If I'm gonna be entirely honest, I think power lines are really nice looking. I even have them as my phones wallpaper. Maybe it's just because I have a interest in infrastructure or something, idk
I know it's a very unpopular opinion but I actually like the aesthetics of infrastructure and industry.
When I see a steel mill, an oil rig or powerplants like wind parks, hydro- or nuclear power I am reminded of the human ingenuity that went into it. How many people needed to band together to work on something bigger than their tribe. I am reminded of our awe inspiring power to shape our environment completely.
I actually kind of enjoy powerlines and junction boxes. There's a level of engineering that is both rough and delicate that is magnified by how orderly and chaotic they are alike.
Now if the power lines are at the expense of a view through trees, that'd be more a bummer. Likewise if the trees remain that's a hazard waiting to happen, which is also a bummer.
Buried lines and conduit pipe are preferable in most cases and share similar aesthetic characteristics.
I think clean power lines look nice. I'd definitely prefer them to a butterfly killing roadway or lighted poles that create light pollution and confuse wildlife.
Power and telecom lines are one of the more organic and chaotic parts of an urban environment. I live somewhere that has loads of them, including trollycar lines. In some places it's pretty thick.
I love it. It adds a layer of aesthetic that prevents the world from looking too minimalist, which is nice since that's where most new architecture is headed...
