Several major economies are significantly increasing their commitments to nuclear power as a primary component of their decarbonization strategies. Following the landmark agreement at COP28 to triple global nuclear capacity by 2050, countries including France, the United States, and China have announced new reactor projects and funding initiatives. Proponents argue that nuclear energy provides a stable, high-output baseload power source that complements intermittent renewables like wind and solar. However, the expansion faces scrutiny from environmental groups concerned about long-term radioactive waste management and the high capital costs associated with new builds. While some nations are fast-tracking Small Modular Reactors (SMRs) to reduce lead times, analysts suggest that regulatory hurdles and supply chain constraints remain significant challenges to meeting the ambitious mid-century goals.
