Misalignment of objectives of commercial agents and commercial and society is an economic problem?

 By Ian Page I commented recently that something seems wrong with economics or its application as it doesn't seem to be able to effectively capture the external costs of production and use to society in a way that actually drives commercial actors to make decisions that are right for society at large.

EV S curves good news

 by Ian Page The right hand chart is interesting as it predicts the time from 10% evs to 85% as about 8 years.Given the percentages currently on the left chart moat having passed 10% by 2020, it is plausible that 2028 will see the beginning of the end of the  transition.

RMI X change report on exponential EV adoption

 By Ian Page. https://rmi.org/insight/x-change-cars/ you can get it from here. Also the electricity one... https://rmi.org/insight/x-change-electricity/ ( Apparently, there is a whole set of X Change reports funded by Besos, taking an exponential approach rather than the usual linear  approach that  underestimates change.)

A thought piece

By Ian Page. Most papers and reports on the renewable transition have a particular unstated mindset.  It is assumed that the transition involves replacing  fossils with renewable electricity in all its forms and worries about the effect of variability, the techno economics of various storage and CO2 capture and use scenarios, effects on transmission and transport, and so on. This all looks pretty reasonable and is described in the first diagram, Once the inflection point is reached, the motivation to build new more efficient factories producing renewable generators decreases as they need a large sales volume to repay the investment and the opportunity space is decreasing  Thus the saturation point becomes a self-fulfilling prophecy, An alternative mindset is shown in the second diagram Instead of stopping new manufacturing capacity, it's possible that the cost of manufacturing and install...
