The world’s economy, environment, and security all hinge on reliable access to energy. The question of how to meet the world’s power needs, while ensuring that energy is both clean and affordable, is often referred to as the energy trilemma.
To stay on track for maintaining global warming under 1.5°C, the world must deploy more than 1,000 GW of clean energy capacity every year.
But as energy consumption grows and climate change advances, the trilemma’s three priorities are no longer enough. Rising global demand, accelerating climate impacts, and geopolitical pressures have added a new constraint, time. This creates an energy quadrilemma, one in which we must quickly and simultaneously address multiple overlapping, and sometimes conflicting, needs. The theme ran through two dedicated sessions at FII PRIORITY Europe in Rome, where speakers described a transition now shaped as much by speed, geopolitics, and industrial strategy as by technology or cost. Progress is being made, but it’s slow.
The world needs energy security through reliable, resilient supply; sustainability through rapid decarbonization; and equity via affordable, universal access. Achieving all three requires investment across the full energy landscape, renewables, transmission networks, storage, and flexible generation, including fossil fuels during the transition. Increasingly, though, the binding constraint is pace.
Speaking in Rome, Marco Arcelli, Advisor to the Chairman and former CEO of ACWA Power, described a fragmented global race in which the decisive factor is no longer only technology or cost, but speed – with China “really powering ahead” on green molecules like hydrogen and ammonia while, in his words, “Europe is standing still.”
The choice he put to the continent for 2026: keep “fighting the emergency,” or build a lasting “structural advantage” on renewable molecules whose costs, once built, stay predictable; “you invest, it’s there forever.”
Closing that gap means widening the supply mix, not narrowing it. Nuclear is re-emerging as one option:, argued that Europe is finally reopening the long-closed debate on nuclear fuel recycling, reframing spent fuel not as waste but as a reserve that could power the continent “for hundreds of years.” Only 0.5% of the energy in uranium has been used so far, he noted, “we can still extract 200 times the energy that we have.” Gas, meanwhile, remains the near-term stabilizer. Dr. Mohamed Farouk of ADES Holding warned that Europe still imports “60% of its energy needs” and “97% of the oil needs,” and called for renewed exploration in the Mediterranean, Black Sea, and North Sea to sit alongside renewables and reduce volatility.
Supply is only half the problem; getting power where it needs to go is the other. Regulatory upgrades are critical, especially in the Global South. Despite abundant renewable resources, Latin America loses 17% of its electricity in transmission and distribution, three times the rate of North America, and many parts of the region generate more power than they can reliably move.
For many speakers, the deeper bottleneck is not ideas or capital but execution. Doris Honold, Board Member of the Voluntary Carbon Market and Vice-Chair of German state-owned energy company SEFE, argued that Europe already holds the tools; carbon markets, savings, an emerging grid package, and trillions in savings that could be mobilized, but struggles to channel that money into infrastructure. Her proof point: Germany built a floating LNG terminal in under six months when the will was there. The real constraint, she said, is permitting, not engineering.
Beneath the visible infrastructure lies a less visible dependency: critical minerals. A second Rome session, Energy Trilemma: Critical Minerals & Supply Chains, turned to how resource-rich and consuming regions can work together. Ilan Goldfajn, President of the Inter-American Development Bank, noted that Latin America holds “40% of the world’s critical minerals,” but warned that the stakes reach far beyond the sector: without a safe and larger supply, he cautioned, the wider technology boom simply will not happen at a reasonable price. Nor is simple extraction enough, supplying regions need value-added industry and jobs, or the disparities that make secure supply chains fragile will only grow. He pointed to the IDB’s “USD 4–5 billion pipeline” in mineral and infrastructure projects as a way to connect capital with need.
Ana Cabral, CEO of Sigma Lithium, framed the requirements as a “holy triangle” of scale, low cost, traceability, and sustainability, stressing that any supply chain, in Europe or elsewhere, has to be cost-competitive to survive. Europe cannot secure these inputs alone, she argued; it must integrate with regions like Latin America rather than waiThe wildcard across all of this is artificial intelligence. While AI is currently expanding energy demand, it also has the potential to reduce consumption and raise efficiency; improving forecasting, optimizing grids, pricing climate risk more accurately, identifying carbon sequestration opportunities, and unlocking new flows of energy-transition finance. The real question is governance: ensuring AI accelerates efficiency gains without pushing demand to unsustainable levels.
By analyzing energy consumption patterns and identifying opportunities and mechanisms, organizations could potentially reduce energy consumption by 20% in the first year.
Above all, the transition has to work for everyone. Equity doesn’t happen by default; it’s a design choice. Local jobs, social tariffs, and regional grids and pipelines can cut costs while raising reliability for the countries that need it most.
Solving the energy quadrilemma will take coordinated action across technology, policy, finance, and society. The message from Rome was consistent: Europe has much of the capital, the tools, and the resources it needs; what it lacks is the speed to deploy them. Close that gap, and the transition can move faster, cost less, and spread its benefits more widely.
The 10th edition of the Future Investment Initiative (FII10) will take place in Riyadh, Saudi Arabia, from October 26–29, 2026, at the King Abdulaziz International Conference Center. Marking FII’s 10th anniversary, the milestone edition will convene heads of state, sovereign wealth funds, institutional investors, and leading innovators around the forces reshaping global markets, from AI and emerging technologies to sustainable energy and climate solutions, the global economy, and geopolitics.
POWER Magazine explained why 2026 could see a major acceleration in the energy transition. With technology no longer a roadblock to emissions reductions, the question today is how operators can make the most of the assets that are already available to address the energy trilemma.
With electricity demand rising faster than the grid can handle, Forbes explored the need for faster, more predictable permitting. Without it, the U.S. risks shortages in both fossil and renewable energy, leading to high costs and unmet demand.
J.P. Morgan analyzed the promising investment opportunity in Latin America’s energy infrastructure, as renewable production expands and increasing demand strains the grid. The bank believes long-term growth factors such as urbanization, electrification, digitalization, and population will drive infrastructure development.
Dr. Mohamed Farouk, Vice Chairman and Group CEO of ADES Holding, examines the energy trilemma facing the world today. In this FII TV interview, he explores how energy security, affordability and sustainability are shaping the infrastructure and resilience of the global energy supply chain.
Davide Zardo, Italy Zone President at Schneider Electric, discusses the challenges shaping Europe’s energy security. In this FII TV interview, he explores the region’s reliance on fossil fuels and how the rapid growth of AI data centres can be powered through more resilient and sustainable energy infrastructure.
