With the price of energy having risen so drastically over the past decade or less, many people are looking for ways to cut back on energy usage in their homes or when using vehicles. There are some simple opportunities to do this if you take a little time and think about it. One tip is to close off the vents in any room in your home that is not used much. Extra bedrooms or guest rooms are good candidates for this. Also, close the door leading into those rooms as well. It is a wise idea to have an energy audit performed at your residence and then act upon the suggestions that are made. Make sure the air filters for your furnace and air conditioner are clean. Lastly, have a programmable thermostat installed in your home. This will save you a considerable amount of money over time and prevent you from wasting energy.
