Vertical Axis Wind Turbine Evaluation and Design

strategy is to use wind turbines that generate electricity from wind. 2.1 Wind Intro Wind is generated from solar energy unevenly heating the earth. This uneven heating creates pressure changes in the atmosphere, generating wind. This wind can then be harnessed by a wind turbine. As the wind pushes the blades of a turbine, a generator
