its water usage efficiency represents a 40 % improvement since 2021.
The electricity consumed by Amazon’ s operations, including its data centres, was matched 100 % by renewable energy resources in 2023. Amazon has been the largest corporate purchaser of renewable energy in the world for the past five years.
AWS announced it would roll out new data centre components that reduce mechanical energy consumption by up to 46 % and reduce embodied carbon in concrete by 35 %. The sites constructed to support Project Rainier include these upgrades. The company remains on a path to be net-zero carbon by 2040.

“ Project Rainier is a massive one-of-itskind infrastructure project that will usher in the next generation of AI models”

Trainium3 chips to deploy at Project Rainier sites In an interview with CNBC, Matt said AWS is preparing to deploy Trainium3, the third generation of its AI training chip.“ It gives better performance, it gives better latency characteristics, it gets better power consumption per flop,” he told CNBC.“ That will be deployed inside of Indiana. It’ ll be deployed in many of our other data centres all around the world.”
Trainium3 is set to launch in the next few months. The chip was developed in collaboration with Anthropic, according to CNBC, with the AI company providing direct input to improve training speed, reduce latency and enhance energy efficiency.
“ When we build our own devices, we get to optimise across the entire stack to really compress engineering time and the time to get to massive scale,” Ron says. datacentremagazine. com 87
