The impact of government-funded renewable energy R&D on its consumption

With the increasing urgency to shift away from fossil fuels, many governments are boosting their funding for renewable energy research and development (R&D). The fundamental premise behind these efforts is that government-funded renewable energy R&D contributes to increased consumption of renewable energy. This paper examines this premise employing panel data from 26 countries between 1974 and 2022. Based on panel cointegration methods and panel causality tests, this study finds robust evidence of a statistically significant positive long-term relationship between government-funded renewable energy R&D and renewable energy consumption. It also identifies unidirectional causality running from the former to the latter.
