#2Asking as an ill-informed European.
Is this the Koch of the Koch Brothers that I only know as the financiers behind the GOP and climate denialism and bankrolling efforts to gut environmental protection laws?

#3Seems like they installed variable frequency drives (their "algorithm) on their motors; nothing more.

Yes.

#6The Koch brothers hired private investigators to trail, intimidate, and attempt to get dirt on Jane Mayer when she was writing Dark Money -- a book about how they covertly funded ultra-right wingers and climate sceptics to protect their hundreds of billions of dollars of oil investments. Charles Koch literally shoulders a non-trivial amount of responsibility for a possible coming semi-apocalypse, and he makes plenty of movie villains look laughably tame in comparison.
But this is a good step.

1/3 reduction is 1/3 reduction. It's worth doing, even if how they did it is no great breakthrough.

#8Worth pointing out that due to their efficiency, what this has to be about is not making the motors more efficient, but reducing the power output, e.g. by making the driven mechanical load more efficient.
Edit: Skimming the article makes it sound like they switched from U/f control to vector control.

#10Reducing per unit energy consumption (aka increasing energy efficiency) is not only very different from reducing global energy consumption, but it can often lead to an increase in global energy consumption. This is called Jevons paradox: https://en.wikipedia.org/wiki/Jevons_paradox and is quite an interesting topic.
