The World Bank’s Strategic Shift Toward Nuclear and Mixed-Energy Pathways in the Global South: Rethinking Energy Futures

In a significant policy shift, the World Bank has formally ended its long-standing moratorium on nuclear energy funding in developing countries. This move reflects growing global energy demands, especially across the Global South, and marks a decisive pivot in development finance strategy. As debates over energy justice, climate responsibility, and technological pragmatism intensify, the Bank’s recalibration—anchored in its "all-of-the-above" energy philosophy—suggests a more flexible and politically navigated approach to sustainable energy transition. This article analyzes the nuances of this strategic realignment within the broader discourses of energy diplomacy, global development, and climate politics.

A Strategic Realignment in Global Energy Financing

The World Bank’s recent announcement to lift its 2013 ban on financing nuclear energy projects in developing countries signals a decisive shift in its institutional approach to energy and development. This policy transition, articulated by World Bank President Ajay Banga, emerges amidst a global reevaluation of energy imperatives, driven by intensifying demands for electrification in the Global South and the urgent need to decarbonize energy systems. Banga, in his internal memo to staff, noted that this transformation follows what he described as a “constructive discussion” with the Bank’s board, underlining a pragmatic turn in energy diplomacy that embraces a diversified portfolio of energy technologies.

The World Bank’s reversal on nuclear energy comes at a time when electricity demand in developing economies is forecast to more than double by 2035. As Banga highlighted, meeting this demand will require more than doubling the current annual investment of $280 billion in energy infrastructure—including generation, grid expansion, and storage. This recalibrated energy strategy marks a break from past exclusions and aligns the Bank’s operations more closely with the evolving realities of energy development and geopolitics.

Revisiting the Exclusion of Nuclear and Gas: Between Realism and Reform

Since 2013, the World Bank maintained a de facto exclusion of nuclear energy projects from its financing framework, echoing global concerns about proliferation, safety, and environmental risks. This decision was extended in 2017 to include a phase-out of upstream oil and gas financing, effective from 2019, albeit with exceptions for the poorest nations. However, the reconsideration of these exclusions reflects both political and technological shifts in global energy strategy.

While consensus around the inclusion of nuclear energy appeared to coalesce easily among board members, debates regarding natural gas remained unresolved. Countries like Germany, France, and the United Kingdom reportedly expressed reluctance to fully endorse an expanded gas financing framework. This hesitation highlights the persistent tension between climate commitments and the perceived developmental utility of transitional fossil fuels—particularly in the Global South, where infrastructural inertia and affordability concerns remain paramount.

Energy policy scholars such as Sovacool and Dworkin (2014) have emphasized that sustainable transitions require flexibility rather than ideological rigidity. The World Bank’s evolving posture appears to echo this argument, shifting toward what Banga termed an “all-of-the-above” strategy—a pluralistic framework designed to adapt to the contextual needs of individual countries while maintaining macro-level development and climate goals.

The Role of the United States and Geopolitical Energy Realism

The strategic momentum behind the World Bank’s decision has been reinforced by the geopolitical priorities of major shareholders, particularly the United States. As the Bank’s largest stakeholder—holding over 15% of shares—the U.S. under the Trump administration actively lobbied for the reintegration of nuclear and natural gas into the Bank’s development agenda. At the April IMF-World Bank Spring Meetings, then-U.S. Treasury Secretary Scott Bessent argued that the Bank should focus on “dependable technologies,” expressing skepticism toward what he termed “distortionary climate finance targets.”

This stance is consistent with broader American energy diplomacy under Trump, which emphasized energy independence, technological pragmatism, and market efficiency. While controversial, the U.S. argument resonated with several development experts who contend that access to reliable and affordable energy remains a precondition for economic growth in low-income countries. As Goldman (2011) observed, institutions like the World Bank often act as battlegrounds where competing visions of development, sovereignty, and sustainability collide.

Thus, the lifting of the nuclear ban represents not just a technical decision, but a geopolitical realignment, reflecting a new balance of priorities among the Bank’s governing members. It also illustrates the persistent role of powerful states in shaping the contours of multilateral development agendas, despite growing calls for democratized global governance.

Nuclear Energy and Technological Optimism in the Global South

Currently, 28 countries operate commercial nuclear reactors, with at least 10 additional states preparing to deploy nuclear power infrastructure by 2030. According to data from the Energy for Growth Hub and Third Way, a further 10 countries are also exploring the feasibility of such transitions. The World Bank’s decision comes at a time when nuclear technology—particularly small modular reactors (SMRs)—is being reimagined as a scalable, safe, and low-carbon solution for electricity access.

Recognizing the risks associated with nuclear proliferation and safety, Banga noted that the World Bank Group will work closely with the International Atomic Energy Agency (IAEA) to enhance its capacity for advising on nuclear safeguards, regulation, and security frameworks. This partnership aims to reinforce institutional mechanisms that can mitigate the dangers historically associated with nuclear power, thereby legitimizing it as a responsible development tool.

As Hecht (2012) argued in Being Nuclear, the governance of nuclear power in the Global South often intersects with postcolonial anxieties and technopolitical legitimacy. In this light, the World Bank’s support for nuclear development can be interpreted not just as a policy shift but also as a symbolic endorsement of technological sovereignty for countries historically marginalized from high-tech energy systems.

Balancing Innovation and Climate Equity

The World Bank’s revised strategy also recognizes that the pursuit of net-zero emissions does not equate to a fossil-free future. Citing global figures, Banga emphasized that approximately 20% of future energy generation is expected to come from fossil fuels, underscoring the need for transitional sources like natural gas, particularly where it represents the least-cost and least-risk option.

Barbados Prime Minister Mia Mottley, a vocal advocate for climate justice, has argued that natural gas should be viewed as a “clean fuel” within the broader matrix of net-zero strategies. Her perspective aligns with the principle of common but differentiated responsibilities enshrined in international climate agreements, emphasizing that developing nations must be granted greater policy space in charting their energy futures.

Nonetheless, environmental advocates continue to express concern that the renewed emphasis on nuclear and gas may divert crucial financing away from solar, wind, hydro, and other renewables that offer long-term sustainability and resilience. Climate justice scholars such as Newell and Mulvaney (2013) have warned of the “false solutions” that can arise when transitional technologies are privileged over transformative approaches.

The Bank’s approach attempts to mediate this tension by allowing countries to determine their own optimal energy mix, while maintaining support for renewable integration, carbon capture, and grid modernization. Banga also reiterated the Bank’s commitment to advising on coal plant retirement and ensuring that carbon capture technologies are not deployed for enhanced oil recovery, which he argued can typically secure private sector funding without public support.

Toward a Pluralist Energy Future
The World Bank’s policy transformation represents a significant milestone in the evolving discourse of global energy governance. By lifting its nuclear financing ban and signaling a more inclusive attitude toward transitional fuels, the institution is repositioning itself as a pragmatic broker in a rapidly changing energy landscape.

This move is not without controversy. As development finance becomes increasingly entangled with geopolitics, climate urgency, and technological nationalism, the challenge for institutions like the World Bank will be to sustain legitimacy while balancing competing imperatives. The tension between environmental sustainability and energy justice remains unresolved, but the Bank’s embrace of technological pluralism may open new spaces for negotiated development.

Ultimately, as Banga suggested, electricity must be understood not only as a technical necessity but as a driver of economic transformation. The future of energy diplomacy, therefore, will hinge on the ability of global institutions to foster innovation, adaptability, and equity—without losing sight of the climate thresholds that define our planetary limits.
