Where do you live (nearest big city & state) and how tall would you like your evergreen screen to be? Remember that trees don't stop growing at some magical height and pruning a tall hedge to keep it out of the wires will change the look.

Hartford, CT! We’re looking for 10 to 12 feet of height, hi just wish I knew the name of these trees because I thought they looked really nice

They look very much like Thuja 'Green Giant'. But they sure wont stop growing at 10-12'!!

They look more like Leyland Cypress to me. 'Green Giant' has a tighter fuller form. But Leyland, Green Giant, potato, patato, snow load depending. For that look at 10-12', look into the genus Chamaecyparis.
