Promoting the development of renewable energy sources is crucial for sustainability. This paper explores the impact of energy security risks and economic complexity on expanding renewable energy sources, accounting for trade openness and economic growth for the top 23 energy consumers. The period of observations spans from 1997 to 2017. The study was conducted using panel quantile regression methods with fixed effects. The empirical outcomes indicate that economic complexity has a significant negative effect on renewable energy at low quantiles but a positive effect at medium to high quantiles. Furthermore, economic complexity has a greater impact on middle-income countries than on high-income countries. Energy security risks positively and significantly impact renewable energy development. However, for middle-income countries, the impact of energy security risks on renewable energy is unstable. The impact is at its peak between the 60th and 70th quantiles and then declines to its lowest level between the 80th and 90th quantiles. The robustness tests confirm the earlier findings. Based on empirical outcomes, policy prescriptions are suggested to address renewable energy deployment against the backdrop of sustainable development concerns. The policy implications suggest that the government should actively promote trade openness and increase economic complexity. Greater energy security risk index shocks increase the use of renewable energy. • Studies roles of economic complexity and energy security on renewable energy. • On 23 top energy users for 1990–2017. • Advanced quantile regression technique adopted. • Scale effect and composition effect of economic complexity on divergence of impact. • Empirical outcomes have directions on policy for SDG.

The G7 countries consist of some of the world's most economically developed nations. However, alongside such robust economic growth performances, the environmental qualities in these countries have simultaneously aggravated to raise deep concerns among the stakeholders. Hence, this study is designed to empirically examine the environmental effects of nuclear and renewable energy consumption, economic complexity, and economic growth in the context of the G7 countries for the period between 1995 and 2016. To ensure novelty, this study considers carbon footprints along with carbon dioxide emissions to measure environmental quality in the context of the G7 nations. The results reveal that although nuclear energy consumption is effective in mitigating carbon dioxide emissions and carbon footprints in the long run, renewable energy consumption degrades the environment in the G7 countries. Besides, the results also suggest that the G7 countries can transform their production processes in an environmentally friendly manner provided they can undergo a clean transition in energy use. Finally, economic growth is evidenced to be detrimental for the environment since higher economic growth levels are seen to boost both carbon dioxide emission and carbon footprint levels. Therefore, in line with the findings, this study recommends the G7 countries to significantly enhance their nuclear and renewable energy consumption levels, increase their economic complexity indices, and integrate environmental welfare policies within their economic growth strategies. • Determinants of CO 2 emissions and carbon footprints are evaluated in G7 countries. • Renewable energy use boosts CO 2 emissions and carbon footprints. • Nuclear energy use curbs CO 2 emissions and carbon footprints. • Economic complexity reduces CO 2 emissions and carbon footprints. • Economic growth stimulates CO 2 emissions and carbon footprints.
