Now is a good time to remove, clean and store your in-window air conditioners. This protects your air conditioner from the harsh winter elements so when it's time to re-install it, it will actually work; plus, it helps remove small cracks and crevices from your open window when you're trying to keep your home warm. If you can't remove the unit, wrap it in plastic sheeting with insulation inside, and use duct tape to secure it shut.

If you love burning candles at home, it's common knowledge that paraffin wax alternatives like soy wax will burn cleaner and release fewer pollutants into the air. But when shopping for soy wax candles, buyer beware. If a candle is simply marked "soy wax" or "soy blend," there's no guarantee that it is 100 percent soy. In fact, only 51 percent of the candle needs to be soy wax to be called a soy candle. The other 49 percent can be any wax, including paraffin. Look for candles marked 100 percent soy wax to be absolutely sure.

Are you an aggressive driver? If so, you might be wasting tons of gas and money. When you drive at speeds at or below 55 miles per hour, your car is working at maximum fuel efficiency. Go any faster, and for every 5 miles in speed above 55, you decrease your fuel efficiency by 10 percent. So if you're sailing at 75 miles per hour, you've wasted 40 percent fuel efficiency on your car. Stay safe, save fuel and drive at reasonable speeds whenever possible.
