An electric energy generation system may include a plurality of windmills, a windmill support system, an electric generator, and a coupling system. The windmills may each be configured to transform wind energy into rotational energy. The windmill support system may support the windmills in positions that are spaced apart from one another. The electric generator may be configured to transform rotational energy into electric energy. The coupling system may be configured to couple the rotational energy generated by each of the windmills to the electric generator in a manner that permits the windmills to rotate at different speeds during operation of the electric energy generation system. Other configurations are also disclosed.
