    Unplug Microwaves When Not In Use

    An energy saving tip!
    "Cooking With Less Gas"
    Home Energy (06/01) Vol. 18, No. 3, P. 34; Mitchell-Jackson, Jennifer;
    Meier, Alan
    Cooking with microwave ovens can be far more energy efficient than cooking
    with electricity or natural gas, depending on the fluctuating price of gas.
    Microwaves are superior in efficiency when compared to electric or gas ovens
    because of smaller heat losses and no need to preheat. However, electric
    stovetops use less energy to boil water than a microwave because heat is
    applied directly to the container on the stovetop. At the same time, people
    tend to cook smaller portions in the microwave than on the stovetop, so the
    microwave can still win the efficiency race in the end. While microwaves do
    use less energy for defrosting frozen meat than they do for cooking,
    thinking ahead and putting the meat in the refrigerator the day before saves
    even more energy and is cheaper. Owners of microwaves may want to consider
    unplugging the ovens if they are only used occasionally because small
    components that are on all the time, such as a digital clock, can sometimes
    use more power over the lifespan of the product than the energy used to cook
    food. (
