It incentivizes energy innovation but I disagree that it incentivizes, “green” energy.
At the end of the day bitcoin wants the lowest cost, AND most reliable energy.
While the block subsidy is still high the second point is less important. When bitcoin miners make more from the fee market than the subsidy they will care a lot more about the reliability of their energy supply than they do right now because the fee market is less predictable.
The counter to this would be a sustained high fee environment but even still the miners would rather be on than not so the intermittent supply of wind and solar will eventually be out competed by things like hydro, nuclear, nat gas, and anything else that can be always on.
