Uncovering the energy behind the screen

Every search, stream, and AI generation runs in a data center that burns electricity and water. Drag the activities to compare their real-world impact — bump them together, and tap any one to see the figure and follow the evidence to its source.

Your prompt is a drop. This is the ocean.

A single task is tiny — but billions happen every day inside warehouses of humming, heat-bleeding servers. Here's the scale your screen hides.

Global data-center electricity

~485 TWh / yr (2025)

Projected to nearly double to ~950 TWh by 2030 — more than Japan uses today. — IEA, Energy & AI (2025)

Where that energy goes

Cooling ~40%
Compute ~40%
Infrastructure ~20%

Cooling can rival the computing itself — and it often drinks water to do it.

Fun fact Generating one AI image can use roughly 10× the energy of a plain email — and AI video is far higher still.
Reality check A modern AI text reply is now estimated near a single web search — the footprint is in the scale, not your one question.

Add up a day of digital life.

Drag tasks into your day (or tap to add) and watch the running total — and what it adds up to in things you can picture.

Make it yours — then take it with you.
