A good way to save energy in your home is frank and simple: put on a sweater. That way you do not have to turn the heat up to stay warm. So, why not apply this practice elsewhere? For example, in your car! My advice is this: if it's cold out, put gloves on! My hands tend to get the coldest when I drive because they're exposed directly to air and have to hold the freezing steering wheel! When I wear gloves I am exponentially warmer and less inclined to blast the heat. If I don't have to blast the heat then I save gas! So, save gas, wear gloves!
