Are Residential Windmills Cost Effective?

Wind energy is gaining in popularity as global warming becomes a bigger problem.

More people are returning to the windmill to provide power in their homes. Using residential windmills can lessen the strain on fossil fuel dependence and, in some cases, can help slash energy bills.

Benefits

Windmills appeal to so many because they are a pollution-free way to generate electricity. Windmills do not produce any toxic gasses or fumes, making it a healthier option for those living around them. While some feel windmills are eyesores, they are quiet and use natural "renewable" sources of power, so there is no worry of running out of a power.

Initial Costs

As of 2010, initial start-up costs for a larger system capable of powering an entire home can range anywhere from $8,500 to $40,000, depending upon the size of the windmill and the power of the generator. Smaller windmills producing 100 to 400 watts, or enough energy to help get through power outages, are available from $500 to $1,000. Tax credits and start-up loans make paying this initial start up cost easier.

Cost Effectiveness

Windmills can pay for themselves in anywhere from four to 12 years after the initial setup, depending upon wind conditions of the area. For the most cost effective windmills, a home should be on land that typically averages 10 mph in wind speeds, with a constant wind supply. If irregular wind is an issue, it may be more cost effective to stay on the grid instead. It is also better to have more open land in the area to avoid obstructions to the tower. Those living in urban settings should not invest in windmills because they will not function to the best of their ability in this sort of setting.
