The main arguments against the construction of new power lines are the destruction of the landscape and health hazards. The large north-south HVDC lines planned in Germany are partially being laid as underground cables. This is an optimal solution in terms of space requirements, landscape views, and pollution due to electromagnetic fields. However, the costs for underground cables are three to ten times higher than for overhead power transmission lines.
