Place-first reporting on Latin America's digital ecology: data centers, networks, devices, and the sensors watching its biomes — traced to measurable energy, water, mineral, and waste flows.
When we picture the internet’s environmental footprint, we usually imagine vast server farms humming under fluorescent lights, the scramble for rare minerals, or the electricity siphoned by billions of screens. But there’s a quieter, more concentrated cost that rarely makes headlines: the brute energy needed to train a single, massive neural network from scratch. Rui …

Every time you ask a digital assistant a question or watch a video recommendation pop up, somewhere a powerful machine has done some thinking. But that thinking isn’t weightless. Behind the scenes, rows of specialized computers hum in vast warehouses, drawing electricity and throwing off heat. It’s easy to forget that these systems have a …

We like to picture the digital world as something clean and weightless—silent bits drifting through the air. But that image falls apart the moment you look behind the screen. Every search, every auto-suggest, every eerily fluent chatbot reply starts with a physical machine, somewhere, pulling current and throwing off heat. And when you scale up …
When we picture pollution, it’s usually smokestacks, gridlocked highways, or plastic swirling in the sea. But there’s a quieter kind of emission humming away inside windowless buildings all over the world: the energy burned to train enormous neural networks. I’m Rui Mendes, and I’ve been following the power flows behind the software that increasingly runs …

When we ask a machine to learn language—to chew through billions of sentences and find the patterns—we almost never ask what that learning costs. Not money, not engineering time. Something quieter and more physical. I’ve been chasing this question through research papers, energy grid maps, and water-use reports, trying to sketch the real shape of …
I used to picture forest monitoring as some solitary researcher with a clipboard, tallying trees one by one under a hot sun. That mental snapshot fell apart fast. What’s actually going on is stranger and more systemic: a swarm of satellites, hundreds of them, crisscrossing overhead, silently measuring every hectare of forest on the planet …

The A100 GPUs in Loudoun County, Virginia sit at 70°C, a steady hum you’d feel in your chest if you were standing in the aisle. Someone in São Paulo taps “generate.” A 100-page neo-noir screenplay. The model—probably a fine-tuned LLM running on a hyperscale provider—processes the prompt in seconds. Scene headings, dialogue, parentheticals spill down …
I remember the first time I saw a satellite image of a logging road slicing through a patch of Amazon rainforest. It looked like a scar—thin, deliberate, and impossibly remote. I wondered who was watching that road grow longer each week, and whether anyone could stop it before the forest canopy collapsed around it. That …
I still remember the first time I stared at a satellite image long enough to notice the change. It was a stretch of tropical forest in Rondônia, Brazil, and at first glance it was just a green smear on the screen. But when I flicked between two dates—one from January, another from June—the difference hit …
It’s weird how a forest can disappear without anyone really noticing until it’s too late. A few hectares shaved off here, a rough track cut through there, and before you know it an ecosystem that took centuries to knit itself together is just… gone. For years we tracked this loss with ground surveys, scattered reports, …
