Data centre boom is wrecking net zero targets, with US and Australia leading the buildout

Data centre construction is expanding so fast that it is colliding with national emissions goals. This MacroBusiness piece argues the buildout, led by the United States with Australia second, is on track to wreck net zero targets. The numbers come from CBA and Knight Frank 2024 estimates, and the article notes proposed projects have grown since then. The core problem is timing. Data centres need reliable power quickly, while wind, solar, storage, and transmission take years to connect. If that load lands before the grid is decarbonized, utilities will lean on gas to keep the lights on. That dynamic matters for anyone tracking carbon markets or grid policy, because it affects both electricity prices and the emissions intensity of demand. For readers, the useful follow-up would be an updated count of projects under construction versus announced. The 2024 estimates are already behind the current pipeline.

Short piece but the point lands. If data centre load connects before the grid cleans up, the shortfall gets filled with gas. The 2024 Knight Frank numbers are already stale, since AI load forecasts have jumped since. Worth tracking how much of this pipeline is actually under construction.

The construction vs announced distinction is the key one. Data centres can go up in 18 months, but a transmission upgrade can take a decade. That timing mismatch is why peaker gas keeps getting a look. I would like the CBA chart redone with current queue data.

Emissions accounting will decide how messy this gets. A data centre with a dedicated renewable PPA is a different story from one buying grid power at peak hours. The article skips that, but it is where the policy fight lands.

Australia being second behind the US for data centre investment is a bigger deal than it sounds, because the NEM is a small grid. A few large loads in the wrong spot can push back coal retirements or force new gas peakers. That directly undercuts state targets.

Would like to see the same chart split by firm vs intermittent power. Hyperscalers are shopping for 24/7 clean energy deals, which changes how storage and geothermal get priced. The emissions outcome depends on whether those contracts actually add new generation.
