There are many benefits to using wind turbines for the home. Since the wind is free, you only have to pay for the initial installation and purchase of the turbine. Over time your electricity costs will be greatly reduced.
Since wind energy doesn't release any harmful carbon dioxide or other pollutants into the environment, it is a great sustainable and green use of energy. Also, you can store any excess electricity in batteries for later use when there isn't any wind.
The cost of system is going to depend on the size and how the unit is mounted to your home. Maintenance costs are going to be relatively low, but this would also depend on the size of the turbine being used. If you are using the turbine as an off-grid system, you will need to replace the batteries every six to ten years.
There are two types of wind turbines for the home; one is pole mounted and the other can be mounted on the roof or side of a building.
