Offshore wind power in the United States is in the early stages of development. In 2022, the National Renewable Energy Laboratory (NREL) estimated that the country has a "technical" resource potential of 1,476 GW (fixed-bottom) and 2,773 GW (floating) offshore wind power.{{cite web |last=Lopez |first=Anthony |last2=Green |first2=Rebecca |last3=Williams |first3=Travis |last4=Lantz |first4=Eric |last5=Buster |first5=Grant |last6=Roberts |first6=Billy |date=August 15, 2022 |title=Offshore Wind Energy Technical Potential for the Contiguous United States |url=https://www.nrel.gov/docs/fy22osti/83650.pdf |access-date=November 4, 2024 |work=National Renewable Energy Laboratory}} Offshore wind projects are currently being developed along the East Coast, in the Great Lakes, and on the Pacific Coast, with a focus on areas with high wind potential.

History and background
Offshore wind power in the United States began to develop in the early 2000s. The Cape Wind project, proposed for Nantucket Sound in Massachusetts, was the first significant offshore wind project attempted in the U.S. However, it faced numerous challenges, including legal disputes, opposition from local communities, and environmental concerns, and was eventually canceled in 2017.{{Cite web |date=October 19, 2007 |title=Cape Cod Commission Denies Cape Wind Application |url=https://www.reuters.com/article/business/environment/cape-cod-commission-denies-cape-wind-application-idUSN19302896/ |url-status=live |access-date=March 5, 2025 |website=Reuters}}
The first operational offshore wind farm in the U.S., Block Island Wind Farm, was completed in 2016 off the coast of Rhode Island. It consists of five turbines and has a capacity of 30 MW.{{Cite web |title=Offshore Wind Arrives in America |url=https://www.energy.gov/articles/offshore-wind-arrives-america |access-date=2025-03-06 |website=Energy.gov}}
In the following years, states along the East Coast, including Massachusetts, New Jersey, and New York, began to set renewable energy targets that included offshore wind, creating a market for new projects. In 2021, the Biden administration announced its goal of installing 30 gigawatts of offshore wind power by 2030, as part of its broader efforts to combat climate change and promote clean energy.{{Cite web |date=2023-08-22 |title=Biden-Harris Administration Approves Fourth Major Offshore Wind Project {{!}} U.S. Department of the Interior |url=https://www.doi.gov/pressreleases/biden-harris-administration-approves-fourth-major-offshore-wind-project |access-date=2025-03-06 |website=www.doi.gov}}
As of 2025, multiple projects are under development along the U.S. coasts, with large-scale offshore wind farms, such as Vineyard Wind in Massachusetts and South Fork Wind in New York, expected to begin operation in the coming years.{{Cite web |last=Hand |first=Karissa |date=February 22, 2024 |title=Vineyard Wind, America's First Large-Scale Offshore Wind Farm, Delivers Full Power from 5 Turbines to the New England Grid |url=https://www.mass.gov/news/vineyard-wind-americas-first-large-scale-offshore-wind-farm-delivers-full-power-from-5-turbines-to-the-new-england-grid |url-status=live |access-date=March 5, 2025 |website=Commonwealth of Massachusetts}}

There is more than 16 GW of capacity planned for the Atlantic Coast. The map at right shows leases executed by the Bureau of Ocean Energy Management (BOEM) for the outer continental shelf off the Massachusetts and Rhode Island coasts, the first offshore wind energy area to be opened for auction, in 2014 (lease assignments as of 2022).{{cite web | publisher = Bureau of Ocean Energy Management | url = https://www.boem.gov/renewable-energy/state-activities/massachusetts-leases-ocs-0500-bay-state-wind-and-ocs-0501 | access-date = 2022-10-23 | title = Massachusetts Leases OCS-A 0500 (Bay State Wind) And OCS-A 0501 (Vineyard Wind)}}File:Wind energy leases offshore Massachusetts and Rhode Island, 2022.pngBecause of its shallow waters and average offshore wind speeds in excess of 9 m/s, the coast off Massachusetts has the greatest potential offshore wind production in the US, at more than 1 million GWh per year, followed by that of the Gulf Coast states.{{cite tech report | title = 2016 Offshore Wind Energy Resource Assessment for the United States |author=Walt Musial |author2=Donna Heimiller |author3=Philipp Beiter |author4=George Scott |author5=Caroline Draxl | publisher = National Renewable Energy Laboratory | date = September 2016 | number = NREL/TP-5000-66599 | page = viii | url = https://www.nrel.gov/docs/fy16osti/66599.pdf | access-date = 2022-10-23}} Massachusetts energy law committed the state to purchasing 5,600 MW of offshore wind capacity by 2035. The shallow waters off the New England coast and proximity to load centers such as Boston, Providence, and Long Island make this area the most economical for both construction of wind farms and delivery of power to favorable nodes on the electric grid.
In 2019, the New York Climate Leadership and Community Protection Act was enacted. Among other requirements, the law mandates that 70% of the state's electricity be generated from renewable sources by 2030. To meet this goal, New York hopes to install 9,000 MW of offshore wind capacity by 2035.{{Cite web |title=About Offshore Wind |url=https://www.nyserda.ny.gov/All-Programs/Offshore-Wind/About-Offshore-Wind |access-date=2025-03-06 |website=NYSERDA}}New York has set a target of procuring 9,000 MW of offshore wind capacity by 2035. In February 2022, an auction for 6 lease areas in the New York Bight ended at $4.37 billion, with one area going for over one billion dollars. The combined areas could yield more than 5.6 gigawatts for an annual energy production of 19.6 TWh.{{cite web |last1=Foxwell |first1=David |date=26 February 2022 |title=US offshore wind auction blows oil and gas lease sales out of the water |url=https://www.rivieramm.com/news-content-hub/us-offshore-wind-auction-blows-oil-and-gas-lease-sales-out-of-the-water-69940 |website=Riviera}}{{cite web |last1=Lewis |first1=Michelle |date=25 February 2022 |title=US offshore wind auction for NY Bight is final, attracts a record $4.37B in bids |url=https://electrek.co/2022/02/25/us-offshore-wind-auction-attracts-a-record-2b-in-bids-and-its-not-even-done-yet/ |url-status=live |archive-url=https://web.archive.org/web/20220226080636/https://electrek.co/2022/02/25/us-offshore-wind-auction-attracts-a-record-2b-in-bids-and-its-not-even-done-yet/ |archive-date=26 February 2022 |website=Electrek}}{{Cite web |last=McCrone |first=Brian X. |title=European Energy Giants Still Dominate Future of Offshore Wind in US |url=https://www.nbcphiladelphia.com/news/national-international/changing-climate/offshore-wind-auction-atlantic-bight-nj-ny/3162124/ |access-date=2022-03-07 |website=NBC10 Philadelphia}}

The NREL estimates that the Great Lakes have a potential capacity of 160 GW that could be generated by fixed-bottom turbines. If floating foundation technology becomes viable, an additional capacity of 415 GW could be installed.{{Cite web |title=Exploring Offshore Wind Energy Opportunities in the Great Lakes |url=https://www.nrel.gov/news/program/2023/exploring-offshore-wind-energy-opportunities-in-the-great-lakes.html#:~:text=Wind%20resource%20assessments%20estimate%20that,for%20floating%20wind%20energy%20systems |archive-url=http://web.archive.org/web/20250227221347/https://www.nrel.gov/news/program/2023/exploring-offshore-wind-energy-opportunities-in-the-great-lakes.html |archive-date=2025-02-27 |access-date=2025-03-06 |website=www.nrel.gov}}
Despite the high potential, there are still obstacles to construction and development. Both the St. Lawrence Seaway and Welland Canal locks that connect the lakes to the Atlantic Ocean are too narrow to accommodate the large ocean vessels used to install offshore turbines. All the materials must either be transported through these locks, or built on the lakes themselves.
A Great Lakes project would be the first to be installed in an icy climate. While it is not expected to be a significant hurdle to development, it does raise some uncertainty.
The turbines would have to be constructed far enough from shore to assuage concerns about their impact on viewsheds. Other issues that might hinder deployment include concerns about bird and bat collisions and competition with land-based utility-scale wind and solar installations that are currently less expensive than proposed offshore wind.
Some Great Lakes states have signed a bipartisan federal-state memorandum of understanding (MOU) to create the Great Lakes Offshore Wind Energy Consortium to support the review of proposed offshore wind energy projects. Illinois, Michigan, Minnesota, New York, and Pennsylvania are all currently parties to the MOU.{{Cite web |title=Fact Sheet—Great Lakes Offshore Wind Energy Consortium |url=https://www.glc.org/wp-content/uploads/2016/10/GLWC-MOU-FactSheet-Final.pdf |url-status=live |access-date=March 5, 2025 |website=Great Lakes Commission}}
The Illinois House of Representatives recently passed H.B.2132, or the Illinois Rust Belt to Green Belt Pilot Program Act. If the bill is enacted, Illinois will procure at least one new utility-scale offshore wind project with a capacity of at least 150 MW.{{Cite web |title=Bill Status of HB2132 |url=https://ilga.gov/legislation/BillStatus.asp?DocNum=2132&GAID=17&DocTypeID=HB&LegId=145649&SessionID=112&GA=103 |url-status=live |access-date=March 5, 2025 |website=Illinois General Assembly}}

Although the waters of the Pacific Ocean tend to be deeper closer to shore than in the Atlantic, experts are still curious about the region's potential for offshore wind. There are an estimated 400 GW of potential capacity for offshore wind off the coast of the western United States.{{Cite web |date=2025-01-16 |title=West Coast Offshore Wind Industry Brings Energy Benefits, but Not Without Challenges |url=https://www.pnnl.gov/news-media/west-coast-offshore-wind-industry-brings-energy-benefits-not-without-challenges |access-date=2025-03-06 |website=www.pnnl.gov}} However, because these waters are too deep for current fixed-bottom turbine technology, development will likely have to wait until floating foundations become viable.{{Cite web |title=Surveying Deep-sea Corals, Sponges, and Fish Habitat Off the U.S. West Coast: Background: Wind: NOAA Office of Ocean Exploration and Research |url=https://oceanexplorer.noaa.gov/explorations/19express/background/wind/wind.html |access-date=2025-03-06 |website=oceanexplorer.noaa.gov}} The Pacific Northwest National Laboratory suggests that floating turbines could bring 33 GW of offshore wind capacity by 2050 once this happens.
Farther away from the U.S. mainland, Hawaii has also been considered as a potential location to develop offshore wind. The National Renewable Energy Laboratory estimates that there are potentially 28 GW of offshore wind technical capacity that could be installed off the coast of Hawaii. However, this would also likely rely on the development of floating technology, as these waters are too deep for fixed-bottom foundations.{{Cite web |title=Wayback Machine |url=https://www.nrel.gov/docs/fy16osti/65481.pdf |archive-url=http://web.archive.org/web/20250223042838/https://www.nrel.gov/docs/fy16osti/65481.pdf |archive-date=2025-02-23 |access-date=2025-03-06 |website=www.nrel.gov}}{{multiple image

=Gulf Coast=
The NREL estimates that the Gulf of Mexico holds about 37% of the United States' total offshore wind potential. Oil and gas interests have already developed a transmission network that offshore wind could potentially use to assist its development; however, future transmission planning would still be required during rollout.{{Cite web |title=Gulf of Mexico Offshore Wind Transmission |url=https://www.nrel.gov/wind/gulf-of-mexico-offshore-wind-transmission.html#:~:text=The%20Gulf%20of%20Mexico%20represents,Mississippi,%20Louisiana,%20and%20Texas |archive-url=http://web.archive.org/web/20250222141025/https://www.nrel.gov/wind/gulf-of-mexico-offshore-wind-transmission.html |archive-date=2025-02-22 |access-date=2025-03-06 |website=www.nrel.gov}}

Federal regulation and incentives
The Energy Policy Act of 2005 provided for tax credits and other incentives for production of wind power, authorizing the development of a regulatory framework for environmental reviews of proposed offshore wind projects.{{Cite web |title=National Environmental Policy Act and Offshore Renewable Energy {{!}} Bureau of Ocean Energy Management |url=https://www.boem.gov/renewable-energy/national-environmental-policy-act-and-offshore-renewable-energy#:~:text=The%20Energy%20Policy%20Act%20of,of%20proposed%20offshore%20wind%20projects |access-date=2025-03-06 |website=www.boem.gov}} This framework allows for a process where:
The construction of an offshore wind farm involves a three-phase permitting process. First, the proponents must lease the seafloor from its owner – typically this will be Outer Continental Shelf, the federal seafloor which is leased by the BOEM under the Outer Continental Shelf Lands Act — but small wind projects can be constructed in state waters as well. The BOEM is the federal agency responsible for determining offshore areas where wind farms may be built in federal waters.{{cite web |title=State Activities |url=http://www.boem.gov/Renewable-Energy-State-Activities/ |access-date=May 20, 2015 |publisher = Bureau of Ocean Energy Management}} It sells leases to qualified bidders.{{Cite news |last1=Cardwell |first1=Diane |date=January 30, 2015 |title=Offshore Wind Farm Leases Draw Few Bids from Wary Industry |newspaper=The New York Times |url=https://www.nytimes.com/2015/01/30/business/energy-environment/offshore-wind-farm-leases-draw-few-bids-from-wary-industry.html?_r=0}} These leases may be awarded non-competitively, if only one proponent is interested in developing the area, or by auction.{{Cite web |title=Commercial Leases OCS-A 0520, 0521, And 0522 {{!}} Bureau of Ocean Energy Management |url=https://www.boem.gov/renewable-energy/state-activities/commercial-leases-ocs-0520-0521-and-0522 |access-date=2025-03-06 |website=www.boem.gov}} Once awarded, the lease areas can be further assigned and subdivided into separate projects.{{Cite web |date=November 3, 2022 |title=Pacific Wind Lease Sale 1 (PACW-1) for Commercial Leasing for Wind Power on the Outer Continental Shelf in California: Questions and Answers for Bidders |url=https://www.boem.gov/sites/default/files/documents/renewable-energy/state-activities/PACW-1%20Bidders%20Q%26amp%3BA_Update.pdf |url-status=live |access-date=March 6, 2025 |website=Bureau of Ocean Energy Management}}
Each project proponent, after winning an auction and making its initial lease payment, must file a Site Assessment Plan (SAP), which details the work required to evaluate the environmental conditions in the lease area, including both surface and seafloor conditions. After the SAP is approved, the proponent will install weather buoys and engage survey vessels to develop sufficiently detailed information to complete the design of the wind farm – this will include identifying protected species habitats, unexploded ordnance, shipwrecks, and geological formations that could interfere with either the foundations for wind turbines or the electrical cabling. After completing the survey, the proponent might choose to abandon the lease area if it appears development will be uneconomical, or else continue to final design and permitting, which culminates in the filing of a Construction and Operations Plan (COP).{{Cite web |date=June 2019 |title=Guidelines for Information Requirements for a Renewable Energy Site Assessment Plan (SAP) |url=https://www.boem.gov/sites/default/files/renewable-energy-program/BOEM-Renewable-SAP-Guidelines.pdf#:~:text=The%20purpose%20of%20the%20SAP,m)%20in%20height%20and%20diameter. |url-status=live |access-date=March 6, 2025 |website=Bureau of Ocean Energy Management}}
In addition to the federal permitting process, all wind farms require state permits for their connections to the on-shore electric grid; even if an offshore project is constructed entirely in federal waters its "export cables" will need to transit state waters to reach the shore. Other permits may be required to connect to the grid, such as certificate of public necessity, as well as private consents from an integrated electric utility or a regional transmission organization.{{Cite web |date=March 2024 |title=An Action Plan for Offshore Wind Transmission Development in the U.S. Atlantic Region |url=https://www.energy.gov/sites/default/files/2024-04/Atlantic_Offshore_Wind_Transmission_Plan_Report_v16_RELEASE_508C.pdf |url-status=live |access-date=March 6, 2025 |website=U.S. Department of Energy}}
=Federal permitting process=
During the federal permitting process, several U.S. federal agencies oversee different aspects of offshore wind development. The Bureau of Ocean Energy Management (BOEM) manages leasing and permitting on the Outer Continental Shelf, while the Federal Energy Regulatory Commission (FERC) regulates offshore transmission and grid interconnection.{{Cite web |title=National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States |url=https://www.boem.gov/sites/default/files/renewable-energy-program/National-Offshore-Wind-Strategy-report-09082016.pdf |url-status=live |access-date=March 6, 2025 |website=Bureau of Ocean Energy Management}} The National Oceanic and Atmospheric Administration (NOAA) provides environmental data and assesses marine ecosystem impacts.{{Cite web |last=Fisheries |first=NOAA |date=2025-03-03 |title=Offshore Wind Energy {{!}} NOAA Fisheries |url=https://www.fisheries.noaa.gov/topic/offshore-wind-energy |access-date=2025-03-06 |website=NOAA}} The U.S. Army Corps of Engineers (USACE) issues permits for waterway impacts, and the U.S. Fish and Wildlife Service (USFWS) evaluates effects on wildlife.

The offshore wind development process consists of several phases, beginning with planning and analysis, where BOEM identifies potential wind energy areas and publishes sale notices, typically taking six months to 1.5 years. In the leasing phase, BOEM holds lease auctions and awards leases to developers.{{Cite web |title=Regulatory Framework and Guidelines {{!}} Bureau of Ocean Energy Management |url=https://www.boem.gov/renewable-energy/regulatory-framework-and-guidelines |access-date=2025-03-06 |website=www.boem.gov}} The site assessment and characterization phase follows, lasting up to five years, during which the lessee conducts studies and submits a Construction and Operations Plan (COP) for BOEM review. The COP review period takes approximately two years, during which BOEM evaluates the plan and conducts environmental (EIS) and technical reviews. In the construction phase, which lasts one to two years, the lessee submits facility design and fabrication reports to the Bureau of Safety and Environmental Enforcement (BSEE) and begins project development. The project then moves into the operations and maintenance phase, lasting up to 35 years, where BSEE ensures compliance with safety and environmental regulations. Finally, the decommissioning phase takes one to two years, during which BSEE oversees the removal of infrastructure.{{Cite web |title=Renewable Energy {{!}} Bureau of Safety and Environmental Enforcement |url=https://www.bsee.gov/about-bsee/renewable-energy |access-date=2025-03-06 |website=www.bsee.gov}}

In January 2012, a "Smart from the Start" regulatory approach was introduced, designed to expedite the siting process while incorporating strong environmental protections. Specifically, the Department of Interior approved "wind energy areas" off the coast where projects can move through the regulatory approval process more quickly.{{cite web |url=http://www.renewableenergyworld.com/rea/news/article/2012/02/offshore-wind-one-step-closer-to-reality-in-the-mid-atlantic |title=Offshore Wind One Step Closer to Reality in the Mid-Atlantic |author=Kit Kennedy |date=February 2, 2012 |work=Renewable Energy World}}

In 2014, Secretary of the Interior Sally Jewell announced three new wind energy areas off the coast of North Carolina in accordance with the "Smart from the Start" approach, which totaled to around 307,590 acres of ocean. These three are the Kitty Hawk Wind Energy Areas (122,405 acres), the Wilmington West Wind Energy Areas (51,595 acres), and the Wilmington East Wind Energy Areas (133,590 acres). These locations were chosen through collaboration with the United States Coast Guard to ensure that these locations posed no risk to navigational safety while also protecting sensitive resources and habitats.{{Cite web |date=2014-08-11 |title=Secretary Jewell Announces Milestone for Commercial Wind Energy Development Offshore North Carolina {{!}} U.S. Department of the Interior |url=https://www.doi.gov/news/pressreleases/secretary-jewell-announces-milestone-for-commercial-wind-energy-development-offshore-north-carolina |access-date=2024-11-18 |website=www.doi.gov}} Aside from these locations, wind energy areas are currently leased to developers along the East Coast, West Coast, and the Gulf of Mexico.{{Cite web |title=Lease and Grant Information {{!}} Bureau of Ocean Energy Management |url=https://www.boem.gov/renewable-energy/lease-and-grant-information |access-date=2025-04-21 |website=www.boem.gov |language=en}}

=National Environmental Policy Act=
Like other major permitting actions, approval of the construction and operations plan is subject to the National Environmental Policy Act and requires preparation of an environmental impact statement (EIS). BOEM is the lead federal agency in the EIS process, coordinating input from other federal agencies including the Coast Guard, the Fish and Wildlife Service, the Maritime Administration, the National Park Service, and the Army Corps of Engineers. In addition to approving each individual project's COP, the BOEM also performs an environmental review prior to opening an area of seafloor to leasing, although this review is not as stringent as a full EIS. The initial review largely serves to identify areas which are not developable and thus should be excluded from leasing.{{Cite web |title=National Environmental Policy Act and Offshore Renewable Energy {{!}} Bureau of Ocean Energy Management |url=https://www.boem.gov/renewable-energy/national-environmental-policy-act-and-offshore-renewable-energy#:~:text=This%20regulatory%20framework%20establishes%20a,environmental%20topics,%20and%20modeling%20tools.&text=BOEM%20has%20developed%20white%20papers,documents%20and%20incorporated%20by%20reference. |access-date=2025-03-06 |website=www.boem.gov}}

=Tax incentives=
Current tax incentives for offshore wind are vital to the success of proposed projects. The upfront costs of building an offshore wind farm are extremely high. Tax incentives can help make these costs easier for developers to shoulder, and can ultimately lessen the burden on energy consumers by lower the price what is generated by the wind farm. These can come in the form of investment tax credits (ITCs) and production tax credits (PTCs).{{Cite book |last=Hansen |first=Tyler A. |url=https://download.ssrn.com/2024/8/29/4940878.pdf?response-content-disposition=inline&X-Amz-Security-Token=IQoJb3JpZ2luX2VjENn%2F%2F%2F%2F%2F%2F%2F%2F%2F%2FwEaCXVzLWVhc3QtMSJHMEUCIBGD%2F7jgUhJnDUSgbBHkoqEd23b6nujg5uXnl6QFBJ7DAiEA%2FQT26sptk6c%2BeS0kAKeotO%2BzmG8BiQIFYIH93YD0XaAqvQUIIhAEGgwzMDg0NzUzMDEyNTciDK0tjJ20AET8FWKwyyqaBUOBawfMpqBiAR0WkgeaqIo4AzMKojJGrzxxBRChwcSCHB4zPZ10lcgr5xkxVPKUPE0thafbSbog4dhSx32ZvwngC%2FRqjItLav0l4jlHVUH9zgPajZj14n9OzIJ9JE%2Bws5ET%2B9bPwIxJAP0%2FyP%2FighWozXTkeV6JQeGixWfh4HwYgFvtdM5yCmIQ%2BmzH48%2BT%2Fp1%2FvrFIjQhXFHlWQmxnFO0hmBwFVFdZvW9LUb0A7MhLIHmhSOZ2Us2rFmFlnkmqWu0%2F7cp7TU52DpjbN10GsSHemF%2FAyKIs8b6vQs5lE4GBL8c8GD22eUdqJgY0tocj1WlLHtzPI3G2ZThwm9ejjrysal1GVcAbQVgeyqLfZ0bA%2B5R8eTkTV4X7QN8UseE4DHXYLV42cw%2FBsP%2BpDQ27Rg0BIywkRmZwSGq5raAuY3pacaJLm%2BpG51c%2Bu%2F97sJc0JIFt8olz9N7EoiaF53rX7OVUboO0G0dy9Xg2Kdn42Y9Y3dHRF7Ig9pSSrdk9IR9o5jAgRG%2B4JQ%2BemO4XoexppqLWfvPEDWNBRu30kIlVjnrEOD70aAFZpPfqyEa8OmpRsOmhUZ2iElcw9dEtbaoasXaqlSiX4gP7d6rMaGbng0MGXLoQfvQI%2BxNN7V6j6fYfeGK%2B7PO%2BCrluiSMQH15iBKcnCrIKHYuSMSKpIF5hENmWVeb%2BgzLEp2FVzIJSug5dDGXxbyjvL%2FOdvhdx0F4GJ%2BR%2FcbGexL4VBmctvGEnHdkU9wPFXM1YfD45SiV0XKDuTWck5VIGSDNulqrq76zsDQwjTvBAQL75BN2xxlB2ykx2zZcfqJJ8IYu5KudzLH84EGNHzuN08evdmhiXyzuTS8u2L%2FclsVHvFtKQVihMORseq3aCJvymUr9%2BpDCg2qO%2BBjqxASmpakE0m8ITJppaiyUrjs9Pmu6ZoQo7kL8Hf7W7H56QavHT4kg2Rzf8uPWPaQ0G61P2Mq%2BpiYFUlmTsgBrs8MzwNmS23A9Q7GyYl6%2BbYYSd0lGxVsnYamoWvTqZF5fIzJsOK1GpLDYLNfKW8hHZdGvJyZC%2FIhLEA44CKQTY0EDHBzpxvfeUCQmlHRgjASQgsRvlTZCroH28dbVovxbEF2Q4ypttLYN4esWR6MnZX7kOUg%3D%3D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20250306T014256Z&X-Amz-SignedHeaders=host&X-Amz-Expires=300&X-Amz-Credential=ASIAUPUUPRWEY44NJJNH%2F20250306%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Signature=1cd3f7dafcb6f9c52053e9af03f82bdee7868adb46e13e362741b6f44cfab035&abstractId=4940878 |title=Managing Complex Systems in a Changing World: Insights from Sustainable Energy and Beyond |last2=Tripp |first2=Ryan |last3=Wilson |first3=Elizabeth J. |location=Hanover, NH |pages=1–44 |chapter=De-Risking Offshore Wind: Developing a New Sector through Turbulent Times}}
In December 2020, Congress approved the Taxpayer Certainty and Disaster Tax Relief Act (TCDTRA), which modifies section 48 of the Internal Revenue Code that relates to tax liability for energy projects. This modification included a 30% investment tax credit for U.S. offshore wind farms beginning construction between 2017 and 2026.{{cite web |last1=Morehouse |first1=Catherine |title=Federal stimulus includes wind, solar tax credit extensions, adds first US offshore wind tax credit |url=https://www.utilitydive.com/news/federal-stimulus-includes-wind-solar-tax-credit-extensions-adds-first-us/592572/ |website=Utility Dive |archive-url= https://web.archive.org/web/20201223181028/https://www.utilitydive.com/news/federal-stimulus-includes-wind-solar-tax-credit-extensions-adds-first-us/592572/ |archive-date=December 23, 2020 |date=December 22, 2020 |url-status=live}}[https://web.archive.org/web/20201221185059/https://rules.house.gov/sites/democrats.rules.house.gov/files/BILLS-116HR133SA-RCP-116-68.pdf Democrats Rules House]
The Inflation Reduction Act (IRA), enacted in August 2022, expanded the investment tax credit (ITC) by adding two ten percent stackable, or bonus, credits. One has a content-based requirement that twenty percent of the raw materials are mined, produced, or manufactured in the United States; however, the current US offshore wind supply chain might not be advanced enough for developers to easily meet this requirement. The other credit requires that the onshore facilities servicing offshore wind projects be sited in "energy communities" that are currently considered dependent on fossil fuels. Qualifying areas have at least 0.17% of total employment or 25% of revenues from the fossil fuel industry. The IRA also subsidized multiple stages of offshore wind development, such as the cost of mining required raw minerals and wind turbine installation vessels. To support efforts to develop a coordinated offshore wind transmission network, the IRA allocated $100 million to fund research, planning, and modeling in the Pacific.
The IRA extended a production tax credit (PTC) through 2024, and introduced manufacturing tax credits. However, initial uncertainty regarding qualification requirements delayed clarity for developers, and most projects have opted for the ITC over the PTC due to its greater financial benefit under current conditions.
To appease oil and gas interests, the IRA included a provision dictating that for ten years after the bill's passage, BOEM may not award a new offshore wind lease unless it has held offered sixty million acres for oil and gas leasing within a year of the wind auction.

The expansion of offshore wind energy in the United States presents significant economic opportunities, particularly for coastal regions. According to the American Clean Power Association, offshore wind development is expected to generate 56,000 jobs by 2030, with additional indirect employment generated through supply chain growth and port infrastructure investments.{{Cite web |last=Ahluwalia |first=Esha |last2=ACP |date=2024-10-01 |title=Why Offshore Wind Power is Key to Meeting U.S. Electricity Demand |url=https://cleanpower.org/blog/why-offshore-wind-power-is-key-to-meeting-u-s-electricity-demand/#:~:text=By%202030,%20the%20offshore%20wind,reliance%20on%20foreign%20energy%20sources. |access-date=2025-02-21 |website=ACP}} In addition, in 2019, the University of Delaware and the Danish Energy and Climate Academy jointly opened the first US skills training program for offshore wind energy professionals.{{Cite web |title=Offshore Wind Skills Academy |url=https://www.pcs.udel.edu/wind/ |access-date=2020-04-18 |website=University of Delaware Div. of Professional and Continuing Studies}} This development not only diversifies the national energy portfolio but also strengthens domestic manufacturing and maritime industries, fostering long-term economic growth in underserved coastal areas.

Beyond these immediate local conflicts, broader socioeconomic dynamics also shape opposition to offshore wind. Research has shown that opposition is not always purely grassroots but is often influenced by larger political and economic networks, including fossil fuel interests and conservative think tanks, which provide information subsidies to amplify concerns about offshore wind's economic and environmental impact.{{Cite journal |last=Slevin |first=Isaac |last2=Kattrup |first2=William |last3=Marcil |first3=Charlotte |last4=Roberts |first4=J.

= Environmental =
Offshore wind energy development in the United States has both positive and negative environmental impacts. One of the primary environmental benefits is the reduction of greenhouse gas emissions by displacing fossil fuel-based energy sources. According to the Ocean Conservancy, the Biden Administration's goal of 30 GW of offshore energy by 2030 could reduce carbon emissions by up to 78 million metric tons annually and generate enough energy to power 10 million homes. Additionally, a study conducted in 2014 in Michigan analyzed the effects of offshore wind farms on the Great Lakes region and found improvement in local air quality.{{Cite journal |last=Nordman |first=Erik |last2=VanderMolen |first2=Jon |last3=Gajewski |first3=Betty |last4=Isely |first4=Paul |last5=Fan |first5=Yue |last6=Koches |first6=John |last7=Damm |first7=Sara |last8=Ferguson |first8=Aaron |last9=Schoolmaster |first9=Claire |date=2015-04-11 |title=An integrated assessment for wind energy in Lake Michigan coastal counties |url=https://setac.onlinelibrary.wiley.com/doi/10.1002/ieam.1602 |journal=Integrated Environmental Assessment and Management |volume=11 |issue=2 |pages=287–297 |doi=10.1002/ieam.1602 |issn=1551-3777}} Results from this study indicated a decrease in all common air pollutants as a result of the development of offshore wind energy, as well as a projected 25% decrease in CO2 emissions by 2050.{{Cite journal |last=Browning |first=Morgan S. |last2=Lenox |first2=Carol S. |date=2020-10-15 |title=Contribution of offshore wind to the power grid: U.S. air quality implications |url=https://www.sciencedirect.com/science/article/abs/pii/S0306261920309867 |journal=Applied Energy |volume=276 |pages=115474 |doi=10.1016/j.apenergy.2020.115474 |issn=0306-2619 |pmc=7443953}}
There is also evidence that below the surface, offshore wind farms can provide positive environment effects. The covering used to protect the anchoring mechanisms have been shown to create habitats for marine life.{{Cite journal |last=Hutchison |first=Zoë L. |last2=Bartley |first2=Monique LaFrance |last3=Degraer |first3=Steven |last4=English |first4=Paul |last5=Khan |first5=Anwar |date=2020-12-16 |title=Offshore Wind Energy and Benthic Habitat Changes: Lessons from Block Island Wind Farm |url=https://tos.org/oceanography/article/offshore-wind-energy-and-benthic-habitat-changes-lessons-from-block-island-wind-farm |journal=Oceanography |volume=33 |issue=4 |pages=58–69 |doi=10.5670/oceanog.2020.406|hdl=10023/21421 |hdl-access=free }}{{Cite journal |last=Wilber |first=Dara H |last2=Brown |first2=Lorraine |last3=Griffin |first3=Matthew |last4=DeCelles |first4=Gregory R |last5=Carey |first5=Drew A |date=2022-05-23 |editor-last=Pol |editor-first=Michael |title=Demersal fish and invertebrate catches relative to construction and operation of North America's first offshore wind farm |url=https://academic.oup.com/icesjms/article/79/4/1274/6555702 |journal=ICES Journal of Marine Science |language=en |volume=79 |issue=4 |pages=1274–1288 |doi=10.1093/icesjms/fsac051 |issn=1054-3139|doi-access=free }} Additionally, artificial reefs can be installed to mitigate damage to marine life resulting from turbine installation.{{Cite journal |last=Wilson |first=Jennifer C. |last2=Elliott |first2=Michael |date=2009-03-14 |title=The habitat‐creation potential of offshore wind farms |url=https://onlinelibrary.wiley.com/doi/10.1002/we.324 |journal=Wind Energy |volume=12 |issue=2 |pages=203–212 |doi=10.1002/we.324 |issn=1095-4244}} Furthermore, depending on how fishing is managed near offshore wind turbines, wind farms could function similarly to marine protected areas, which could have tremendously positive impacts on the environment, protecting it from extractive activities and creating an artificial reef effect that could propagate up the food web, increasing local biodiversity and abundance.{{Cite journal |last=Wang |first=Lijing |last2=Wang |first2=Bangguo |last3=Cen |first3=Wenxi |last4=Xu |first4=Rui |last5=Huang |first5=Yuwei |last6=Zhang |first6=Xin |last7=Han |first7=Yinghui |last8=Zhang |first8=Yuanxun |date=2024-05-01 |title=Ecological impacts of the expansion of offshore wind farms on trophic level species of marine food chain |url=https://www.sciencedirect.com/science/article/abs/pii/S100107422300205X |journal=Journal of Environmental Sciences |volume=139 |pages=226–244 |doi=10.1016/j.jes.2023.05.002 |issn=1001-0742}} Because of the spillover effect, nearby regions may experience similar benefits.{{Cite journal |last=Halouani |first=Ghassen |last2=Villanueva |first2=Ching-Maria |last3=Raoux |first3=Aurore |last4=Dauvin |first4=Jean Claude |last5=Ben Rais Lasram |first5=Frida |last6=Foucher |first6=Eric |last7=Le Loc'h |first7=François |last8=Safi |first8=Georges |last9=Araignous |first9=Emma |last10=Robin |first10=Jean Paul |last11=Niquil |first11=Nathalie |date=2020-12-01 |title=A spatial food web model to investigate potential spillover effects of a fishery closure in an offshore wind farm |url=https://www.sciencedirect.com/science/article/abs/pii/S0924796320301305 |journal=Journal of Marine Systems |volume=212 |pages=103434 |doi=10.1016/j.jmarsys.2020.103434 |issn=0924-7963}}
However, offshore wind development also poses potential environmental risks. The construction and maintenance of these farms involve the potential to harm local marine life. Coastal bird species can be harmed by the development of offshore wind farms though studies suggest that the risk is lower compared to onshore wind farms.{{Cite journal |last=Garthe |first=Stefan |last2=Schwemmer |first2=Henriette |last3=Peschko |first3=Verena |last4=Markones |first4=Nele |last5=Müller |first5=Sabine |last6=Schwemmer |first6=Philipp |last7=Mercker |first7=Moritz |date=2023-04-13 |title=Large-scale effects of offshore wind farms on seabirds of high conservation concern |url=https://www.nature.com/articles/s41598-023-31601-z |journal=Scientific Reports |volume=13 |issue=1 |pages=4779 |doi=10.1038/s41598-023-31601-z |issn=2045-2322 |pmc=10102167}} Concerns also center around offshore wind negatively impacting the endangered North Atlantic right whale, due to possible vessel strikes and entanglement with fishing gear. These concerns are often expressed by groups that are opposed to offshore wind development, who assert that offshore wind could bring about the extinction of the North Atlantic right whale.{{Cite web |title=Home {{!}} SaveLBI.org - LBI Coalition for Wind Without Impact |url=https://www.savelbi.org/ |access-date=2025-04-21 |website=Save LBI |language=en}}{{Cite web |last=Brady |first=Bonnie |date=2025-04-11 |title=How NY's offshore wind power threatens whales, ships and more |url=https://nypost.com/2025/04/10/opinion/how-nys-offshore-wind-power-threatens-whales-ships-and-more/ |access-date=2025-04-21 |language=en-US}}
However, it is important to note that scientific studies have found no direct link between offshore wind activities and whale deaths.{{Cite web |last=Fisheries |first=NOAA |date=2024-03-14 |title=Frequent Questions—Offshore Wind and Whales {{!}} NOAA Fisheries |url=https://www.fisheries.noaa.gov/new-england-mid-atlantic/marine-life-distress/frequent-questions-offshore-wind-and-whales |access-date=2025-03-03 |website=NOAA}} Turbine construction, particularly pile driving, generates underwater noise that can disturb marine mammals and fish.{{Cite journal |last=Bailey |first=Helen |last2=Senior |first2=Bridget |last3=Simmons |first3=Dave |last4=Rusin |first4=Jan |last5=Picken |first5=Gordon |last6=Thompson |first6=Paul M. |date=2010-06-01 |title=Assessing underwater noise levels during pile-driving at an offshore windfarm and its potential effects on marine mammals |url=https://www.sciencedirect.com/science/article/abs/pii/S0025326X10000044 |journal=Marine Pollution Bulletin |volume=60 |issue=6 |pages=888–897 |doi=10.1016/j.marpolbul.2010.01.003 |issn=0025-326X}}{{Cite journal |last=Popper |first=Arthur N. |last2=Hastings |first2=Mardi C. |date=March 2009 |title=The effects of human‐generated sound on fish |url=https://doi.org/10.1111/j.1749-4877.2008.00134.x |journal=Integrative Zoology |volume=4 |issue=1 |pages=43–52 |doi=10.1111/j.1749-4877.2008.00134.x |issn=1749-4877}} To mitigate these impacts, developers have implemented measures such as seasonal restrictions on pile driving to avoid sensitive breeding and migration periods, the use of bubble curtains to dampen underwater noise, and real-time monitoring of marine mammal activity to temporarily halt construction when animals are nearby.https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4940878 Additionally, adaptive management strategies, including dynamic fisheries management and habitat restoration initiatives, have been proposed to address concerns about potential disruptions to fish populations.
Another source of concern cited by those opposed to offshore wind is the possibility of pollution, especially when turbines break or are decommissioned, though the latter phase would not occur until years after an offshore wind farm becomes operational. In July 2024, a blade from a GE Vernova turbine in the Vineyard Wind project off the coast of Nantucket fractured, sending large pieces of debris and smaller shards of fiberglass into the water.{{Cite web |last=Beaubouef |first=Bruce |date=2024-07-21 |title=Feds shut down Vineyard Wind project following turbine blade failure |url=https://www.offshore-mag.com/renewable-energy/article/55127394/feds-shut-down-vineyard-wind-project-following-turbine-blade-failure |access-date=2025-04-25 |website=Offshore |language=en}} Less than a month later, another GE Vernova turbine blade failed in the United Kingdom.{{Cite web |last= |title=GE Vernova falls after turbine blade failure at offshore UK wind farm |url=https://www.reuters.com/business/energy/ge-vernova-falls-after-turbine-blade-failure-offshore-uk-wind-farm-2024-08-23/}} Still, the rate of blade failures is very low—3 blade failures (the two described plus one other incident) only represent 0.00004% of the 70,000 blades manufactured in 2024.{{Cite web |last=Lavin |first=Nancy |date=2024-09-04 |title=The biggest problem facing offshore wind energy isn’t broken blades.
