Energy Comparison

Hydroelectric vs Nuclear

Hydroelectric and nuclear are the two most reliable zero-carbon baseload power sources for AI data centers. Hydroelectric power dominates in Norway, Canada, Brazil, and the Pacific Northwest of the United States, offering some of the lowest electricity costs globally and a natural fit for energy-intensive AI training. Nuclear is gaining renewed interest as AI operators seek 24/7 zero-carbon power that can scale to gigawatt levels — with Microsoft, Google, and Amazon all signing nuclear power deals. This comparison shows how data centers using these two power sources compare in the index.
