While the world watches the diplomatic theatre of the New START treaty collapsing, US–Iran nuclear talks stuttering, and analysts obsessing over the price of a barrel of oil, a far more tangible crisis is unfolding in the humid palm oil estates of southern Malaysia.

If you drive north from Singapore across the Causeway into Johor, you will see them. Massive, windowless concrete boxes are rising from the earth at a frantic pace. They are branded with the sleek logos of the digital age — Nvidia, Microsoft, GDS Holdings — and wrapped in the virtuous language of the “Green Transition.”

These are not just data centres. They are gas guzzlers. And they are about to upend Southeast Asia’s energy security more effectively than any sanctions regime or trade war. As of 2025, around 434.5 MW was in use across Malaysia’s data centres.

For the past two years, the narrative in ASEAN energy circles has been one of “transition” — a polite, bureaucratic dance about slowly replacing coal with solar, funded by carbon taxes and good intentions.

Yet physics has a way of ignoring policy papers. The arrival of the “AI boom” has crashed into the region’s fragile power grids with the force of a tsunami, exposing a truth that few in the halls of power want to admit: the digital economy is not green. It is grey, and it runs on liquefied natural gas (LNG).

The Great Singapore Extension Cord

‍

To understand the crisis, you must look at the peculiar relationship between Singapore and Malaysia. For years, Singapore has positioned itself as the green finance hub of Asia, imposing strict limits on new data centres to curb its own carbon footprint. It was a noble gesture — with a twist.

Singapore did not solve its energy hunger. It merely outsourced part of it, plugging a giant extension cord into Johor. By lifting the moratorium on cross-border data flows while keeping tight reins on domestic power usage, Singapore effectively turned its northern neighbour into its digital boiler room.

Singapore has electricity import agreements and regulatory frameworks separate from Malaysian grid planning, as part of an accelerating regional grid interconnection. Still, this does not imply that the city-state outsources all of its power usage.

The result is the “Silicon Sponge.” Johor is soaking up power capacity faster than national utility Tenaga Nasional Berhad (TNB) can build it. We are not talking about a few megawatts.

The pipeline of approved data centres in Malaysia is approaching 6 to 8 gigawatts, representative of projected future build-out plans cited by industry groups.

To put that in perspective, this is roughly one-third of Peninsular Malaysia’s entire current peak demand.

The Baseload Fallacy

‍

Here is where the “Green AI” myth falls apart. The hyperscale chips powering the AI revolution — the H100s and their successors — do not sleep. They run at near-100% utilisation, 24 hours a day, seven days a week. They demand a flat, relentless baseload of power.

Solar power, Malaysia’s renewable of choice, works when the sun shines — roughly 15% to 20% of the time. You cannot run a 24/7 AI factory on a 20% power source. Batteries are still too expensive at this industrial scale.

So what happens when a US tech giant pledges to be “carbon negative” but builds a gigawatt-scale campus in a country with a coal-heavy grid? A massive accounting trick occurs. The tech firm pays TNB a premium for “Green Electricity Tariffs” (GET), purchasing Renewable Energy Certificates (RECs) from hydro plants in the remote hills of northern Perak state.

But the actual electrons flowing into the servers in Johor? They are generated by burning gas and coal — though some operators are investing in offsets.

Data centres require significant electricity and cooling — both energy and water demands are cited as concerns by Malaysian regulators. Current actual electricity use by data centres remains in the hundreds of megawatts.

The LNG Trap

‍

This is the hidden driver of the next energy price spike. To keep these servers from crashing, Malaysia is being forced to double down on fossil fuels, even as the government highlights efforts to bolster renewable integration and encourages direct procurement of renewable power by corporate consumers.

TNB also has little choice but to commission new combined-cycle gas turbines (CCGTs) to provide the stability that solar cannot.

This fundamentally alters Malaysia’s economic DNA. Historically an LNG exporter, Peninsular Malaysia is now staring at a future where it must import massive quantities of gas to feed the Silicon Sponge. The gas fields are in Borneo; the data centres are in Johor. The pipeline capacity between them is insufficient.

The irony is stark. The “gas glut” that global traders are currently betting on — driven by new supply from Qatar, the US, and Australia — will be swallowed by the voracious appetite of the AI sector. Malaysia recently signed a 20-year LNG supply deal with QatarEnergy, signalling growing energy demand pressures and diversification of gas sources.

The price relief that ASEAN manufacturers were hoping for in 2026 will evaporate, bid up by American tech giants with infinitely deeper pockets than a local steel mill or glove factory. At the same time, energy planning must evolve in response to demand from multiple sectors, not just technology.

A Geopolitical Kill Switch?

‍

There is a final, sharper edge to this story. By concentrating so much of the Western world’s critical compute infrastructure in Johor, the US may inadvertently hand a geopolitical “kill switch” to Malaysia.

In a world where the US–Russia nuclear framework has fractured and the Middle East remains a powder keg, Washington should be wary. A significant percentage of the AI processing power that drives the American economy now relies on a power grid in a country that is fiercely protective of its neutrality and increasingly sceptical of Western foreign policy.

Prime Minister Anwar Ibrahim knows this. He is not just hosting server farms; he is hosting leverage. If the US pushes too hard on tariffs and sanctions — forcing Malaysia to choose between “clean” Western gas and cheap “grey” molecules from Russia or Iran — the lights in the server rooms might just flicker.

The era of energy transition may be fading. The age of energy survival has begun. And in the humid heat of Johor, the only shift happening is the conversion of natural gas into artificial intelligence.
