Waiting until the 2040s for new built nuclear power or you know, just investing in renewables and storage?
You seem stuck in some imaginary perfect world, always looking back rather than daring to look forward.
Even the French are wholly unable to build new nuclear power in 2026 as evidenced by their zero commercial reactors under construction and the state of the EPR2 program. The French fleet will shrink due to all plants hitting EOL without replacements in sight.
Looking at cumulative emissions any investment in renewables, even if they are imperfect, extends our timeline for reaching perfect by decades. Due to their deployment speed and how effective they are at decarbonization per dollar spent.
