No, not everywhere. Most of NYC uses underground wires. My neighborhood in Colorado near Boulder built in the 60s uses underground wires as well.

- mschuster91 8y agoUnderground wiring is far more efficient in big cities, as the major cost part is "miles of trench digged" and in a city the ratio of "customers per mile" is waaaay higer than in rural areas, thus reducing "investment per customer". In addition this wiring is at the maximum 110 kV, you do NOT want a 380 kV feed in a major city. These things require a shitload of clearance, talk about 40m wide and 4m deep trenches!
