  • The problem, as I often say, is that just because something demos well and it’s easier to buy something doesn’t mean it’s going to be good in production. If you have a solar farm but you need to build a coal plant large enough to power the island anyway because you don’t have dispatchable power, then you end up with Australia, California, or Ontario, where “the cheapest power” causes electricity costs to rise. Meanwhile, In places like Norway, Quebec, and iceland, those renewables actually drove down electricity costs because the marginal cost of energy is very low and you don’t need to double up your infrastructure even if it’s expensive and difficult to build up-front.



  • Imo one of the examples of renewables that someone needs to push (and I don’t care who, whichever team does it takes the win) is geothermal in hawaii. They import massive amounts of coal to generate 90% of their electricity and thus have some of the most expensive electricity in the US.

    Easy win, it would make everyone on the islands life way better, and of course it isn’t even on the radar because it wouldn’t cost that much and it’d be really effective immediately.


  • Ya got me.

    I registered a domain 23 years ago, maintained the site in various ways, set up a threadiverse instance with the least used federated link aggregator back around 2021, Expressed opinions that got me defederated by tons of instances and pissed off most of the remainder, and stayed following this community for years, all so that I could use a bot to respond to a post.

    I don’t even know why I needed a bot at that point, since apparently I’m friggin Xanatos the chess master.


  • Feels like a category error to say that Trump is necessarily against renewable energy rather than just against specific types of renewable energy.

    A lot of greenies are against hydroelectric because even though it provides base load power for decades or even centuries, the building of reservoir and the damning of a river typically has major environmental impacts that they feel override the benefits.

    If there’s concern about offshore wind because of the potential – the actualized potential by the way in a limited number of cases – then that would explain why there would be the pushback against offshore wind.

    The problem with water is that unlike land which tends to be fairly localized, just a little bit of pollution can affect an absurd amount of water. That’s why they tell people not to dump their motor oil in the ground, because one drop of motor oil can pollute thousands of gallons of water.

    I tend to be less interested in solar because empirically speaking it seems to drive up electricity costs for actual consumers regardless of the cost of a specific kilowatt hour of electricity at peak production, and less interested in wind because sometimes it is bright or cold and the wind doesn’t blow, the Germans already have a word for this because it is relatively common.

    That being said, there’s no reason to be against good technology that actually does what it’s supposed to do, and that can mean hydroelectric, it can mean well regulated nuclear, it can mean geothermal, but just because something is marketed as green doesn’t mean that it is actually good for the environment. Everything at an industrial scale is a out trade-offs. Different people will look at things through different lenses and find different trade-offs more example and other trade-offs less acceptable.









  • What you’ve been talking about here makes perfect sense to me.

    A good chunk of myself hosting journey has been hardware. Figuring out the benefits and limitations of different thin clients, the capacity and limitations of various fanless PCs, and even stuff like worrying about the durability of ssds compared to hdds. So to say that you can’t talk about hardware doesn’t make a whole lot of sense, however, of course you want to keep it strictly scoped within the subject at hand, which is self-hosting. My driver work on the haiku operating system may be interesting, but if it doesn’t somehow relate to self-hosting, this just isn’t the place for it.


  • It’s based on conduit, which itself is really a lot better for self-hosting than synapse or dendrite.

    I ran conduit on an atom d2550 alongside other services and it basically idled. Running synapse or dendrite on the same machine made the whole machine max out permanently.

    Irc is fine, but not federated…


  • interesting piece of trivia: In 2003ish, there was a major power outage across the northwestern US and much of eastern Canada. One major issue was that the grid became desynchronized so resynchronizing was a major problem they had to solve to bring the grid back up. The province of Quebec uses high voltage DC lines (and also massive amounts of hydroelectric power, but that’s a conversation for another day) so they didn’t have that same problem and had returned their power to normal long before the rest of the region.


  • I really like this post, it gets down to nitty gritty brass tacks and brings some data.

    That’s usually the thing that gets me grumpy about such conversations, people don’t bother discussing the realities of actually doing the thing, they just trade feel good articles about how everything is fine.

    One thing about the paper is, the cost of high voltage DC lines is likely assuming you’re on land. Bringing the energy in from sea could be even more expensive, since you need much more expensive equipment, the environment is brutal, repairs involve sending people and material into that environment, and I have a feeling but I don’t know, I think that the movement of the offshore wind turbines could be mechanically stressful on cables that are relatively safe up in the air only dealing with wind (and they still can cut right through insulators swinging in the wind and vibrating at 60hz)
