I save power by using a small fan forced bench top cooker instead of the big oven. I can cook a roast meal for 4 much more economically by not heating up that MASSIVE oven most of us have in our kitchens. The small bench top oven heats faster using less power too. Slow cookers also are a great way to cook a lot of food at once inexpensively.
