Offshore Wind Power Generation

Common Types of Fixed Subsea Structures for Offshore Wind Turbines

Pros for the Offshore Wind Power Generation

1. More Energy Get Produce

Offshore wind speeds are faster than on land, leading to greater energy production with small increases in wind speed. This means offshore wind farms can generate significantly more energy. 

2. Steadier Than Onshore Wind Farms

Offshore wind speeds are typically more consistent compared to onshore locations. This steadier supply of wind translates to a more reliable source of energy. 

3. Meet High Electricity Demand 

Coastal areas have high energy demands, with a significant population residing in major coastal cities. Offshore wind farms in these areas can meet nearby communities' energy needs by utilizing local energy sources. 

4. Also Having the Advantages of Onshore Wind Farms

Offshore wind farms share the advantages of land-based wind farms: renewable energy, water-free operation, domestic energy source, job creation, and minimal environmental pollution and greenhouse gas emissions. 

5. Economic Impacts 

The US government plans to deploy 30 gigawatts of offshore wind energy by 2030, creating 77,000 jobs, powering 10 million homes, and reducing 78 million metric tons of carbon emissions. Over $300 million has been allocated for offshore wind research and development projects since 2011. 

 Cons for the Offshore Wind Power Generation

1. The Transport of Energy is Expensive

The production and installation of power cables beneath the seafloor for transmitting electricity back to land can incur significant expenses. 

2. Difficult to Built 

Building wind farms in water deeper than 200 feet (~60 m) is challenging. While the east coast of the U.S. has relatively shallow waters, most of the wind energy resources off the west coast are in deeper waters. Floating wind turbines are helping overcome this obstacle. 

3. Strong Waves and Strong Wind Can Damage the Wind Farms

Wind turbines are susceptible to damage from wave action and high winds, particularly during severe storms or hurricanes. 

4. Effect Landscape

Offshore wind farms located within sight of the coastline, with a distance of up to 26 miles offshore (depending on viewing conditions), might face opposition from local residents and potentially impact tourism and property values. 

Conclusion

Offshore wind energy is a promising solution to meet coastal areas' increasing energy demands while reducing reliance on non-renewable energy sources. Despite some challenges, offshore wind energy offers faster and steadier wind speeds, local energy sourcing, and minimal greenhouse gas emissions. With government support and ongoing research, offshore wind energy has the potential to play a significant role in achieving a cleaner and more sustainable energy future.
