We definitely do need some amount of conventional inertia. I agree that alternative sources are probably ideal. Doesn't really matter what kind of prime mover is involved. Wind/solar augmented with big chunks of iron spinning in sync with the grid would easily mitigate whatever scare language is involved with inertia. Note that this is not about longer term energy storage, so the overall generation mix conversation is still very hot.
