  • I’ll take “Tell me you were never actually an ally without telling me you were never an ally” for $100 Alex.

    This gatekeeping is exactly what they're lamenting. Alienating people who have been fighting for equal rights for decades because they're not pure enough is why the culture is turning.

  • Control. These people have almost no agency in their lives. They typically don’t work, or if they do, choose low responsibility roles with few demands on them. They also tend to live meagre lives, often living with parents and flat mates. They tend to be socially awkward, often self diagnosing autism and other afflictions. They revel in their victimhood, and choose to construct grand narratives about how their failures are the fault of society, and not them.

    Consequently, they have very little control over their lives, and very low self esteem. They seek out control in the only place they will ever experience it: online communities.

  • My home is an ad free zone. I pay for Premium and I’d pay for no commercials, but since that isn’t an option, I block them.

    This war on SponsorBlock is reminiscent of the 80s and the war on VCRs. Advertisers tried to make taping things illegal because they argued people would fast forward through commercials. They were right, but that doesn’t mean we don’t have the right to choose what we watch.

  • How is reducing farmland from 4 to 1 billion hectares zero impact?

    In the context of our discussion, it has minimal impact on climate change. The scope of harm is really limited to deforestation, but this has minimal impact on CO2 emissions as a proportion of all other output.

  • But an additional effect you have when considering the whole of europe is interconnection. The geographic spread of renewables lowers storage requirements.

    Yes I reference this when I explain that, "economical line transmission distances cap out at around 500km." In other words, hydro storage can't be utilised all over Europe. Hydro storage in the Alps, for example, cannot power Danish homes.

    Thanks for the link! I hadn't considered hydrogen as viable yet but technology is improving rapidly. I think the major barrier at present is the conversion loss. Between 60-70% of energy input is lost, but I am optimistic this will improve in time. Further, perhaps at scale, close to areas of high variable energy output, this technology makes sense today.

    I agree with you on batteries. Tesla made a huge impact on the world energy market when they proved their battery farm concept in South Australia. It's only used to reduce spot pricing (demand spikes which last milliseconds to minutes), but producers were bilking the public out of millions in those moments, and Tesla significantly cut their profits.

  • I appreciate the affirmations but I've spent enough years on this planet, and attempted various diets enough times, to know what I like and do not like. I like meat. Many people like meat.

    My tastebuds are definitely more important than the almost zero impact I have explained such a diet has on the planet. You slipped up a bit there and fell into ethical concerns. Remember, this is a discussion about the impact meat has on the environment. Or is your argument not in fact about the environment at all?

  • Thanks for the study. Super interesting. So they used Grand Canary Island as a proof of concept for the study. The two proposed storage mechanisms were li-ion batteries and hydro. They propose 5.82GWh, which is the equivalent of 108,000 of the cheaper 54KWh Tesla batteries. Hydro works well there because of their 2,000m elevation over a short distance. Their daily energy production is around 17.5GWh, and their proposed storage solution appears sufficient given the variability in predicted wind.

    It looks like a good use case for this location, but I'm not convinced this can be scaled to entire continents. Let's take Europe (because I'm familiar with the data in Europe). Much of the continent is very flat. Denmark, Southern Sweden, Netherlands, and Northern Germany, for example, cannot take advantage of hydro storage, and this comprised the largest storage component of the proposed solution. In fact, given the elevation requirements, hydro would comprise a much lower proportion of storage than batteries, if scaled across Europe.

    This leads to the second problem. Even if we assumed all of Europe had as high an elevation gradient as the Grand Canaries, the power requirements are on a complete different scale. Using the same ratios, with 37% of storage coming from batteries, and 89% of daily storage required to smooth variance, Europe would require 106.8 million Tesla batteries. For reference, Tesla has only ever produced around three million batteries in its entire existence. In reality, Europe would require far more batteries than this, as hydro storage is not possible in many locations, and economical line transmission distances cap out at around 500km.

    We need new battery technologies or other means of economical storage to make such a grid work in Europe. I suspect the numbers are similar in the U.S. Biomass and geothermal help close the gap, but not nearly enough.

    For posterity, I'm not proposing that at present, renewables can't comprise an even larger share of the existing mix. I'm arguing that renewables cannot comprise the entire mix at present.

  • Do you have any proof of this other than your own conclusions? Because a lot of experts see this very differently.

    One cannot prove a negative. Can you prove that god does not exist? Typically the burden of proof lies with the one making any positive claims such as you are.

    The report you cite doesn’t appear to indicate that batteries could smooth a fully renewable grid. Perhaps I’ve missed that important part. Would you cite the page?

  • You can easily be vegan while advocating for other change like less coal.

    Sorry, but major lifestyle changes are not "easy." It's "easy" to lose weight, and yet two thirds of Americans can't do it. I like eating meat but would be willing to give it up if the juice were worth the squeeze. It's not. Instead of spending your time telling people to make major lifestyle changes with almost zero impact to the climate, why aren't you focusing on real, sustainable solutions?

    FYI the top four metrics in the image you linked are for agriculture, not meat production alone. Agriculture includes the production of plants, fruits, and grains. It's all food production.

  • The storage problem is solved it's just not necessary

    False. There is currently no technology which enables an economically viable solution for 100% renewable grids.

    Just to give you an example, Denmark's wind generation just yesterday fluctuated 92%. Over the last year, wind generation has fluctuated across Europe by more than 555%. Europe currently produces around 6,480GWh per day. To buffer even half this during periods of low wind/low sunshine would require 60+ million Tesla batteries. For reference, Tesla has only ever produced three million batteries.

    For now, power grids require reliable generation. Unless you want coal and LNG, it has to be nuclear.

  • I don’t think anyone suggested Meta is doing this out of the goodness of their hearts. I certainly didn’t write that. They want to make money.

    As for cross-pollination, it’s basically a law in SaaS now. When you expose users to something, some of them engage. Meta can’t hide the existence of other instances else there’s no point in federating. If users are other instances, and interact with users from those instances, some of them will create accounts on those instances.

  • It’s FOSS. Meta is free to spin off their own version of ActivityPub, but we don’t have to join them. The entire point of federalised instances is to allow competition like this. If Lemmy devs are dropping the ball then other developers will compete for a better user experience. Competition rocks and I’m looking forward to it.

  • Where do you draw the line for abuse?

    I can answer that very succinctly: those seeking to falsely invoke the articles under the 1951 Refugee Convention.

    There are six billion people on the planet who are poorer than Danish citizens. Denmark is a tiny country. They can’t all fit in Denmark. That’s not a solution to global poverty.
