Habitat Change

Habitat Change

The introduction of wind or marine renewable energy devices to the environment can change the physical habitat. The development of land-based wind farms, for example, typically requires the addition of roads and infrastructure, which can lead to habitat degradation and/or fragmentation. Installation of offshore wind and marine renewable energy devices' associated subsea power cables will likely result in changes to seafloor habitats. The physical presence of one or many devices may cause animals to avoid the area, potentially resulting in loss of foraging, breeding, rearing, or resting habitats. Fish may be attracted to a device to feed on algae or to swim in an eddy, while bats may be attracted to a device to feed on insects that are attracted by the light, both of which may place them at higher risk for collision with dynamic portions of the device. Mooring lines that anchor floating devices to the seafloor could also confuse or entrap large marine animals like whales, causing panic and potential injury or increased predation.
