Data centers are a growing slice of electricity
AI hype meets grid planning — still single-digit globally.
In 2026, data centers still take only about 2% of global electricity, per IEA estimates — a reality check on the AI power hype. The stakes are in the trajectory: demand is climbing fast and landing on specific grids, forcing planners to fit an AI buildout alongside every other call on the system.

Context
Data centers' roughly 2% share sits beside the rest of global electricity on the grid: Asia & the Pacific holds 51%, Africa 27.4%, and the Americas 19.6%.
A small global average conceals sharp local concentration. Data center demand clusters in a handful of hub markets, so the grids serving them face loads far above the world average — the crux of the grid-planning challenge.
The ~2% is a snapshot, not a ceiling. With AI capacity still scaling up, planners treat data centers as a fast-growing source of new demand — the reason this single-digit share keeps making headlines.
IEA data centre electricity demand estimate ~2%.
