No. While leasing land to wind developers is still the most common way for landowners to get involved with wind energy, more and more farmers, landowners, schools, municipal utilities, and rural communities are developing projects and owning the turbines themselves.
These projects keep significantly more of the economic benefits of wind development in the local community. However, developing and owning a project yourself involves quite a bit more time and research, as well as financial risk. You have to balance risk and reward.
