Abstract

Wind energy stands as a pivotal renewable energy source, along with continuous technological advancements over the years. However, there is a lack of research on how to foster innovation relate wind components. This study develops patent search strategies and establish patent databases in wind energy and its components, alongside a manually collected policy database, across 112 countries from 1980 to 2020. The findings indicate a notable upturn in wind policies and patents from around 1995, peaking in 2010. The econometric results reveal both fiscal instruments and voluntary programs significantly foster innovation, particularly fiscal instruments in non-Organization for Economic Co-operation and Development (non-OECD) countries. However, quotas, along with information and education, exhibit a detrimental effect overall. Moreover, contrary to common perception, the results show that regulation and legislation demonstrate significant potential in driving innovation in core and exclusive wind components, such as blades and control systems. Counterfactual analysis further reveals fiscal instruments contributed 123.7 % growth in wind patents, while voluntary programs contributed 3.1 %. Additionally, regulation and legislation contributed 77.9 % and 237.8 % growth in blade and control systems, respectively. The findings underscore the importance of understanding the impact of diverse policies on various types of innovations to foster advancements in wind technology.
