Long-term, that's the smart and also necessary move. But it can't be done overnight, and the transition has its significant challenges. I hope they don't mess it up it and will address these problems rationally - but given how most EU leaders have acted over these past few years, I remain painfully unconvinced that they will.
Isn't solar the fastest energy source to spin up? Just take them out of the crate, put them on racks, tie them to the grid.
Also, "the grid" cannot absorb any amount of solar energy - so if you choose to address (at least parts) of the above challenge with a photovoltaic build-out that results in massive excess capacity during summer, there needs to be a plan (and again, its implementation) to handle that.
