The PANGEAS Momentum Index
Which regenerative systems are winning?
An Olympics-style tracker of momentum across energy and frontier technology — solar, wind, EV adoption, nuclear fission, grid storage, and lesser-known contenders like fusion, quantum computing, enhanced geothermal, and tidal power. Every ranking is sourced.
Two kinds of category here, clearly marked. "Data-grounded" categories (solar, wind, EV, nuclear fission, storage) are ranked from real published capacity and investment figures. "Illustrative" categories (fusion, quantum computing, enhanced geothermal, tidal) don't have standardized comparable data yet, so their rankings are an editorial judgment call, not a measurement — never presented as harder data than they are.

Medal table
One medal per category the country ranks in, across all 9 tracked categories.
The categories
More new capacity than any other energy source on Earth in 2025.
🥇 China
One country holds more than 40% of all installed capacity.
🥇 China
The volume leader and the adoption-rate leader are different countries.
🥇 China
One country is building more than six times the reactor capacity of its nearest rival.
🥇 China
Two countries hold nearly three-quarters of the world’s installed capacity.
🥇 China
No plant anywhere has put electricity on a grid yet — this field is a genuine toss-up.
🥇 United States
One concrete 2026 milestone: the first commercial-scale project set to deliver grid power.
🥇 United States
A three-way field split across three different definitions of "winning."
🥇 United States
The smallest category here — but 2026 has the most credible project pipeline this tech has ever had.
🥇 United Kingdom
