@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green Dude, you’re just trolling at this point. You can’t use the reality of the current system to argue that the system can’t be changed to operate differently. Internalize the externalities then change will happen quickly. I’ve explained what I think the logical flaws are in your statements, now it’s time to move on. Good day.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green And of course we’re seeing very rapid growth in renewable power generation + battery storage, doubling every 2-3 years, in part because it’s cheaper even in direct costs terms than alternatives. Because of learning effects, that cost advantage will only increase over time.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green I would add that current measures of economic activity only imperfectly capture the externalities associated with pollution, so the GDP growth that you now see is partly the result of ignoring real costs of fossil pollution.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green Finally, embedded emissions for manufactured products are almost always small compared to direct emissions from their use, even for products created in the current system.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green There are some embedded emissions from creating certain materials (e.g. aluminum, cement, steel) but in each case there are ways to produce these materials without those process emissions.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green No, H2 is problematic for many reasons. Even if generated from electrolysis, H2 itself is an indirect GHG.

In any case, the idea that embedded emissions are a transient phenomenon follows from that fact that almost all embedded emissions come from energy use, and in a zero emissions system, that energy use would have zero emissions.

@jackofalltrades @coffee2Di4 @urlyman @FantasticalEconomics @ajsadauskas @green People with houses and EVs powered by solar PVs + batteries is the simplest example. The embedded emissions are a transient phenomenon, once we’ve decarbonized supply chains that issue will be solved.

@coffee2Di4 @jackofalltrades @urlyman @FantasticalEconomics @ajsadauskas @green PS. Anyone talking about this issue needs to distinguish between absolute decoupling of ENERGY USE from economic activity and absolute decoupling of EMISSIONS from economic activity. Achieving the latter is much easier than the former, given the many ways to power modern tech with zero emissions, but people often conflate the two.
