  • Isn’t peak consumption around middle of the day for most countries?

    I can’t speak to other countries, but in the US peak electricity demand generally occurs in the early evening.

    Mfw electricity being cheap to generate is not economical

    Cheap electricity is great for consumers, but not necessarily for producers. Some people might say, “well, screw producers,” but even if you take profit out of the equation, electric utilities need to be able to at least cover their expenses, and you can’t do that if the amount of electricity you’re generating relative to the demand is so high the price actually goes negative (meaning the utility is actually paying the consumer). Again, that’s good for consumers, but I’m sure you can see how that’s not a sustainable business model. And, like I mentioned before, it would be one thing if utilities could make up for this by selling for a higher price during peak, but by that point the sun is either setting or already set, depending on the time of year, so there’s just no solar electricity to sell, at any price.


  • That’s not what they were saying, they were saying that it’s not economical to have an abundance of electricity when people need it the least, and little or no electricity when people need it the most. It would be one thing if utilities could sell solar electricity at peak demand hours for a higher price, to make up the difference, but that’s just when solar generation is slowly down significantly or stopped entirely.

    And, yes, I know that battery storage could theoretically solve this, but battery technology is not currently capable of providing electricity for the entirety of the time we need it. New technologies are being developed right now with the goal of achieving long term grid storage, but they are still in the R&D phase. I’m confident a suitable storage technology, or multiple technologies, will eventually come to market, but it’s going to take a while.

    Regardless, it is likely we will always need some kind of on-demand power generation to supplement renewables and maintain grid stability, and I think nuclear is the best option.

    But we shouldn’t act like the problem is that utilities are just greedy. Many utilities aren’t even for-profit companies, as many are either not-for-profit cooperatives or public entities. Sure, there are also many for-profit power utilities as well, maybe even some with connections to the fossil fuel industry, but generally power utilities are not some great villain.



  • I used to advocate for Linux, because I wanted more people to use it, so that more software devs would support it. I care a lot less about that since proton came to prominence. Linux still doesn’t get all the support from devs that I want, but there’s so much great software available now, both open source and proprietary, that I don’t really worry about non Linux users anymore.

    So use whatever OS you want, folks. I don’t really care.




  • One reason the suburbs even exist is that there isn’t space in the city for everyone. Many suburban families would rather live downtown but cannot as they do not have the mega millions to own a 3br condo.

    But I think the reason there isn’t space for everyone in many cities is because a large percentage, or even a majority of the land in many cities is zoned for single family only, even very near downtown areas. I think parking requirements have a lot to do with it as well, since they result in parking lots being built where condos, or other multifamily housing could be built. Theoretically if you get rid of single family only zoning and the parking requirements, more housing units could be built, even larger units, increasing their supply relative to the demand, thus bringing down the per unit price.

    But maybe that theory is flawed. Maybe the problem goes deeper than zoning and parking requirements. A lot of these real estate developments are investments, and investors have an incentive to not build so much housing that the per unit price goes down significantly. Some people might argue that developers and investors could make up for lower per unit prices in volume, but that’s only true if they are large enough and have capital resources to produce at that higher volume, which might be fine for very large developers and investment companies, but not for smaller ones. Plus, large or small, why try to make money selling or renting more units at a lower per unit price when you can make the same amount of money selling or renting fewer units at a higher per unit price?



  • According to Climate Action Tracker, the world is projected to warm between 2.5C and 2.9C, by 2100, based on current pledges and policies.

    According to this New York Times article, mass death of coral reefs is projected to occur at between 1C and 2C of warming, abrupt warming of permafrost is projected to occur at between around 1C and 2.25C of warming, collapse of Greenland ice is projected to occur between 1C and 3C, breakup of West Antarctic ice at between 1C and 3C, sudden shift in the West African monsoon at between about 2C and 3.5C, loss of Amazon rainforest between about 2C and 6C, and shutdown of Atlantic currents at between about 1.5C and 8C.

    The global average temperature has increased 1.17C above the long-term average from 1951 to 1980. That means we are already within the range at which mass death of coral reefs, abrupt warming of permafrost, collapse of Greenland ice, and the breakup of West Antarctic ice could occur.

    People will reflexively reject new and different possibilities when advocates are too radical or aggressive in their approach. That’s why it’s important that we try to win people over using reason and logic, rather than protests. The fact is, cars are an expensive and inefficient means of transporting people and things. That doesn’t mean cars don’t have their use cases. They certainly do, and that’s why I don’t think cars and small trucks will or should go away completely, but in an ideal (ie maximally cost effective and efficient) scenario, cars would represent a relatively small percentage of total conveyance methods.






  • A lot of people who buy trucks these days just need something that can tow a travel trailer or a boat to their favorite camp site a few times a year. It’s not that they need a truck on a day to day basis, but they might need the towing capability on occasion. That’s why these trucks are a weird combination of luxury sedan (with their leather seats and high end interiors) and pickup truck. Most of the time they use it like a regular car, but sometimes they might need the towing capability.
