Not too sure why this comment got downvoted.

Grid balancing is no joke - you’ll likely have new nuclear up and running before you rebuild the grid of an entire nation (which is needed for renewables to take the lead).

Let’s not forget, lithium for batteries, a key element in a renewable grid (to help offload and balance) is also not widely produced in Europe. Water batteries could work, but those are not small projects.

Nuclear is your “short” term because renewables (grid rebuild) are still a long term project.
