# Former US Energy Secretary on the coming decade's energy race Nuclear power, grid investment and public-private models will shape the future - **Source:** [McKinsey Insights](https://www.mckinsey.com/insights) - **Published:** 2026-09-22 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/239a7d1f-278e-4ba4-8c9d-f8625fc07494 ## The electron race Former US Energy Secretary Ernest Moniz frames the next decade as a global competition for electrons, where nations will vie for energy dominance. This race encompasses electricity generation, transmission infrastructure and storage solutions. The physicist-turned-policymaker emphasizes that leadership in this arena will determine economic competitiveness and geopolitical influence through the 2030s. ## Nuclear's critical role Moniz identifies nuclear power as an indispensable component of the future energy mix, despite public skepticism. He points to advanced reactor designs and small modular reactors (SMRs) as game-changers that could make nuclear more scalable and cost-effective. The technology offers reliable baseload power without carbon emissions, addressing both climate and energy security concerns. ## Grid modernization imperative The interview highlights how aging electricity infrastructure requires massive investment to handle renewable integration and increasing demand. Moniz stresses that transmission system upgrades are equally important as generation capacity additions. Smart grid technologies and expanded interconnections will be needed to optimize electron flows across regions. ## Public-private innovation Moniz advocates for new partnership models between government and industry to accelerate energy innovation. He draws from his experience establishing the Energy Futures Initiative, demonstrating how collaborative R&D can bridge the commercialization gap for emerging technologies. These partnerships must balance risk-sharing with clear accountability metrics. ## Policy continuity challenges The discussion reveals how political cycles often disrupt long-term energy strategies that require decades of consistent implementation. Moniz notes that public-private models can provide stability against shifting political winds. He cites examples where bipartisan support has sustained critical energy programs across administrations. ## Workforce transition The energy transition will require retraining millions of workers as industries evolve. Moniz emphasizes creating pathways for fossil fuel workers to transition into clean energy jobs. This includes targeted education programs and regional economic development strategies to ensure no communities are left behind in the shift. ## Global dimension Moniz underscores how the energy race extends beyond national borders, requiring international cooperation even amid competition. He points to areas like nuclear nonproliferation and grid interconnection standards where coordination is essential. Emerging economies present both challenges and opportunities for clean energy deployment. ## Strategic priorities The interview concludes with Moniz outlining three critical focus areas: accelerating nuclear innovation, modernizing grid infrastructure, and fostering effective public-private collaboration. He stresses that these elements must progress simultaneously to meet both climate goals and energy security needs in the coming decade. ## Sources covering this story - https://www.mckinsey.com/industries/electric-power-and-natural-gas/our-insights/powering-through-uncertainty-a-talk-with-former-us-energy-secretary-ernest-moniz — --- _Summary written by Brifing from the original reporting.
