FORTES STORTI, Dienifer Regina  e  MARTINELLI JUNIOR, Orlando. PATENTES EM ENERGIAS RENOVÁVEIS: UM ESTUDO EXPLORATÓRIO A PARTIR DE INDICADORES PARA PAÍSES SELECIONADOS. Estud. econ. [online]. 2022, vol.39, n.78, pp.127-156. ISSN 2525-1295.

This article quantifies and analyzes technological efforts, specialization profiles, and technological movements in renewable energy in the twenty main energy- consuming countries, from 1992 to 2018. A database patent is used in thirteen areas of renewable energy for the construction of structural innovation indicators, of revealed technological advantage indexes and for the application of the shift-share method. The results showed that the United States was ahead of most patents areas in renewable energy, however, Japan, South Korea and China have been revealed more dynamic countries on innovative efforts. The shift-share analysis indicated that the countries’ technological efforts do not focus only on one alternative energy source, but they connect to a wider range of renewable energy technologies.
