In recent years, the wind industry has undergone considerable development worldwide, thanks mainly to state support for renewable energy embodied in various standards and initiatives. However, the situation differs significantly among the main world producers of electricity from wind power, and in some, we can find incomplete energy policies and regulatory frameworks, which have led to very different economic and social outcomes. In this paper, we present a comparative study of wind policies (based on a multidisciplinary approach) in the leading countries of Europe, Asia and America, in order to establish a comprehensive framework for the sector's future.
