I think 'individually and jointly owned wind farms' is neater and covers the different types of joint ownerships.

In Denmark, for example, approximately 80% of all wind turbines are either individually or cooperatively owned, and a similar pattern holds in Germany, the world leader in installed wind capacity. Sweden also has a strong wind cooperative base, and the UK has recently made forays into community wind ownership.

2. Group Ownership
Investing with others gives you the opportunity to reap greater rewards than leasing your land with less risk than owning the turbines by yourself. As a joint investor, you would be a part owner of a wind farm. The entire investment group would be responsible for developing and managing the wind farm, which cuts out the third party developer. There are many forms of joint ownership, from two partners to corporations with large numbers of shareholders. If you decide to build a partnership or pursue a joint venture to retain equity in wind turbines on your land, you can choose from several options:

* Pass-Through Entities

* Consumer Cooperative

* Limited Liability Company (LLC)

* Partnership

3. Individual Ownership
If you choose to own a turbine yourself, you assume all responsibility for the work and all the risks. You also receive all the profits. Wind turbines vary greatly in physical size, price, and the amount of electricity they generate. A large scale turbine typically costs more than $1,000,000 while small turbines can cost less than $50,000.

Community Wind in Europe

European community-owned wind projects have been around since the 1970s. In Denmark, the birthplace of community wind, about 80 percent of installed wind capacity is individually or co-operatively owned; in Germany it’s about 51 percent. Sweden also has co-operative wind, and the community wind market in the UK is growing.

Community, Co-operative and Municipal

There are three main business models for community wind projects. In the wind energy co-operative model, developed in Denmark, wind turbines are jointly owned. For example, in Copenhagen’s Middelgrunden Wind Turbine Cooperative, shareholders buy shares corresponding to 1/40,500 of the partnership each. Of the 20 turbines in the harbour, local utility Copenhagen Energy owns the 10 northern turbines and the co-operative owns turbines 11-20. U.S. observers have cited this public/private partnership model as a potentially interesting way to move projects forward.

In another model, some wind turbines are municipally owned and operated, sited on town land, and tax exempt. As an example, the Hull Wind One project in Boston, Massachusetts, which boasts a 660-kW Vestas turbine, ‘zeroed out’ the town’s street lighting bill and generated 1,597,367 KWh in its first year. Of the town’s residents, 95 percent support the project.
