Modern AI data centers consume enormous amounts of power, and it looks like they will get even more power-hungry in the coming years as companies like Google, Microsoft, Meta, and OpenAI strive towards artificial general intelligence (AGI). Oracle has already outlined plans to use nuclear power plants for its 1-gigawatt datacenters. It looks like Microsoft plans to do the same as it just inked a deal to restart a nuclear power plant to feed its data centers, reports Bloomberg.

Can you explain how wind and solar get cheaper over time? Especially wind, those blades have to be replaced fairly often and they are expensive.

With nuclear, you're talking about spending money today in year zero to get a nuclear plant built between years 5-10, and operation from years 11-85.

With solar or wind, you're talking about spending money today to get generation online in year 1, and then another totally separate decision in year 25, then another in year 50, and then another in year 75.

So the comparison isn't just 2025 nuclear technology versus 2025 solar technology. It's also 2025 nuclear versus 2075 solar tech. When comparing that entire 75-year lifespan, you're competing with technology that hasn't been invented yet.

Let's take Commanche Peak, a nuclear plant in Texas that went online in 1990. At that time, solar panels cost about $10 per watt in 2022 dollars. By 2022, the price was down to $0.26 per watt. But Commanche Peak is going to keep operating, and trying to compete with the latest and greatest, for the entire 70+ year lifespan of the nuclear plant. If 1990 nuclear plants aren't competitive with 2024 solar panels, why do we believe that 2030 nuclear plants will be competitive with 2060 solar panels or wind turbines?
