Artificial intelligence has created an unexpected problem.

Training and running increasingly sophisticated AI models requires enormous computing power, and the data centres housing those systems are consuming electricity at an unprecedented rate.

As grids struggle to keep up, technology companies and energy developers are searching for reliable power sources beyond conventional renewables.

One of the most surprising contenders comes not from a power station, but from dairy farms.The answer lies in renewable natural gas (RNG), according to the US Department of Energy, a fuel produced by capturing methane released from decomposing cow manure.

Instead of allowing this potent greenhouse gas to escape into the atmosphere, specialised facilities convert it into pipeline-quality gas that can generate electricity for homes, businesses and, increasingly, AI data centres.
