4.5 gigawatts is about the equivalent of 5 nuclear plants. The last nuclear facility built in the US took approximately 14 years to complete. Something tells me Sam will not wait that long. The fastest way to achieve that capacity is through fossil fuel generators. If LNG (the cleanest of fossil fuels) is used, the generator will emit around 2.7 million tonnes of carbon each year, which is ⅔ of the 2023 CO₂ emissions of the entire U.S. state of Vermont. We are well on track for AI consuming 12% of US energy by 2028.
