Frequently asked questions
What is CoolPower Index?
An independent, vendor-neutral guide to data centres from the grid to the rack: markets, projects, policy, AI, and the cooling and power equipment that keeps it all running.
Who is it for?
Engineers, buyers, investors, journalists and anyone curious about why AI needs so much power and cooling. You do not need to be an expert. Jargon links to the glossary.
Where do the numbers come from?
Every figure links to its source, such as a company filing, an official statistic, a maker's datasheet or a named news report. The sources page lists them and the methodology page explains how we check them.
Is it free?
Yes. Reading the site is free and you do not need an account.
Do suppliers pay to be listed or ranked?
No. Payment never changes editorial descriptions or the order of the main supplier lists. Every paid placement carries a visible Sponsored label.

A free weekly email with the week's main changes. You confirm by email before anything is sent and can unsubscribe at any time.
