Renewable energy appears to be the most optimal alternative to fossil fuel and the widely accepted pathway towards the mitigation of climate change. However, the costs of adopting renewable energy are high, and it appears the wealth of nations, the stages of economic development and growth and institutional willingness and quality are important in winning this global challenge. However, there is limited information on the interplay of all the factors that are perceived as critical in moving the world towards the use of renewable energy sources to meet most of the domestic and industrial energy needs. This study investigates the inter-temporal causal relationship between institutions, renewable energy, carbon emissions and economic growth for 45 sub-Saharan Africa countries using annual data for the period 1960–2017. We used the generalised method of moment panel vector autoregression (GMM-PVAR) technique to explore the linkages. From a general perspective, the results reveal that no causal relationship exists between institutions and economic growth, but a bidirectional causality exists between economic growth and renewable energy. Our results indicate that economic growth causes carbon emissions, and institutions are more likely to respond to carbon emissions and renewable energy but prompts no causality exists between carbon emissions and renewable energy. Interestingly, these results differ between countries with different institutional origin. The policy implications are discussed.

撒哈拉以南非洲的可再生能源、二氧化碳排放和经济增长:制度质量重要吗?

可再生能源似乎是化石燃料的最佳替代品,也是缓解气候变化的广泛接受的途径。然而,采用可再生能源的成本很高,看来国家的财富、经济发展和增长的阶段以及制度意愿和质量对于赢得这一全球挑战很重要。然而,关于所有被认为是推动世界使用可再生能源以满足大部分家庭和工业能源需求的关键因素之间相互作用的信息有限。本研究使用 1960 年至 2017 年期间的年度数据,调查了 45 个撒哈拉以南非洲国家的制度、可再生能源、碳排放和经济增长之间的跨期因果关系。我们使用矩面板向量自回归 (GMM-PVAR) 技术的广义方法来探索联系。从总体上看,研究结果表明制度与经济增长之间不存在因果关系,但经济增长与可再生能源之间存在双向因果关系。我们的研究结果表明,经济增长导致碳排放,机构更有可能对碳排放和可再生能源做出反应,但提示碳排放与可再生能源之间不存在因果关系。有趣的是,这些结果在具有不同制度起源的国家之间有所不同。讨论了政策含义。结果表明,制度与经济增长之间不存在因果关系,但经济增长与可再生能源之间存在双向因果关系。我们的研究结果表明,经济增长导致碳排放,机构更有可能对碳排放和可再生能源做出反应,但提示碳排放与可再生能源之间不存在因果关系。有趣的是,这些结果在具有不同制度起源的国家之间有所不同。讨论了政策含义。结果表明,制度与经济增长之间不存在因果关系,但经济增长与可再生能源之间存在双向因果关系。我们的研究结果表明,经济增长导致碳排放,机构更有可能对碳排放和可再生能源做出反应,但提示碳排放与可再生能源之间不存在因果关系。有趣的是,这些结果在具有不同制度起源的国家之间有所不同。讨论了政策含义。机构更有可能对碳排放和可再生能源做出反应,但提示碳排放和可再生能源之间不存在因果关系。有趣的是,这些结果在具有不同制度起源的国家之间有所不同。讨论了政策含义。机构更有可能对碳排放和可再生能源做出反应,但提示碳排放和可再生能源之间不存在因果关系。有趣的是,这些结果在具有不同制度起源的国家之间有所不同。讨论了政策含义。
