As Use of A.I. Soars, So Does the Energy and Water It Requires
Generative artificial intelligence uses massive amounts of energy for computation and data storage and millions of gallons of water to cool the equipment at data centers. Now, legislators and regulators — in the U.S. and the EU — are starting to demand accountability.

US startup ditches towers for unique pyramid-mounted wind turbines
An innovative floating offshore wind turbine prototype was launched in New Bedford, Massachusetts. Instead of a single anchor tower, the approach uses a pyramid base that can also passively orient itself in the direction of the blowing wind.
This project cuts emissions by putting data centers inside wind turbines | CNN
WindCORES operates data centers inside wind turbines located in a wind park in western Germany, which the company says makes the centers almost carbon neutral.
NTU researchers build mini wind harvester to produce electricity from a gentle breeze | The Straits Times

Electric power emissions barely rose in H1
The globe could be "nearing the point of falling power sector emissions."
The living things that feast on plastic
Scientists are scouring garbage sites around the world for bacteria, fungi and even insects that harbor enzymes that could be harnessed for breaking down various polymers. It’s early days, but if the efforts can be efficiently scaled-up, such biological recycling could put a dent in the plastic waste problem.
A.I. tools fueled a 34% spike in Microsoft’s water consumption, and one city with its data centers is concerned about the effect on residential supply
“They were pretty secretive on what they’re doing out there,” says a former mayor about Microsoft’s data center projects.
Microsoft disclosed that its global water consumption spiked 34% from 2021 to 2022 (to nearly 1.7 billion gallons, or more than 2,500 Olympic-sized swimming pools)

Microsoft’s Remarkably Big Bet on Carbon-Absorbing Rocks
Why the tech giant is so high on Heirloom Carbon
Heirloom Carbon
Heirloom Carbon,
315,000 metric tons of carbon from the atmosphere over 10 years. For a sense of scale, that’s equivalent to about 75% of the carbon Microsoft emitted in 2022
$200 million, “based on market prices,” or $635 per ton
The process starts with limestone, which is formed from the detritus of corals, clams, and other sea creatures that use the dissolved carbon and calcium in the ocean to build their shells. Heirloom grinds up limestone and does something that humans have been doing for thousands of years — heats it in a kiln. This loosens carbon dioxide from the rock, leaving behind calcium oxide
The Carbon Emissions of Writing and Illustrating Are Lower for AI than for Humans
