Pumped-hydro storage cut modeled emissions by 81%

A life-cycle assessment modeled pumped-hydro storage alongside wind, grid and hydropower. Compared with a baseline without storage, the system reduced modeled greenhouse-gas emissions by 81%, while steel and cement production created environmental burdens.

AI data centres’ closed-loop cooling shifts 92–95% of water use to the grid

An open Zenodo working note tracks water use linked to 10 AI data-centre sites and provides code to reproduce its calculations. It finds that closed-loop cooling shifts roughly 92% to 95% of the modelled water footprint to the electricity grid, rather than removing it.
