The argument for investing in nuclear power highlights its significant environmental benefits, such as low greenhouse gas emissions and high reliability. However, concerns about nuclear safety, radioactive waste management, and high capital costs remain critical factors to consider. Advances in reactor technology, like small modular reactors, propose safer and more cost-effective alternatives. Additionally, integrating nuclear power with renewable sources could balance reliability and sustainability. Despite initial expenses, nuclear energy's capacity for large-scale, consistent power generation is vital for a diversified, low-carbon energy portfolio. Future investments should prioritize safety innovations and waste disposal solutions to maximize nuclear power's potential while mitigating risks. Ultimately, nuclear energy complements renewable sources as part of a comprehensive strategy to combat climate change and ensure energy security.

Investing in nuclear power presents a compelling case for sustainable and reliable energy generation, particularly amidst the urgent need to reduce greenhouse gas emissions and transition to cleaner energy sources. As a low-carbon energy option, nuclear power significantly contributes to reducing the carbon footprint associated with traditional fossil fuel-based energy sources. Unlike coal or natural gas, nuclear reactors do not emit CO2 during operational phases, making them an essential part of strategies aimed at achieving climate targets such as those outlined in the Paris Agreement (International Atomic Energy Agency [IAEA], 2020).
One of the primary advantages of nuclear energy is its reliability and capacity to produce consistent power irrespective of weather conditions, contrasting sharply with intermittent renewable sources like solar and wind (World Nuclear Association [WNA], 2022). Nuclear power plants operate continuously for long periods, often 18–24 months before refueling, thus providing a stable and dependable energy supply critical for modern economies. This stability is particularly vital as the global economy shifts toward electrification, including transportation and industrial processes.
Despite these benefits, the high capital costs and complex regulatory requirements associated with nuclear power are considerable barriers to widespread adoption. Construction costs for nuclear power plants are significantly higher than for renewable energy facilities, often exceeding several billion dollars per plant (Egenhofer & Huenteler, 2019). Safety concerns, particularly regarding potential accidents and radioactive waste management, have historically fueled public opposition and regulatory hurdles. However, technological innovations such as small modular reactors (SMRs) could mitigate some of these challenges by offering safer, scalable, and cost-efficient alternatives (World Nuclear Association, 2021).
The environmental impact of nuclear waste remains a contentious issue. Nevertheless, advancements in waste reprocessing and disposal techniques have improved the safety and sustainability of nuclear waste management (Bunn & Lubinski, 2021). Reprocessing technologies can reduce waste volumes and recover usable materials, lessening the long-term environmental risks. Moreover, ongoing research into fusion energy, although still in experimental stages, promises potentially safer and more abundant nuclear energy in the future (Krawczyk et al., 2022).
In the context of climate change mitigation, nuclear power’s low operational emissions make it a strategic option. Countries like France and South Korea have demonstrated the viability of integrating nuclear power into their energy mix, achieving high shares of electricity generation from reactors while maintaining low greenhouse emissions (OECD Nuclear Energy Agency [NEA], 2020). Diversifying energy sources to include nuclear alongside renewables—such as wind, solar, and hydropower—can ensure energy security, reduce reliance on fossil fuels, and stabilize electricity prices during renewable supply fluctuations (International Energy Agency [IEA], 2021).
In conclusion, while nuclear power entails significant financial and safety challenges, its advantages in providing reliable, low-carbon electricity are undeniable. Future investments should prioritize technological innovations that enhance safety and waste management, as well as supportive policies that facilitate nuclear development. As part of an integrated energy strategy, nuclear energy can play a pivotal role in achieving a sustainable, resilient, and low-emission global energy system.
