Offshore wind farms could wirelessly charge electric ships, but may drive away animals

Offshore wind farms are expanding, and their effects on marine ecosystems are being studied. Early research showed harbour porpoises avoided wind farm sites, reducing their activity. Later studies indicated a gradual increase in porpoise presence, possibly due to habituation or food availability. New computer simulations suggest construction alone did not cause significant porpoise displacement. Scientists continue to examine underwater noise, vessel traffic, and habitat changes for long-term impacts.
