I'm sure you'd know better than I would. I guess it would have to be all of mainland Europe than.
Do you work for the power company in Denmark? You seem to know a lot about "current" events! (Sorry, I couldn't help myself!)

Different Subject:
Aluding to what I said earlier, that's one of the reasons Hammond Organs have to be modified if brought from the States to Europe and visa versa.
Their "Tonewheel Generators" (3 1/2 foot rods with tonewheels attached, which give the organ its tones) rotate at a set speed (1200 RPM @ 60 Hz U.S.) and that insures that "A natural" above "middle C" stays tuned at a perfect 440 Hz. If a U.S. Hammond is brought to Europe and forced to run at 50 Hz, then the tonewheel generator spins at only 1000 RPM, and hence, throws the tuning down a pitch and a half (approx.)
The opposite is of course true if a European Hammond is brought to the US, but then again the shape of the plugs into the wall are going to be different, so my point is more theoretical than it is practical anyway.

I don't work for them. I was "forced" to learn about it, during my education as a marine engineer. Quite interresting in fact. Recently we had a blackout in a part of Denmark (Sealand). The reason was a short circuit in Sweden! The short circuit took out a nuclear powerplant. 5 minuttes later another short circuit (also in Sweden happend) and took out another nuclear powerplant. Blackout was the result. (We do have some parts only connected to the rest of Europe via DC lines, which was a reason for the rest of Europe unable to back up Sealand.)
Another time a Nuclear Powerplant in France jumped of the grid, and that could be seen on the frequency in the rest of Europe.
I did make an error, Europe is divided into 2 Powergrids (I don't know about former/present eastern Europe. But we do have 400kV AC lines going from northen Denmark to Southern Italy.

(Rant-warning.)
It's likely to have an opposite effect. Learning "the tools of the trade" makes you better, which opens up possibilites and makes it more fun.
If you had a choice between a self-made plumber who hadn't properly learned his job because "if I did, it would make my work boring", and a professional plumber who'd gone to plumbing-school (or whereber plumbers go) and properly learned his trade. Who do you think does the best job? And, who do you think is more likely to enjoy his work?
