Offshore Wind Power’s Impact on Sea Surface Temperatures
Recent research indicates that offshore wind energy might be contributing to rising sea surface temperatures along the East Coast. Still, advocates are promoting this energy source as essential for clean energy initiatives, often overlooking potential environmental ramifications.
A study published on November 5, which underwent peer review, was conducted by Hyodae Seo, César Sauvage, Christoph Renkl, Julie K. Lundquist, and Anthony Kirincich, with funding from the Department of Energy. This research utilized model simulations revealing that “the cumulative reduction in wind stress from extensive wind farm clusters results in an increase of sea surface temperatures between 0.3 and 0.4 degrees Celsius and leads to shallower mixed layers.” The study focused on data from 2017 to 2021, noting that offshore wind lease areas in Massachusetts, Rhode Island, and New Jersey showed slight warming under specific seasonal tendencies.
While the temperature increase is minor, some experts in the energy sector told the Daily Caller News Foundation that these findings underline the broader environmental impact of energy sources, which is often ignored when policies are formulated solely through an emissions-centric lens.
“The data shows that the reduction in wind stress due to large wind farm clusters increases sea temperatures by 0.3 to 0.4 degrees Celsius, which shallows the mixed layer,” the researchers observed. “In the model we used, increases in sea surface temperatures around offshore wind farms were connected to decreased wind stress and turbulent mixing in the ocean’s upper layers. Though this warming is modest relative to the annual sea surface temperature variation (ranging from 7 to 25 degrees Celsius) in the mid-Atlantic Gulf, it significantly influences interannual shifts in summer sea surface temperatures observed on the U.S. East Coast’s outer continental shelf.”
The specific models mentioned were the Weather Research and Forecasting (WRF) model, the Regional Ocean Modeling System, and WaveWatch III.
The research articulated that “our findings suggest sea surface temperature rises could outpace air temperature increases at depths of around 2 meters, leading to greater heat fluxes from the ocean into the atmosphere which might create a more unstable atmospheric boundary layer.” The warmer surface and increased stratification patterns correlate with diminished wind stress and turbulent mixing, underscoring the connection between wind farms and higher sea temperatures.
Energy policy experts comment that the study reflects an ironic impact of wind power, with potential environmental issues being mirrored in energy policies. Previously noted harm to wildlife arising from “clean” energy technologies further complicates this narrative.
“Wind turbines might be classified in various ways, but labeling them as ‘clean’ or ‘green’ shouldn’t be an option. Ironically, solutions designed to combat global warming might actually contribute to further warming,” remarked Mark Morano, publisher of ClimateDepot.com. “This study reinforces concerns regarding the negative consequences associated with offshore wind power. Earlier data suggested that offshore wind adversely affects marine mammals, and now we see this study adding to understanding by indicating that offshore wind is a contributor to warming.”
The paper mentions in simulations that warmer conditions were prevalent in New Jersey, demonstrating a stronger warming trend in years 2017, 2019, and 2021, while the years 2018 and 2020 showed less warming. A parallel temperature increase pattern has also been noted in simulations along California’s coast linked to floating offshore wind technology.
“This study adds further concern to what we’ve been warning about for some time,” said Dustin Delano, president of the New England Fisheries Management Association (NEFSA). “We believe that there’s a critical need for comprehensive research on the consequences of offshore wind energy projects. Our own investigations indicate that electromagnetic fields emanating from underwater power cables have a detrimental effect on lobster larvae, seriously threatening both lobster populations and the coastal communities that rely on them. The contradiction is evident: the very technologies being pushed as climate solutions disrupt industries and introduce new environmental challenges.”
Steve Milloy, a senior research fellow at the Energy and Environmental Law Institute, commented that “this finding isn’t surprising. Prior studies from Germany illustrated a link between wind turbines and dryer soil downwind. Moreover, offshore wind turbines have been known to threaten migratory birds and harm marine ecosystems while generating electricity that is often inefficient and costly.”
Former President Joe Biden promoted significant offshore wind developments and changes in regulations as part of the climate agenda. In contrast, the previous Trump administration restricted offshore projects and reduced funding in favor of energy solutions deemed more dependable.
It is noteworthy that the National Oceanic and Atmospheric Administration (NOAA) previously informed DCNF that the current administration bypassed environmental assessments to expedite offshore wind ventures.
“Records indicating NOAA scientists’ insights show that recent actions from the Biden administration overlooked guidelines meant to protect ecosystems. They have approved these projects without fully considering their negative environmental impacts,” a NOAA representative noted. “These actions clearly disregard decades of rigorous scientific evidence and approaches developed to ensure environmental safety in offshore wind projects.”
