The increase in land disturbance is a disadvantage of which type of electrical line installation?

The correct response highlights that underground electrical lines typically necessitate more land disturbance compared to overhead installations. This is primarily because the process of installing underground lines involves extensive excavation and trenching. Contractors must dig deep into the ground to lay the cables, which can disrupt soil composition, existing vegetation, and the ecosystem in the surrounding area. This method often requires more planning and considerable effort to manage the environmental impacts effectively.

In contrast, overhead electrical lines require less land disturbance as they are installed on poles above ground. While there is still some impact from the erection of these structures, it generally affects a smaller area and can be less disruptive to the natural habitat than the digging and trenching involved in underground installations.

Understanding these differences is crucial, particularly when evaluating projects for their environmental impact. Thus, the conclusion about underground electrical lines being associated with increased land disturbance is pivotal in discussions surrounding utility installations.
