Thx for your article. However I have to say that I do not agree to your conclusion regarding power demand.
Firstly I believe the blockchain technology has to evolve to a much lower energy consumption to really get hold on every day transactions. Proof of stake is IMHO one of the most promising options atm.
Secondly I fear more energy consumption will not drag more investments into renewable energy... for crypto mining you need 24/7 constant base load power. By renewables this can only be provided by combining Solar or Wind with battery systems. (Hydro capacity is exhausted at most places) what increases power prices. This combination can not compete with a chinese coal power plant for the next 5 years. (after that likely it will but there is abundant world energy demand to be fed before we have any spare power left)
And do not forget the grey energy that is needed to build the ASIC and GPU chips mainly produced in Asia...
So IMHO blockchain is still juvenile.. but growing up and getting more mainstream power consumption could be a serious hurdle going forward and has to be taken care of.

Big Earth Batteries? wind and solar are not so efficient anymore :)
Big Earth Batteries is a very interesting technology... but why do you conclude that wind and solar are not so efficient anymore?
Well it depends where you are in the world,if its sunny then great for solar but mosttimes in europe its unreliable,unless you spend megabucks on solar panels :) and big batterys :)
And wind is ok but i know that windturbines (the huge ones) need a huge amount of maintaince cost alot of money. I guess if you have a small windmill thats great,or like my friend made a spiral one that spun with hardly any wind, but you still need a battery 😂 i just got into the earth and saltwater battery thingy,its appealing because there is no actuall battery hahaha
