The global wind industry has faced a series of policy changes in recent years as markets mature and various countries position to take advantage of wind energy?s competitiveness against fossil-based power plants. Within this changing environment, growth in some of the countries with the most installed wind power capacity has stalled while others are warming up for further expansion. In this Global Wind Energy Policy Update, Navigant Research analyzes the policies selected by each country to evaluate which markets are most likely to attract investors and experience further wind power capacity expansion. Until recently, most countries have preferred wind-related policy mechanisms that were transparent for the developer in order to encourage investment and spur development. As the cost of wind energy has plunged in recent years thanks to technology improvements and efficiencies of scale, many governments have begun exploring or implementing market-oriented policy mechanisms that decrease costs for supporting governments, ratepayers, and other stakeholders. While the mix of countries seeking to grow wind capacity continues to expand due to lower but stable growth rates today, only one country is ranked by Navigant Research as Booming (China) and three others are Outperformers (the United States, India, and?barely reaching the category?Germany). This Navigant Research report examines the strengths and weaknesses of the wind policy regimes across 42 countries based on an analysis of key policy, economic, and structural factors. Countries are rated on four criteria: policy stability, past performance, sector potential, and economic forecast. Each country covered in this report is ranked across four categories of attractiveness to investors: Booming, Outperformers, Growing, or Stalled.
