Things and Stuff

If this don’t make your thing go, your wood is wet!

The promises are becoming familiar.

"We're water-neutral."

"We recycle our water."

"We use closed-loop cooling."

Those statements can all be true.

But they often leave out an important detail.

In many water-cooled data centers, a significant portion of the water used for cooling is lost through evaporation. Once that water evaporates into the atmosphere, it is no longer immediately available to the local rivers, reservoirs, or aquifers from which it was withdrawn.

AI data centers generate enormous amounts of heat, and keeping thousands of high-performance chips cool requires sophisticated cooling systems. While some facilities rely on air cooling or highly efficient closed-loop designs, many still use evaporative cooling because it consumes less electricity than some alternatives. The trade-off is higher water consumption.

In regions already facing drought or growing water stress, that trade-off has become a source of increasing public concern.

Environmental advocate Erin Brockovich has called for greater transparency around the water demands of large AI data centers, arguing that communities deserve to understand how much water these facilities will consume before construction begins.

As artificial intelligence continues to expand, so does the need for honest conversations about its environmental footprint.

Building the future isn't just about having enough electricity.

It's also about understanding where the water comes from—and where it goes.
