The United States continues to progress in clean energy innovation — even after announcing its intent to pull out of the Paris Agreement. The U.S. ranks fourth among all countries (behind Norway, Finland and Japan) in terms of its contributions to the global clean energy innovation system on a per-capita GDP basis according to the ITIF Global Energy Innovation Index. Still, “without more and faster clean energy innovation, it will be virtually impossible to meet global climate emission goals,” write the index’s authors.
Among other trends, the index considers the growth of high-impact startups, which can help incubate emerging clean technologies. On that front, “the global system is dependent on a few countries, led by the United States in absolute terms, to perform this function.” Still, a lack of public funding for demonstration of capital-intensive technologies “appears to be a major weakness in the global energy innovation system.”
