Electrons themselves barely move! On the order of meters per week in a reasonable DC circuit and hardly wiggle in AC. Electric fields traveling at ~light speed, directed by, but not in, wires, deliver energy. Pretty weird.

Fair!

I would not be surprised if the pm effects are > change in traffic volumes because moving diesel trucks and busses from full stop over and over is real bad.

You have me convinced my prior should have low prob of PM effects >2x the change in traffic. And the method for the CI is sus.

But parallel trends with other cities is violated for the reasons you mention (w-fire smoke, elec. gen) and they imply (local wind direction). Sometimes you just can't DiD.

The way back machine is great, but maybe it’s time to make forks and wikis of these sites e.g. @audreyt.org

you could call this take “don’t think of a framed elephant“

Also a bummer that higher ethanol blends appear to increase local ozone pollution. www.journals.uchicago.edu/doi/abs/10.1...

Should have been Fig 1.

3. Fixed MERs ignore time of day and year, which are really important for variable renewables (because substitution effects)

4. The marginal effect of a particular technology or action under a binding carbon cap is always zero (because substitution effects)

Here is the tl;dr of our 4 main points about quantifying emissions effects:

1. MERs don't make sense for non-marginal changes

2. UNFCCC includes guidance and weights for operating margin and build margin--the build margin is probably much larger especially in places with lots of renewables

Nice! Would be cool to see the margin difference on the vertical axis in the second fig.
