HEY FRIENDS!! Did you know that Australia - #2 in the world for data centre investment - is now formally missing its climate targets thanks in large part to the resulting surge in power demand?

It's massive news - @crikey.com.au let me NERD OUT to explain why:

This piece is well worth your time, and it intersects very strongly with

- The whole thing of non-fossil resources serving new data centre load instead of cutting down on fossil generation (eg, the Google deals etc)

- The way fossil fuel companies use traditional predictive machine learning to dig

This is a nice example of what I've been talking about on the 'what are we doing any of this for' question.

A unit of energy freed up by household energy efficiency can help in a lot of ways: but not *multiple* ways. It either serves new data centre growth, or it helps cut down fossil fuels.

The question in my mind: putting aside all the issues with this (including the prominence of RECs, whether it's mandatory, etc) - will it help the power grid's emissions actually fall?

If all the new renewable energy is being diverted to service data centres, fossil fuels don't get crowded out....

All the lip gloss being put on the AI boom as somehow good for climate or the energy transition is masking that, at the present moment, it's a disaster.

As you can guess: this is not a failure for hydrogen in any sense of the word. The goal was not to use hydrogen in gas grids, it was to offer a cynically fabricated promise of a solution to allow for more time to kill regulations and fight electrification.

And it absolutely worked:

Three people were arrested by the police at a data centre hearing in the US -->>>

www.datacenterdynamics.com/en/news/thre...
Three arrested at data center hearing in Port Washington, Wisconsin Unlikely to help the data center's case December 05, 2025 By Jason Ma Have your say Three people were arrested in Port Washington, Wisconsin, after they interrupted a Tuesday meeting held by the local authority to discuss a potential data center project. Although the meeting did not concern the proposal for the 902MW, so-called ‘Lighthouse’ data center, which will be developed by Vantage Data Centers as part of OpenAI and Oracle’s Stargate infrastructure project, the first thirty minutes of the meeting were taken up by public comments in opposition to the facility. Vantage Data Centers – Vantage Data Centers Video footage of the incident shows police arresting three women, among them Christine Le Jeune, a member of the non-profit organization Great Lakes Neighbors United. Le Jeune had made a speech criticising the project and the Port Washington Common Council, but she was forced to conclude early after going over the three-minute time limit on public comments. This was met with applause and brief shouting, which subsided before the next speaker began her speech. A police officer can then be seen speaking to Le Jeune and two others. More officers then gather around, and video footage eventually shows officers dragging all three individuals across the floor before handcuffing and escorting them out. Police told Fox that two of the women were arrested because they dropped to the ground and grabbed Le Jeune to prevent her from being taken out of the premises. Earlier in the meeting, a member of the Council had asked members of the audience to “refrain from interrupting anyone during their public comment portion.” Otherwise, they would be removed. Police also said that they had given multiple warnings to the crowd not to disturb the meeting. But commentators online have questioned whether the arrest constituted an overreaction to the actions of the three individuals. This incident will likely…

T1 Energy Chair & CEO Dan Barcelo, right, meets with U.S. Vice President JD Vance on the sidelines of a policy conference in Washington D.C. AUSTIN, Texas and NEW YORK, Nov. 21, 2025 (GLOBE NEWSWIRE) -- T1 Energy Inc. (NYSE: TE) (“T1,” “T1 Energy,” or the “Company”) Chairman and CEO Dan Barcelo held a discussion with U.S. Vice President JD Vance Thursday on the sidelines of a policy conference in Washington D.C. “It was an honor to meet with Vice President Vance and discuss the resurgence of American energy and manufacturing,” said Dan Barcelo. “At T1, we are investing in energy from America, for America and by Americans. We are grateful for the Vice President’s time and attention to these critical matters. We want to thank the Vice President and the Administration for their pro-American growth economic and trade policies that have been foundational for T1’s strategy to build a domestic solar supply chain that is scalable, reliable and low cost.” As previously announced, T1 Energy is moving forward with anticipated plans to start construction of the 2.1 GW phase of its G2_Austin solar cell fab before the end the year. In October, T1 raised a meaningful portion of the capital required to begin project construction through equity capital raises. This first phase is expected to begin producing solar cells in the fourth quarter of 2026, cost $400 - $425 million with a workforce of about 1,700. T1 is committed to strengthening American energy dominance, reshoring manufacturing and establishing domestic solar supply chains. T1 owns and operates one of the world’s most advanced solar module facilities, G1_Dallas, in Wilmer, Texas. It is expected to produce between 2.6 and 3.0 GW of solar modules in 2025.

While em-dashes are diagnostically unreliable, it undermines the legitimacy of real writing/scholarship. And when real can't be discriminated from false, the false can thrive.

Glad you asked." SADIQ includes a photo of Twitter's algorithm code that calculates a user's reputation.
