I also note that he doesn't even attempt to quantify how much was spent on hydrocarbons in the same time frame (as far as I can tell, investment in oil and gas was at least 2x in renewables in 2019, and I suspect that multiple would get a lot higher further back), and that the timeframe chosen is quite long to spread out the recent gains in renewables over as long a time as possible while giving hydrocarbons longer to stack up an increase.

When you say "as far as I can tell", what do you mean? Why do you say 2x?

This was based on some googling for reports with some numbers. I can't find the exact one I used to get the number but the report linked by ahelwer in another commend has the same kind of numbers (investment in hydrocarbons was 2.6x of renewable generation: adding on top investments in switching demand to be able to use renewables, which is primarily investment in EVs, puts the number at 1.7x in 2019): https://about.bnef.com/energy-transition-investment/ https://imgur.com/B2QBY6u
