Today, just as with windmills hundreds of years ago, most wind turbines are used to provide a power source for the community at large. However, rooftop wind turbines allow the user to generate electricity from his or her home. Especially if you live in a windy area and/or have concerns about supporting alternative forms of energy, rooftop wind turbines can be a great investment.
These turbines are meant to be portable, and easy to install on top of your house, garage, or atop a commercial building such as a small business. From there, they provide energy for the residents inside. Sometimes these can power the entire household, but more likely they are used in tandem with the traditional power grid to reduce use and costs.
In remote locations, the energy gathered from rooftop wind turbines can be stored in a battery for use later. Typically, though, on days the wind blows especially hard, this excess energy that is not needed immediately can be sold back to the utility company. In this way, especially if you limit your energy use, rooftop wind turbines can gradually become profitable.
