Several major companies, including Amazon and Google, have pledged to support the goal of tripling the world's nuclear energy capacity by 2050.

However, this commitment was made during the CERAWeek conference in Houston, with other signatories such as shale company Occidental and Japanese firm IHI Corp. The World Nuclear Association (WNA) facilitated the pledge and expects more industries, including maritime and aviation, to join in the coming months.

Nuclear energy currently accounts for 9% of the world's electricity, produced by 439 power reactors. As large tech companies like Amazon and Google pursue nuclear projects, including small modular reactors, the demand for uranium, essential for nuclear technology, has surged.

However, uranium supply remains constrained, mainly coming from Kazakhstan, Canada, and Australia.

With high demand, uranium prices reached a 16-year peak last year, driven by supply disruptions during the COVID-19 lockdowns.

Despite this, global nuclear power generation continues to be concentrated in just a few countries, with 411 reactors in operation as of early 2025, providing a combined 371 gigawatts of capacity.
