Ensuring environmental sustainability is paramount for achieving sustainable development and leaving a habitable world for future generations. In this regard, the transition to green energy plays a critical role by reducing environmental impacts associated with fossil fuel use and promoting environmentally friendly energy sources. Technological regulations, green technological innovation, economic globalization, and human capital are pivotal factors influencing the success of the green energy transition. Technological regulations can encourage the adoption of environmentally friendly practices through the establishment and enforcement of environmental standards. Economic globalization expands international trade and investment opportunities, supporting the transition to green energy. Human capital development ensures the availability of skilled labor and can foster knowledge creation to advance green energy initiatives. This study examines the influence of human capital, green technological innovation, technological regulations, and economic globalization on the green energy transition in 19 OECD countries from 1990 to 2019. According to the results, human capital reduces the transition in Germany and increases it in Poland; green technological innovation boosts the green energy transition in Belgium; technological regulations support it in Finland, Poland, and Panel; economic globalization reduces it in Italy. OECD countries should diversify their environmental policies with technological regulations to achieve SDG7.
