AI data centers are consuming so much electricity that Big Tech is turning to nuclear power.

Microsoft, Google, Amazon, and Meta are making nuclear moves as AI energy demand reshapes the global power grid.

Artificial intelligence may be a software revolution, but underneath every AI model is an enormous physical infrastructure stack: GPUs, servers, cooling systems, data centers, transmission infrastructure—and electricity.

In this episode of Silicon to Software, Imran Valiani examines why the explosive growth of AI infrastructure is creating renewed demand for nuclear energy.

The International Energy Agency reported that global data centers consumed roughly 415 TWh of electricity in 2024 and projects consumption could reach around 945 TWh by 2030.

That growing demand is already influencing some extraordinary energy decisions.

Microsoft signed a 20-year power agreement associated with restarting Three Mile Island Unit 1, now known as the Crane Clean Energy Center.

But Microsoft isn't alone.

Google has partnered with Kairos Power on small modular reactor technology. Amazon has invested in nuclear projects and signed a long-term agreement involving the Susquehanna nuclear plant. Meta has sought proposals for gigawatts of new nuclear generation.

We break down:

• Why AI data centers require enormous amounts of electricity

• Why AI inference creates continuous power demand

• The cooling and thermal challenges behind high-density AI hardware

• Why wind, solar, and battery storage face challenges supplying 24/7 AI workloads alone

• Why nuclear power is attractive to hyperscale data center operators

• Microsoft's Three Mile Island agreement

• Google's nuclear partnership with Kairos Power

• Amazon's nuclear investments

• What Small Modular Reactors (SMRs) actually are

• Why SMR economics remain unproven at Western commercial scale

• The cybersecurity implications of connecting AI infrastructure with critical energy systems

• What AI's energy demand could mean for the future power grid

The AI race is no longer just about who builds the fastest GPU or the most capable model.

It's becoming a race for electricity.
