We analyze inventions in green energy technologies over the period 2005-2017. We use a novel dataset, making use of the IPC Green Inventory of the World Intellectual Property Organization (WIPO) to analyze four broad categories of green energy technologies including alternative energy production technologies, energy conservation technologies, and green transportation. We use these data to look at how patent families and PCT international patent applications have evolved in this field in recent years. We find that energy innovation-related patenting has first expanded exponentially up until 2013, both in terms of the total number of patent families and PCT international patent applications in green energy technologies. Yet this period of accelerated growth in the number of published green energy patents has been followed by a period of deceleration—even a slow decline. Although most green energy technologies have seen a downward trend in the annual number of patents published since 2012, the decline has been most pronounced in nuclear power generation technologies and alternative energy production technologies. The latter notably include renewable energy technologies, such as solar and wind energy, and fuel cells. In contrast, patents in energy conservation technologies and green transportation technologies have continued to grow, but at a slower pace.

An edited volume on factors determining success or failure of energy technology innovation, for researchers and policy makers.

Measuring innovation in education and understanding how it works is essential to improve the quality of the education sector. Monitoring systematically how pedagogical practices evolve would considerably increase the international education knowledge base. We need to examine whether, and how ...

Innovation in energy technologies : hearing before the Committee on Energy and Natural Resources, United States Senate, One Hundred Ninth Congress, first session, to consider our national capacity for producing technological innovation and the importance of this innovation to our global economic competitiveness, and to receive testimony describing the results of a recently released National

Accelerating energy innovation could be an important part of an effective response to the threat of climate change. Written by a stellar group of experts in the field, this book complements existing research on the subject with an exploration of the role that public and private policy have played in enabling—and sustaining—swift innovation in a variety of industries, from agriculture and the life sciences to information technology. Chapters highlight the factors that have determined the impact of past policies, and suggest that effectively managed federal funding, strategies to increase customer demand, and the enabling of aggressive competition from new firms are important ingredients for policies that affect innovative activity.

Measuring Innovation is a major step towards evidence-based innovation policy making. It complements traditional “positioning”-type indicators with ones that show how innovation is, or could be, linked to policy.
