In the summer, we can or freeze all we can, example, tomatos are $2+ a can, we can buy (although we grow) tomatos by the bushel, 45 lbs for $6. That gives you a lot of tomatoes, generally 30ish quart jars. Yes you have to peel and cook, but its still cheaper.
When we find sales on canned items in the store, we purchase a few extra and it adds up and in the winter when you need to buy and pay for heat....
Instead of salted sand or chemicals to melt ice, I use used kitty litter (without the tootsie rolls) and stove ashes.
We do have a glass porch with lexan for the roof, hardening plants off, keeping plants longer in the fall is wonderful , also we recieve "free heat" days, spring and fall by opening a window and door, allowing the sun to warm and circulate the air.
Can't wait to see what others are doing to help keep the earth clean!
