  • E85 is inefficient to make in the US because the climate isn’t right to grow sugarcane (except in Hawaii and maybe south Florida, I guess?). I hear it works pretty well in Brazil, though.

    The biofuel that makes sense for US farmers to produce is biodiesel, but unfortunately relatively few vehicles are diesel.

    IMO biodiesel is the solution we should be pursuing for things like aviation, rural car owners, and as an interim fuel for long-haul trucking (until it can be abolished in favor of going back to trains) that are relatively hard to electrify.


  • It’s at least true that biofuels made from fast-growing crops like soy or sugar cane are carbon neutral (if you assume the farm equipment also runs on biofuel and no other petroleum-derived inputs are used) because they’re part of the short-term carbon cycle, right?

    If so — if the cut-off for “renewable” is definitely longer than a year, definitely shorter than millions of years, and apparently also shorter than hundreds of years — then I’d like to know where scientists (not industry shills) have decided it actually lies. Would the forest industry’s position be valid in the context of e.g. a slash pine tree farm?


    Honestly, I’m inclined to see a very strong distinction between burning wood and burning fossil methane, as long as you’re not talking about chopping down an old-growth forest or something like that. (And as long as the methane you’re comparing to isn’t from a short-term cycle source like landfill gas, for that matter.)




  • Honestly, I don’t think it’s possible to get by just trusting any particular guide without developing at least some actual understanding of the concepts underlying what you’re doing. The field is just too wide and rapidly changing for any source of info to be authoritative (and stay authoritative indefinitely after the guide is written), so it’s super important to develop the skill of looking up multiple different and possibly conflicting approaches to the task, thinking critically about them, and then synthesizing your own approach that works for your specific situation.







  • Having shared assets to maintain is legitimate, but the vast majority of HOAs (those governing single-family neighborhoods) don’t really have that as an excuse. Even if they do have something to maintain, like a private street or a pool, it’s only because the local government was shirking its responsibility to provide what should have been public infrastructure.

    (And that’s why they’re so common: because low-density development is so ruinously unsustainable, governments heavily encourage developers to establish HOAs so that the time bomb of future maintenance is the homeowners’ problem instead of bankrupting the city.)
