Buy a good used bicycle at a thrift shop or garage sale. Find a nice usable basket for it. Ride it to the grocery store, farmer’s market or to do short limited errands. This will increase your cardiovascular exercise and save lots on gas.
If you do drive group the stops by starting at the furthest and working back. That way if it takes two times you will have eliminated the farthest locations already.
I gauge my acceleration speed on the timing of the next light. So many times I arrive just as the light turns green, which allows me to keep my speed level instead of racing to wait at the next light. That burns gas and shortens the life of your brakes.
I insist on a large freezer. I stockpile bulk or sale items like bread, milk, pasta, rice, flour, meat, etc. I make my own spaghetti sauce, gravy, enchiladas sauce. I freeze large quantities of sauces, meals, and freeze them in meal sized portions. This save numerous trips to the store as well as stops impulse purchases. With a good meal plan you are less likely to eat out and can cook numerous meals at once saving time, cleanup and energy prices.
One of fav things to do is to find whole chickens on sale. Clean the inside and pull off the outer skin and the excess fat. Spice and add onion, and garlic. I Roast 2 at a time in my roaster oven at 375 for around 2 hours. The bottom of the roaster has about 2 cups of water in the bottom. The juices from the chicken makes into broth while the chicken is cooking. I let the chicken cool in the fridge and pour the broth into a large bowl to chill. After the chicken is cooled I pull the meat off the bones and pack into a one quart freezer bag. The bones are then thrown into a large pot cover with water, spices, 1 cup diced onion, several cloves of pressed garlic. Cook for 30-40 minutes. Toss out bones and chill. After the fat has risen to the top, discard the fat pour into freezer bags and freeze. Label with content and date. The broth can be used for gravy, soups, rice pilaf, etc. This makes an excellent low sodium, low fat chicken broth.
Do not own a cloths dryer here. 100% air dry. Saves a lot of $.
Percolate my own coffee on the gas stove.
Haven’t gone out to eat in ages. My gas usage is barely anything.
