We’ve all heard stories about an investment boom in the nuclear energy industry. But most think it’s something that’s still on the horizon, when in reality it’s already here.

For years, the nuclear energy sector was ignored by private investors, who saw the sector as too slow, too expensive, and too reliant on government support. 

That narrative is more than a bit outdated. It’s now fundamentally wrong.

The rapid growth of power needs for data centers and other applications has significantly increased demand for nuclear energy. So, it’s perhaps no wonder that nuclear energy’s growth trajectory has skyrocketed. 

Nearly 40 countries have signed a pledge to triple global nuclear capacity by 2050. Some critics say the 2050 goal is unattainable, but what most overlook is that investment has already doubled since 2019. 

The latest report from the International Energy Agency (IEA) showed investment in nuclear energy has surpassed $80 billion, with nearly 80 gigawatts of new plant capacity under construction, but there’s still a long way to go.
