Energy experts warned only a few years ago that the world had to stop building new fossil fuel projects to preserve a livable climate.

Now, artificial intelligence is driving a rapid expansion of methane gas infrastructure—pipelines and power plants—that experts say could have devastating climate consequences if fully realized.

As large language models like ChatGPT become more sophisticated, experts predict that the nation’s energy demands will grow by a “shocking” 16 percent in the next five years. Tech giants like Amazon, Meta, and Alphabet have increasingly turned to nuclear power plants or large renewable energy projects to power data centers that use as much energy as a small town.

But those cleaner energy sources will not be enough to meet the voracious energy demands of AI, analysts say. To bridge the gap, tech giants and fossil fuel companies are planning to build new gas power plants and pipelines that directly supply data centers. And they increasingly propose keeping those projects separate from the grid, fast tracking gas infrastructure at a speed that can’t be matched by renewables or nuclear.
