Why We Should Care About Offshore Wind

The Wind Cries Mary

Posted by dave on October 28, 2023

The gentle breeze on a warm summer day, the gusts that rustle leaves, and the wind that powers turbines - each evokes a sense of nature's force and rhythm. As Jimi Hendrix beautifully encapsulated in his song, "The Wind Cries Mary," the wind has always been an integral part of our world, and its potential is vast.

Residents of Lewes and Rehoboth need no reminder of the changing climate. The imminent threat of sea-level rise paints a clear picture of the impacts our coastal cities will face in the coming decades. Arthur Sowers' recent letter to the Cape Gazette, dated October 20, 2023, titled "New sea-level rise implications for Lewes, Rehoboth" is an eye-opening testament to the urgency of the situation.

This looming threat is not merely a distant prediction; it's a reality marching steadily towards us. While we're slowly progressing towards mitigation, there's still ample opportunity to prevent further damage. Climate change is surfing our way, literally.

Our increasing energy demands are undeniable. And as we navigate this challenging landscape, it's essential to remember that every journey begins with the first step. For us, that step is recognizing and acting upon our energy needs.

Capital investment in renewable energy, especially in our area, is crucial. While the energy requirement is vast, every single watt of renewable energy counts. An "all of the above" energy strategy is indispensable. If there exists a resource that can harness energy, be it from wind, water, or sunlight, it's time we tap into its potential.

Historically, no energy source is free or invisible. However, wind energy comes remarkably close. The Danes, as early as the 1800s, realized the potential of wind and harnessed its power effectively.

Living near the beach, we are privileged to have access to such a phenomenal energy resource. The University of Delaware's Lewes Wind Turbine stands as a testament to the promise of wind energy. It's not just a structure; it's an ode to sustainable future possibilities.

Wind energy offers myriad benefits, and its integration aligns with the best interests of Sussex County residents. Detractors may argue about the potential harm to birds and marine life, but such arguments often lack perspective. Ships, with their unpredictable movements, pose a more significant threat to marine life than stationary turbines. Besides, over millions of years, animals have evolved and adapted to far more significant challenges than wind turbines. Birds survived the dinosaur mass extinction 65 million years ago.

The underlying issue isn't about animal safety but human perception. The crux of the matter is the 'Not In My Back Yard' mentality. It isn't that animals can't see the turbines; it's that humans can. Maybe we should be investigating how to make the turbines blend into the blue sky. Making offshore wind turbines less visible from the shore can be approached in several ways:

Distance

Placing turbines further from shore can significantly reduce their visibility. The farther the distance, the smaller the turbines will appear, eventually blending with the horizon.

Color and Design

Painting turbines a color that matches the sea or sky can help them blend into the background. Additionally, using coatings or designs that reflect the color of the surroundings can also make them less conspicuous.

Lighting

Minimizing lighting on the turbines to what is legally required for safety can reduce their impact on the seascape, especially at night.

Alignment

Carefully planning the layout to align with the natural visual patterns of the sea and horizon can make the turbines less noticeable.

Focal Points

Creating visual distractions or focal points on the shore can draw viewers' eyes away from the turbines. This could include artwork, landscaping, or architectural features.

Reduced Turbine Size

Developing more efficient turbines that can be smaller in size without compromising power output could reduce their visual profile.

Simulations and Visual Impact Assessments

Before installation, conducting thorough visual impact assessments using simulations from various points on the shore can help planners position turbines to minimize visibility.

Mirroring Techniques

Research into materials that could mirror the sea and sky might provide ways to camouflage the turbines effectively.

Holographic Overlays

Implementing technology that could project a view of the sea on the turbine structures, making them appear transparent from certain angles.

Offshore Clustering

Grouping turbines together in designated areas can consolidate the visual impact rather than spreading it across a wider expanse of the viewshed.

Innovative Technologies

Exploring new technologies such as floating platforms could allow turbines to be installed further offshore, where they are less visible.

Policy and Zoning

Governments can implement policies that require a minimum distance from shore for offshore wind farms, reducing their visibility.

Public Education

Educating the public about the benefits of renewable energy and the necessity of wind turbines can also be an effective strategy. When people understand the importance of these structures, they may be less concerned about their visibility.

These methods can be combined for the most effective visual mitigation. However, each approach has trade-offs in terms of cost, efficiency, and environmental impact, and the best solution often depends on the specific circumstances of each wind farm's location.

As we move forward, it's vital to foster an environment that welcomes innovation and investment. When companies with the capital and vision are ready to invest in our future, we should not push them away. Instead, let's entice them with a vision that aligns with our aspirations - a horizon that promises a greener, sustainable future.
