If, like me, you toss and turn of an evening wondering what the solar PV cost curve fit would look like if it was weighted by production, wonder no more.
It doesn't make much sense to equally weight production of a few MW of solar in the 1970s, given that the major cost drivers today are occurring on 500 GW/year scale, so I reweighted the curve accordingly. What we see is that the solar cost curve is more like 44% than the usually quoted 25-30%, mostly as a result of finding product-market fit in the last decade.
What is means is that for every doubling of cumulative production, cost declines by 44%! Currently, we're doubling roughly every 2 years.

@paulbettner Can we take some consolation from the fact that the 25 years didn't actually make much progress because USA USA USA!? :-/

@burnrevolt What is, then, the empirical evidence that degrowth is viable?

@tomaspueyo @akin__akintola @Jameskbest1Best I can't think of any either, but focusing your search on countries that went from extremely high income/wealth inequality to lower GINI scores might yield some leads.

@akin__akintola @Jameskbest1Best Unless you do degrowth accounting (imperial splits taking GDP out of the picture) GDP and GDP per capita kept growing during decolonization

@DrEricDing Renters not being able to buy INCREASES inventory.
Owners not wanting to sell because of high rates is a wash, because they would have sold one and bought another, no net change in inventory.
Still not a good situation, but I think you have some of the causes wrong.

More worries—Mortgage payments now at an all time high. This leads to many problems— 1) countless renters can't afford to buy, 2) countless owners can’t afford to sell because they can’t afford a new mortgage payment elsewhere. 3) Low home inventory as result causes more issues. 4) WORSE➡️Many mortgage lenders & banks stuck holding mortgage-backed securities of homes with very low interest rate returns, much lower than current market interest rates—so low that if there is a liquidity crunch, such banks can’t easily offload undermarket-return mortgages/MBS on the open market—akin to SVB stuck with very low interest Treasury bonds they couldn’t quickly sell==>led to their collapse with any whiff of instability. All it would take to topple the housing/MBS market is a small recession to set off a chain reaction. 🏠bubble & 🏦🌀?

@inkandsinewaves While the others were throwing their harpoons, you dove in, using it as a pike. They even named a dive after that move. And the market, of course.

@inkandsinewaves I'll never forget your role in slaying the beast. They even named a hockey team after it.

NEW: I’m not sure people fully appreciate how dire the US life expectancy / mortality situation has got.
My column: enterprise-sharing.ft.com/redeem/75e5e3d…
And some utterly damning charts.
1) at *every* point on the income distribution, Americans live shorter lives than the English.
