Renewable Energy Transition: A Debate on Feasibility and Timing

"Researchers such as McDonald, R (2019), Stephanie J(2021) and Martinez believe that it will be difficult to replace fossil fuels with renewable energy. However, others believe that a transition to renewables could be much quicker (David Mitchell, 2022;Wilson; McMullan, 1962)." The sentence contains a grammatical error in the citation format. "David Mitchell, 2022;Wilson; McMullan, 1962" is not properly formatted. It should either be listed with consistent formatting for all authors (e.g., "David Mitchell, 2022; Wilson; McMullan, 1962" or "Mitchell, 2022; Wilson; McMullan, 1962") or separated into distinct citations (e.g., "(David Mitchell, 2022) and (Wilson; McMullan, 1962)" or "(Mitchell, 2022), (Wilson), and (McMullan, 1962)").
