Geothermal Isn't Expensive: The Reservoir Always Has the Final Say Somewhere beneath a volcanic ridge, a drill bit is turning through rock that has not moved in two million years. It costs money every second it turns. And nobody on the surface — not the engineer, not the financier, not the minister who announced the megawatts — knows yet whether that well will produce steam or silence. That single moment explains almost everything people get wrong about geothermal energy. Geothermal is routinely described as expensive, slow, capital-hungry and haunted by drilling risk. Investors are reminded that tens of millions can disappear underground before a single megawatt reaches a grid. All of that is true. But it is not the whole truth. The uncomfortable question the industry keeps avoiding is this: is geothermal expensive, or is the way we develop geothermal making it expensive? Those are two completely different problems. One is geology. The other is us. Why Geothermal Refuses to Be...
When you think of Singapore, what comes to mind? Skyscrapers. Tech. Food. Green innovation. But now, add one more surprising trait to the list: geothermal powerhouse . By: Robert Buluma That’s right beneath the city-state’s highly urbanized northern district lies a blazing opportunity that could redefine Singapore’s energy story. In a recent announcement that’s set the clean energy world abuzz, scientists from NTU Singapore and TUMCREATE revealed astonishing findings from a joint geothermal drilling project. At just 1.76 km underground in Sembawang , temperatures have soared to a jaw-dropping 122°C —a record-breaker for the region, and far higher than the 70°C earlier recorded at a shallower depth in Admiralty. This isn't just hot news. It’s a revolutionary discovery that could reshape how one of the world's most densely populated nations powers its future. 🌋 A Hidden Furnace Below the Urban Jungle This project—backed by Singapore’s National Research Foundation (NRF) and th...
