  • Great point. You need concrete for wind, solar, and li-ion battery storage too (including pumped hydro), but out of those I’d say pumped hydro is the only one that remotely compares in the amount of concrete needed for construction.

    So purely looking at the emissions from materials needed to build these power sources, renewables have the edge due to less concrete. These emissions might show up elsewhere in raw material extraction like with silicon for solar, and then the rare earth metals needed for generators in wind, all the lithium/nickel/cobalt needed for batteries, etc., but I want to say that the Life Cycle Assessments (LCAs) from places like the National Renewable Energy Laboratory (NREL) in the US or the International Energy Agency (IEA) worldwide have taken that into account and still show that renewables + storage are cheaper on a carbon basis compared to fossil fuels and nuclear.


  • Did you read the quote? 15-20 years, as in decades before 1 nuke plant is built. I agree in that politicians of the past should have led us to a more sustainable and resilient energy future, but we’re here now.

    Advanced nuclear should still be 100% pursued to try to get those lead times down and to incorporate things like waste recycling, modularity, etc., but the lead time in decades absolutely means nuclear power might not be something worth doing.

    The IPCC puts the next 10-20 years as the most important and perilous for getting a hold on climate change. If we wait for that long by not rolling out emission-free power sources, transit modes, or even carbon-free concrete, etc., then we might cross planetary boundaries that we can’t come back from.

    Nuclear is a safe bet and bet worth pursuing. I would argue that, along with that source from the IAEA, old nuclear is note worth it.


  • It all depends on the cost of living relative to the wages accrued. Often wages haven’t kept up with the cost of living, so people feel more and more that the deal with their employers gets worse and worse. Someone earning 200k/year might be living the same as someone working 60k/year depending on where those people live

    Now, there is something to be said about why cost of living should vary from place to place. Part of it is scarcity of habitation: if there aren’t very many available flats or lots, there might be fierce competition for people to fill what flats or lots do become available. Supply and demand.

    Other aspects might be debt accrued by businesses that they pass on to their customers, externalities like wars or laws, etc.

    I also want to point out that a lot of people associate more wealth with more consumption, so you might see people rise to spend all of the new resources they accumulate rather than securitizing and saving that wealth for unforeseen events. Lots of people consume at terribly non-sustainable rates, and there should be conversations about what effects behaviors can have on the world, outside of the economy.


  • There was a phenomenon in the US labor market during 2022/2023 called “quiet quitting” where laborers across the market realized that companies weren’t paying wages adequately or to a level that reflected the kind of work laborers would perform.

    It was thought that companies paid their workers short of what the workers are owed, and in response to that, a large number of people, many trending young, started behaving according to those wages.

    This often meant reducing work speed or efficiency, reducing communication, etc. Laborers would claim that they were doing the bare minimum to match their wage compensation.

    The other side of this is that the US labor market at that time favored laborers over companies. Workers had more leverage about getting job offers and negotiating terms than companies had, partly due to a rebound from COVID.

    This meant that there wasn’t as much of an anxiety of workers being fired from their position since they would find it easy to get another job. So people did look for other jobs, often while working, to see if they might improve their circumstances and land a job that pays better.

    The “quiet” part was about sliding back on performance or even job tasks themselves, and the “quitting” part was about workers possibly leaving companies for other offers.

    I might have conflated The Great Resignation with this, but both phenomena affect the other.
