If you have the Alps on your doorstep, you may simply want your landscape to stay the way it is, neither adding (modern) sculptures nor (overground) power cables.
Think of the Sierra Club.
The litmus test for all "oh noes! Don't put any engineering into our pretty mountains!" should always be a proposal to dismantle the Karprun reservoirs, the Landwasser viaduct and the Stelvio hairpins. Because visible engineering is bad, right?
The Alps are mostly impacted. Once you reach the mountains in Germany there aren't many consumers of electricity left requiring new power lines.
The big new power lines are needed to get electricity from offshore Windparks in the Northern and Baltic Sea to industrial zones south. The conflicts are with villagers in probably nice but not as special areas as the Alps.
I think this is one of many times it's not possible for everything to stay the same. If everyone fights and delays switch away from fossil fuels, the landscape will change in one way. If these lines are run, it will change in another. I have my opinions about which a true nature lover would prefer.
