[ THE OFFICIAL IEA DESIGNATION ]
Twenty years of power generation history. Ten years of planned future. Five nations that light the world — on one chart. Toggle countries, switch metrics, and trace the policy decisions that bent the curve.

China now generates 2.3 times more electricity than the United States. In 2005, the US led the world. The gap is the story of this chart.
Share of US commercial load growth this decade expected from AI data centers. Compute is the new heavy industry — and it runs on the grid.
China's share of global electricity demand in 2025. Grid scale is industrial scale: steel, chips, batteries, and AI training all follow the power.
India's generation growth since 2005 — a grid built for 1.4 billion people, and still the fastest-growing power sector among major economies.
EVs, heat pumps, semiconductor fabs, and AI models all draw from the same wall socket. The nations that build generation fastest set the pace for everything downstream — manufacturing, medicine, defense, and the direction of the global economy. That's why the IEA says we've entered the Age of Electricity.
2005–2025: The most massive power-sector expansion in human history — from 2,500 TWh to over 10,500 TWh, growth of more than 320%. Fueled first by heavy manufacturing and urbanization, then by an aggressive wind-and-solar buildout in the 2020s. By 2025 China represented over a third of global electricity demand.
2030–2035: Projected to hit 13,757 TWh by 2030 and ~15,500 TWh by 2035, driven by economy-wide electrification (40%+ by 2035), digital infrastructure, and EVs. Massive "clean energy bases" in the western deserts aim to push wind and solar past coal as the primary sources of generation.
2005–2025: Nearly two decades of flat demand — structural shifts to services plus aggressive efficiency standards held growth to ~0.6% a year. Then 2024–2025 broke the pattern: demand surged ~3% annually to 4,520 TWh on reshored manufacturing, heat pumps, and the onset of the AI data center boom.
2030–2035: A major growth phase begins. With AI data centers expected to make up roughly half of commercial load growth, demand is projected to cross 5,000 TWh by 2030 and reach 5,400 TWh by 2035 — requiring rapid grid expansion and a surge of natural gas, solar, and battery storage.
2005–2025: Generation nearly tripled, from 705 TWh to 2,083 TWh — universal household grid access, "Make in India" industrialization, and escalating cooling demand from rising summer temperatures.
2030–2035: The fastest-growing power sector among major economies. Central Electricity Authority plans project ~6.4% annual growth to 2,840 TWh by 2030 and 3,365 TWh by 2035 — coal kept for stability, but growth rooted in a 500 GW non-fossil capacity target led by solar PV.
2005–2025: Slow, steady growth from 954 TWh to 1,193 TWh on a gas-dominated system with significant nuclear and hydro. Sustained by energy-intensive resource extraction in Siberia and a notable rise in domestic crypto mining.
2030–2035: Official strategy projects moderate growth to ~1,250 TWh by 2030 and 1,320 TWh by 2035 — constrained by lost European export markets, partly offset by new eastward transmission links to China and domestic industrial projects.
2005–2025: The only major nation with negative growth — from 1,153 TWh down to ~1,030 TWh. The 2011 Fukushima disaster shuttered the nuclear fleet and triggered aggressive conservation; shrinking demographics added to the decline.
2030–2035: The decline has officially reversed. Domestic semiconductor manufacturing (Rapidus in Hokkaido) and AI data hubs pushed transmission operators to revise forecasts upward — 1,065 TWh by 2030, 1,100 TWh by 2035, met by nuclear restarts and offshore wind.
Methodology notes: All values are terawatt-hours (TWh) of annual electricity generation. 2030/2035 figures are national-plan and analyst projections, not guarantees. Per-person figures use approximate UN population estimates for each data year. "Share of top 5" uses these five countries as the denominator, not total world generation.
