Özet
The study examines how critical factors affect the energy transition in the countries that invest the most in energy related R&D (namely, the USA, France, Japan, & Germany). The study empirically analyzes the impact of energy-related R&D investments, income (GDP), primary energy consumption (PEC), and human capital (HUC) by applying a novel super learner (SL) algorithm for the period from 2000/Q1 to 2022/Q4. The outcomes demonstrate that (i) the SL algorithm performs better than all others; (ii) nuclear and renewable energy R&D investments support the energy transition in the USA, while energy efficiency R&D investments are helpful for France and Germany, and no R&D types are beneficial for Japan; (iii) GDP and HUC support the energy transition in almost all countries; (iv) PEC supports the energy transition in France and Japan. Hence, on energy transition, the study proves the dominant effect of renewable energy R&D in the USA, HUC in France, energy efficiency R&D in Japan, and, energy efficiency and nuclear energy R&D in Germany, while other factors have less influence.
