I think you missed my point: There is no headwind - the net is positive.

That is to say, renewables are increasing, therefore the net velocity is positive (and accelerating). It is not 100%, so we have further to go (distance traveled).

If you want to measure the rate of change, it makes sense to benchmark against where you started and see if you are progressing.

In terms of renewable power adoption, the world is making ground, not losing it. The world on a better trajectory than it was 20 years ago, a wouldn't without the effort put in over the last few decades. There is a lot more work to do, and it is not going as fast as one might hope, but that does not negate past accomplishments.
