    One really interesting strategy the US could pursue here would be to heavily tariff solar[1] and just randomly attack wind projects[2]. Just completely self-own itself on the two cheapest energy sources.

    It wouldn't make any sense, but it would be provocative, really drive engagement.

      Maybe the tariff could encourage local manufacturing of solar? I have no idea, but I suppose that our local manufacturing could be getting killed by economies of scale abroad.

      Or I am overthinking it and solar is something that (D) politicians support so the (R) president tautologically must oppose it. Therefore we must not have nice things

        We have tried locally, with huge government backing, but that failed. But since it was an Obama initiative, a new attempt will never be tried.

        Farmers make more money from wind turbines on their land than their crop. https://ambrook.com/offrange/farm-finance/there-will-be-wind

        And that is stable money, works without rain, which crops don't.

          That's what tariffs do ... if you leave them in place for extended periods of time.

          The problem is that nobody is going to bet their business on what the tariffs will be tomorrow when it could be 10x or zero.

          Businesses are just going to stop and hold their breath until Trump goes away.

        I worked for a company making GPU clouds. The biggest problem we had for deployments was not getting GPUs -- we had plenty of those sitting in warehouses. The biggest issue was finding data center space with sufficient power and cooling. There was plenty of square footage, just not enough power for it all.

        They're now building gigawatt datacenters to handle all the GPUs.

        The big question is were to build them. There are only a few places with cheap and plentiful power. One of those is Quebec (but it's not that big and there is a lot of regulation). Another is Texas (except their grid isn't very stable). And the last is China. And you can't build a datacenter in China unless you're Chinese.

        It'll be interesting to see how this pans out. Maybe the current admin (which is big on deregulation) will make it easier to build power plants, especially nuclear ones.

        Edit: I wrote this comment four days ago. I couldn't figure out why I was suddenly getting a bunch of replies to it. Apparently when HN does a second chance, they just reset the time on all the comments. Odd, but I guess it makes sense knowing what I know about how the sorting is calculated. It's probably the easiest way.

          They aren’t big on deregulation at all. They’re big on selective regulation. They’re also big on killing any power project that isn’t oil or coal.

                          When the brits were at it (With insourced nuclear engineering and low regulatory overhead) they could crank them out every 6 - 8 years.

                          The brits let all that technical capability wither and could not do it again right now.

                          In my part of PA there are 3 in the process of going in nearby. I think the largest of the 3 is "only" 828 megawatts though. One of the others is supposed to be 300MW, and I'm not sure about the 3rd. There is another group talking about 3 more campuses with a combined power budget of 1.3GW about 55 miles from here. But then while we don't have cheap land, we do have nuclear and hydroelectric in the area, so I guess the makes it attractive.

                                                  This is honestly one of the stupidest things about this sort of policy: solar panels last 20 years and China can't take them away once you have them.

                                                  If you're doing something much more valuable with the power, then buying a lot of PV from China makes sense. If you think the panels are being unfairly subsidized then buying a lot of PV from China is effectively having the Chinese government pay you to have cheap power.

                                                  There's an enormous difference between being dependent on short term consumable resources,.and acquiring multidecadel productive assets.

                                                  The US at all points seems to not understand it's relationship with China at all.

                                                    They literally only "hurt" you if you have the local industry to harm to begin with. Otherwise, if someone else is paying the subsidy, it gives you a good for cheaper than you could have had otherwise.

                                                  My hunch: we’ll see three things happen in parallel

                                                  - AI backend providers vertically integrating into energy production (like xAI’s gas plants, or Meta’s local generation experiments),

                                                  - renewed interest in genuinely efficient computing paradigms (e.g. reversible/approximate computing, analog accelerators),

                                                  - a political battle over whether AI workloads deserve priority access to power vs. EVs, homes, or manufacturing, alongside an increase in energy prices.

                                                  You need cheap, reliable power + political/regulatory willingness + cooling. That’s a very short list of geographies. And even then, power buildout timelines (whether nuclear, gas, or grid-scale solar+batteries) move at "utility speed", which is decades, not quarters. That doesn’t match the cadence of GPU product launches.

                                                    As a short teaser: Landauers principle suggests that the energy required to erase one bit off information is bounded from below by k_BTln(2). This could lead us down a path towards reversible computing, to avoid energy costs for deleting information.

We're essentially trying to scale AI demand faster than energy infrastructure can physically respond. This creates interesting arbitrage opportunities in power-rich but compute-poor regions.
