Who Experiences the wave energy impact on marine biodiversity?

Everyone from coastal fishermen to marine biologists is affected by this. Coastal communities like those in Portugal rely heavily on fishing, and changes in fish populations due to wave power installations can seriously impact livelihoods. For example, in the Azores, small-scale fishermen have reported shifts in the behavior of key fish species, possibly linked to nearby wave energy converters. 🐟 On the other hand, scientists studying the coast of Scotland noticed that some marine animals use wave farms as artificial reefs, which can increase biodiversity by creating new habitats.

What Are the marine biodiversity risks from wave power?

While wave energy promises green power, it is not free from risks. Let’s look at the key marine biodiversity risks from wave power along with specific examples to question common assumptions:

⚠️
• Habitat Disruption: Wave energy devices may disrupt seafloor habitats, similar to how construction noise disturbs a neighborhood.
• Noise Pollution: Marine mammals like dolphins rely on acoustic signals. In California, increasing underwater noise from wave turbines has interfered with their communication.
• Collision Risks: Animals such as sea turtles face collision risks with moving parts, somewhat like birds flying into wind turbines on land.
• Altered Water Flow: Wave farms can modify local currents. Studies in Denmark showed changes in sediment transport nearby wave energy parks.
• Electromagnetic Fields: Cables transmitting electricity can affect species sensitive to magnetic fields - a phenomenon seen with some sharks and rays.
• Species Displacement: Certain fish species might avoid areas around wave energy installations, threatening local ecosystem dynamics.
• Accumulation of Pollutants: Structures can attract debris, potentially increasing pollution hotspots if not managed properly.

To offer perspective, here is a comparison of these risks with the benefits of wave energy for marine environments:
