In my thread on their article in the Hindu, I wrongly concluded that @KanitkarT and @tjayaraman had got India's and world per capita emissions wrong, as I didn't spot that they used tons C not tons CO2.
I've taken that tweet down and I'm sorry.
2/8
In my defense, no units were mentioned only 'emissions', and tons C is an odd unit to use in a newspaper article.
Adding units would have been good.
I think the rest of @KanitkarT responses to me miss the point. I'll respond to that here again.

On Germany, I was responding using it as a counterexample to a very specific claim in your piece, which you have sidestepped in your response to me.
You state "renewables at best can meet residential consumption and some part of the demand from the service sector".
4/8
This statement's inconsistent with the literature on grid integration of renewables and real-world experience. It's perfectly possible to power grids with large shares of variable renewables, certainly larger than India's 7% today.

Secondly, on innovation you made a very specific claim that green innovation has slowed down since the Copenhagen accord moved away from legally binding commitments.
You respond not on this claim, but by saying that at best battery technology is 5 Rs/kWh.
6/8
Your support for this claim in the article is vague numbers on global patenting falling 30 - 50% between 2009-10 to 2017.
You do not engage at all with what we know about technology cost curves for wind, solar, batteries, electrolyzers, energy efficient LEDS, etc

I am also having real trouble replicating your claim that "Annual filing of patents shows a marked decline, ranging between 30% to 50% or more from 2009-10 to 2017, across all subsectors and across all developed countries, without exception."
7/8
According to my calculations, annual patenting rose in all but 4 OECD countries from the 2009-10 average (you say 2009-10, I take the average) to 2017.
See below.
What's your source & calculation for this claim?
