Improvements to wind farms and wind generators for harnessing wind energy or generating electricity from wind. Secondary wind turbines are provided at particular locations within a wind farm to generate additional electricity, in some embodiments, using a common electrical power collection system. Enclosures or venturis may surround wind turbines to facilitate mounting close to the ground. Venturis may accelerate wind speed through the turbine and may have a particular shape, may be made of particular materials arranged in particular ways, or both. In different embodiments, wind turbines may be axial-flow horizontal-axis turbines, or may be Savonius turbines, as examples. And in some embodiments, wind turbines may be combined with other power production equipment, such as solar power equipment, for instance.
