How To Read This Taxonomy
This taxonomy is one lens on a live dataset covering 344 AI data centers across 64 countries and 202 tracked operators.
What does the energy taxonomy reveal?
It shows whether operators are leaning on nuclear, renewable PPAs, mixed grids, or fossil generation — a key lens for grid impact, permitting, cost, and ESG analysis.
Who cares about these energy slices?
Investors, utilities, journalists, and policy teams use them to understand which facilities may face power bottlenecks, sustainability scrutiny, or unusually advantaged energy access.
