I experienced this today. I asked a new grad to see how she could go turning a 7 min speech of mine into a long article on energy security in Southeast Asia and, she naturally used AI to do the task, but it came out so garbled and flat that I ended up just writing the damn thing from scratch.

Data centres in the Netherlands used 4.6% of all electricity in 2024, and transmission system operator TenneT expects this to double or triple to 10-15% by 2030! That means that the next 6-11 TWh/year of renewables that will be completed, will go straight to the growth of data centres.

Electricity is 23% of global final energy but delivers 37% of useful energy and powers 46% of the global economy. We don't need to replace every fossil joule. We need to replace the services. A much smaller task. Great to see the @iea.org’s new Electrification report finally measure this.

This is going to be a thread of AI greenwashing getting pumped out at New York Climate Week Here's one from today: Siemens, raking in MOUNTAINS of $$ from selling gas turbines to data centres (not mentioned) says: “we are racing to mitigate this as fast as possible" apnews.com/article/clim...
On the other hand, Eva Riesenhuber, the head of sustainability at the German automation company Siemens, and Evelyn Wang, vice president for energy and climate at the Massachusetts Institute of Technology, said AI is too important to humanity and will help tackle climate change.

Data centers adding to climate and water problems “is not forever,” according to Wang, who told The Associated Press that data centers are five years away from being water neutral and about a decade away from no longer adding to planet-warming emissions.

Acknowledging these concerns, Riesenhuber said “we are racing to mitigate this as fast as possible because we are hooked on the intelligence, and we do need the intelligence to design the future that this planet needs.”a chart showing siemens gas turbine sales will add emissions the equivalent to pakistan

Betteridge's law of headlines
Article

Betteridge's law of headlines is an adage that states: "Any headline that ends in a question mark can be answered by the word no." It is based on the assumption that if the publishers were confident that the answer was yes, they would have presented it as an assertion; by presenting it as a question, they are not accountable for whether it is correct or not.
