Winds of Change examines the global development of the wind energy industry from a political, social movements-based perspective. It argues the wind energy industry developed successfully in certain regions and countries in large part because the environmental movement influenced its growth. Vasi then defines and analyses the three main pathways through which the environmental movement has contributed to industry growth: it has influenced the adoption andimplementation of renewable energy policies, it has created consumer demand for clean energy, and it has changed the institutional logics of the energy sector. The book uses quantitative analysis to present the big picture of the global development of the wind energy industry, then draws on qualitative analysesto understand why countries such as Germany, Denmark, or Spain are world leaders in wind energy, while other countries such as the United States, United Kingdom, or Canada have a somewhat underdeveloped wind power industry. It also analyzes how the environmental movement contributed to the recent growth of the market for renewable energy certificates in the United States. The book also examines the remarkable transformation of the electricity sector in different countries, showing howenvironmentalists in Germany, Denmark, United States and United Kingdom contributed to wind turbine manufacturing by becoming entrepreneurs, innovators, and/or advocates, and, furthermore, how environmental groups and activists formed new companies that specialize in wind-farm development and operation, andpressured utility companies to invest in renewable energy by using tactics such as protests, lawsuits, and lobbying for stricter regulation. In conclusion, Vasi presents the main implications for future studies on industry development and social movement outcomes, as well as for the future growth of the renewable energy sector.
