Today the global energy industry is undergoing major changes shifting towards the green growth and circular economy solutions. The paper offers the outcomes of the foresight study of the Russian renewable energy sector and focuses on three areas: converting solar energy into electricity; converting wind energy into electricity; and converting biomass into thermal energy and electricity. The goal of the study was to foresee and agree on the visionary future for the nascent renewable energy sector in the country, as well as to provide the scientifically justified grounds for government and corporate decision-makers. The research is based on a mixture of methods: bibliometric analysis and text mining, literature review, expert surveys and interviews, workshops, STEEPV analysis of trends, scenario analysis, and applied policy analysis. As a result of the study, major trends and uncertainties that may affect the Russian and global renewable energy sector in the next 15-20 years were identified. Other results include the scenarios for Russia's renewable energy sector that are proposed together with recommendations for the Russian companies and public authorities. The study's policy and market implications go beyond Russia: the outcomes may be useful for similar studies, early stage renewable energy policy planning and investment decision.
