The IEA estimates that deploying grid-enhancing technologies and updating connection rules could unlock up to 1,600 gigawatts of those queued projects without building entirely new transmission lines. However, the agency warns that annual investment in electricity grids must rise by roughly 50 percent by the end of the decade to keep pace.
Emerging economies will account for 80 percent of additional demand, with China alone projected to add consumption equivalent to the entire European Union. Meanwhile, carbon dioxide emissions from electricity generation are expected to remain roughly flat through 2030, but only if clean energy projects actually get connected on schedule.

The IEA's Electricity 2026 report reveals that renewables and nuclear are on track to supply half of global electricity by 2030, but over 2,500 gigawatts of clean energy projects are stuck in grid connection queues worldwide. Annual grid investment must rise by 50 percent to keep pace with surging demand driven by AI, electric vehicles, and air conditioning.
Clean Energy Hits a Milestone, Then Hits a Wall
The International Energy Agency's latest Electricity 2026 report delivers a striking finding: renewables and nuclear power are on course to supply half of the world's electricity by 2030, up from 42 percent today. Renewable generation drew level with coal in 2025 and is now pulling ahead. But behind this headline lies a far more complicated story about the infrastructure needed to deliver that power.The Grid Backlog Crisis
More than 2,500 gigawatts of projects worldwide, including solar farms, wind installations, battery storage facilities, and data centres, are currently stuck in grid connection queues. These projects are approved and ready to build, but they simply cannot plug in to ageing electricity networks that were never designed for this volume of new generation. This backlog now represents one of the single largest threats to the energy transition.The IEA estimates that deploying grid-enhancing technologies and updating connection rules could unlock up to 1,600 gigawatts of those queued projects without building entirely new transmission lines.

Demand Is Surging on Multiple Fronts
Global electricity demand is forecast to grow by more than 3.5 percent annually through 2030, driven by the electrification of industry, the expansion of electric vehicles, rising air conditioning use in a warming climate, and the rapid proliferation of AI-powered data centres. The IEA says this growth is equivalent to adding more than two European Unions' worth of electricity consumption by the end of the decade.Emerging economies will account for 80 percent of additional demand, with China alone projected to add consumption equivalent to the entire European Union.
