The fourth industrial revolution has transformed into a rapid development process centered on renewable energy and technological innovation (TI), which provides feasible paths for mitigating carbon dioxide (CO₂) emissions. Therefore, this paper employs the Wavelet-Based quantile on quantile approach to investigate the capacity of renewable energy consumption (REC) and TI of promoting net-zero emissions in the U.S., respectively. We overall find the significant emissions-mitigating effect of REC and suggest that renewable energy serves as an effective driver to contain environmental degradation; this conclusion is endorsed by the interaction mechanism between environment and energy. However, TI captures less influence on emissions than REC, revealing a weak role in promoting emissions reduction. Therefore, industries should boost environmental awareness and incentives for TI related to REC to …
