Top tech companies are increasingly turning to hydrogen and nuclear energy to power their data centers, aiming for more eco-friendly solutions that can be deployed rapidly. Hydrogen-powered data centers can be operational in half the time compared to traditional grid-connected facilities, with one such center already in operation in California. As demand for generative AI capabilities surges, companies like Amazon, Google, and Microsoft are racing to establish data centers equipped with powerful GPUs, which require substantial energy resources. However, existing utilities in certain regions are struggling to meet this demand.

In addition to hydrogen, nuclear energy is gaining traction, with significant investments from figures like OpenAI's Sam Altman in nuclear startups. While nuclear power presents safety and waste management challenges, its carbon-free nature makes it appealing. Major tech firms are also exploring geothermal energy and other renewable sources to meet their ambitious emissions reduction goals. With projections indicating a dramatic increase in data center energy consumption by 2028, the urgency for sustainable energy solutions in the AI sector is more critical than ever.
