Tasmania’s Data Centers Accelerate Climate Impact Amid Renewable Gap
Tasmania is a great case study of how data centres in Australia are worsening climate change - No real plan for truly new renewable energy - Electrification of heavy industry struggles while big tech breezes through https://www.afr.com/companies/infrastructure/26-000-nvidia-chips-15pc-of-tasmania-s-power-does-this-ai-factory-add-up-20260424-p5zqs1
Data Centres Undermine Net‑Zero Goals, Report Shows
A great write-up in The Saturday Paper of a big new report from Greenpeace Australia Pacific which I led. It is heartening how seriously our warning has been taken, and how a whole bunch of stories that have come out in...
Data Centers Ranked as World's Second Largest Gas Turbine Buyers

War Fuels Fossil Profits, Not Climate Progress
It is pretty important not to be preemptively triumphant about the war doing anything net good for climate, emissions and decarbonisation. The amount of cash fossil fuel companies are amassing right now is beyond belief. They will use that money...
Microsoft's Actions Reveal Climate Ambitions Already Abandoned
A reminder, in the context of Microsoft dropping its 24/7 clean energy procurement goals - the company has *ALREADY* dropped its broad climate ambitions. You can determine this by looking at what they do, not what they say. https://ketanjoshi.co/2025/05/31/the-life-and-death-of-microsofts-moonshot/
Norway Prioritizes Profits Over Climate, Sells Gas to Europe
It is with a heavy heart that I announce Norway must bravely and selflessly continue to sell ultra-expensive planet-wrecking gas to Europe, including opening up 3 new previously-closed gas fields. This hurts* us more than it hurts you and your...

A pretty nice example of the function of a very specific type of lie: "we can fix this later". It's just mind-blowing because it relates to one of the single most harmful planned data centres on Earth. https://www.sltrib.com/news/environment/2026/05/07/oleary-says-box-elder-data-center/ https://ketanjoshi.co/2026/02/17/big-tech-greenwashing-report/

Kenya's New Data Center Threatens Half‑Country Power Outage
“To switch on that one data center, we would need to shut off power for half the country,” he said of the project. “That’s when I knew there was a problem.” https://www.semafor.com/article/05/06/2026/energy-shortfall-problem-scuppers-kenyas-1b-microsoft-data-center

Anthropic's Claude Runs on Polluting xAI Data Center
