"They Won't Come Back": Are Taiwan's Offshore Wind Farms Driving Fish Away? | Power To The People

Key Concepts

• Offshore Wind Power: The generation of electricity through wind turbines installed in the ocean.
• Nacelle: The housing at the top of a wind turbine that contains the generator and other critical components.
• Beaufort Scale: An empirical measure that relates wind speed to observed conditions at sea or on land.
• Double-Trawl Fishing: A method where two boats drag a single net between them along the seabed.
• Indo-Pacific Humpback Dolphin: A protected marine mammal species whose habitat overlaps with wind farm development zones.
• Energy Transition: The shift from traditional energy sources to sustainable, renewable alternatives like wind power.

1. The Growth and Mechanics of Offshore Wind

Taiwan has rapidly expanded its offshore wind capacity, growing from near-zero in 2014 to 3.2 gigawatts by August 2025, ranking fifth globally in growth rate.

• Technical Operation: Wind turbines function by capturing wind energy via blades, which drive a generator housed in the nacelle. The energy is then processed through a transformer located at the base of the structure.
• Industry Requirements: The sector demands a diverse workforce, including civil and electrical engineers, financial/legal experts, and specialized technicians. Essential physical requirements for offshore workers include high stamina, comfort with heights, and immunity to seasickness.

2. Impact on Fisheries and Marine Ecosystems

The development of wind farms has created a significant conflict between green energy infrastructure and traditional fishing livelihoods.

• Fishermen’s Concerns: Fishermen in Changhua report that wind turbines act as physical obstacles that snag nets and restrict access to traditional fishing grounds. Vibrations and changes in water currents caused by turbine foundations are believed to deter fish, particularly during shrimp season.
• Ecological Perspective: While some argue that turbine foundations create artificial reefs that attract species like octopus and groupers, environmentalists remain concerned about the Indo-Pacific humpback dolphin. Regulations mandate that piling work must cease if mammals are spotted within 750 meters of a site.
• Economic Adaptation: Some fishing families have transitioned from nearshore trawling to offshore support work. This requires upgrading to larger, specialized vessels equipped with safety features like watertight doors and the ability to withstand high winds (up to Beaufort scale 9).

3. Training and Safety Frameworks

To support the industry, specialized training centers like the Taiwan Wind Energy Training Company have been established.

• Methodology: Training involves high-fidelity simulations of offshore environments, including ladder climbing, emergency evacuation, and first-aid procedures for injured technicians at height.
• Risk Mitigation: Because offshore medical assistance is not immediately available, the industry prioritizes "preventive maintenance" and rigorous safety protocols to minimize the risk of accidents.

4. Key Arguments and Perspectives

• The Pro-Development Stance: Proponents argue that wind power is essential for carbon reduction and that marine life can adapt to the presence of turbines. They emphasize that the energy transition is a necessary reality for future generations.
• The Fishermen’s Stance: Fishermen argue that the government has failed to provide adequate support or compensation for the loss of fishing grounds, leaving them in a state of uncertainty regarding their long-term survival.
• The Media’s Role: Organizations like the Taiwan Renewable Energy Promotion Alliance emphasize the importance of acting as a "green energy media platform" to combat misinformation and explain complex technical topics to the public.

5. Notable Quotes

• "If our wind power or our electricity infrastructure isn’t adequately developed then we also have to face the consequences of that reality." — Perspective on the necessity of infrastructure development.
• "Creating fake news can take just a minute... but explaining accurate information clearly can take days." — On the challenges of public communication regarding energy policy.

6. Synthesis and Conclusion

The transition to offshore wind in Taiwan represents a complex intersection of technological advancement, economic disruption, and environmental stewardship. While the industry offers significant growth and sustainable energy benefits, it has created profound challenges for the fishing community, whose traditional livelihoods are being squeezed by restricted access and changing marine conditions. The long-term success of this transition depends on balancing the urgent need for renewable energy with the socio-economic protection of local stakeholders and the preservation of marine biodiversity. Actionable progress is currently being sought through better public education, specialized workforce training, and the adaptation of fishing vessels to serve the new energy economy.
