Cooking advice
Buy Local Food : Strawberries, blueberries and many other kinds of fruit often are available from farms that allow you to do the harvesting (or not, if you prefer to pay for the cost of picking). Many fruits are easy to freeze, and apples will keep all winter in a cool corner of the garage.
Oven Tips : If you don't have one, consider buying a self-cleaning oven. They use less energy for normal cooking because of higher insulation levels. They also save on your rubber glove and cleanser purchases! However, if you use the self-cleaning feature more than once a month, you'll end up using more energy than you saved. When you clean the oven, do it right after cooking to take advantage of residual heat.
