While highly efficient, overhead lines do have disadvantages and are subject to specific environmental and community considerations:

• Vulnerability to External Factors: They are exposed to the elements and can be damaged by severe weather, such as high winds, lightning strikes, or heavy ice and snow. They are also susceptible to damage from falling trees or wildlife, which can lead to service disruptions.

• Visual and Landscape Impact: The presence of large towers and conductors can be visually intrusive and disrupt the aesthetic of natural landscapes and urban areas. This is a common concern in community planning and is addressed by best practices like the "Holford Rules" for strategic routing.

• Land Use: overhead lines require a significant right-of-way corridor, which can impact land use for agriculture, development, and other purposes.

• Safety Risks: Although modern standards and safety measures are in place, overhead lines pose a potential safety risk, particularly with respect to accidental contact, and require strict adherence to safety protocols during construction and maintenance.
