Ooh, look. When we covered the climate impacts of machine learning (“AI”) on Rare Earth in June we found it really frustrating that none of the tech companies would tell anyone the water and energy costs. Now Google has made at least some of it public. More of this! (and preferably raw data too).
technologyreview.com
In a first, Google has released data on how much energy an AI prompt uses
It’s the most transparent estimate yet from one of the big AI companies, and a long-awaited peek behind the curtain for researchers.

More zero-click searches, same revenue for Google, less visibility for publishers? Three things to read together on (1) how users respond to AI summaries, (2) what the company says it means for volume of queries and revenue, and (3) outside analysis on publishers’ visibility 1/4

Data centers das big techs viraram símbolo de “progresso” no Brasil: ganham isenção, água, energia e terrenos. É a mesma história de sempre: exploram o território enquanto lucram lá fora. Um colonialismo versão 2.0, mas agora com cabos e servidores no lugar de navios.
