What Happened to Offshore Wind Energy?

Offshore wind energy, the generation of electricity from wind farms in bodies of water, has evolved from an ambitious concept to a cornerstone of global energy transition strategies. Its appeal lies in the stronger, more consistent wind speeds found at sea, leading to higher energy yields and less visual impact compared to onshore wind. The first commercial offshore wind farm was established in Denmark in 1991, marking the beginning of its journey.

For decades, the sector experienced steady growth, particularly in Europe, with increasing turbine sizes and falling costs. By the early 2020s, offshore wind was seen as a critical component for achieving decarbonization and energy security. The United States began to make significant strides, with the Block Island Wind Farm becoming operational in 2016 and the South Fork Wind Farm, the first commercial-scale project in federal waters, delivering power to New York in late 2023 and fully commissioned by March 2024. Global installed capacity reached 83 GW by the end of 2024, with 8 GW added that year, and a record 56 GW of new capacity awarded in government auctions.

However, 2025 proved to be a turbulent year, especially for the U.S. market. Macroeconomic headwinds, including persistent inflation, rising interest rates, and supply chain constraints, significantly increased project costs, making many previously viable projects uneconomical. This was exacerbated by a dramatic shift in U.S. federal policy. On January 20, 2025, the Trump administration issued a memorandum withdrawing areas from offshore wind leasing and halting new federal approvals, permits, and loans. This led to a series of project cancellations and halts, including major projects like Revolution Wind, Empire Wind, and Sunrise Wind, putting over 20 GW of planned capacity and an estimated $114 billion in investments at risk. The Department of the Interior also rescinded 3.5 million acres of designated Wind Energy Areas and paused five large-scale projects under construction in December 2025, citing national security concerns, though these pauses were later vacated by a federal court.

Despite the U.S. setbacks, the global market continued to expand, albeit with some challenges. In 2025, 9.3 GW of new offshore wind capacity was connected worldwide, bringing the total to 92.5 GW. China led installations for the eighth consecutive year, commissioning 6.6 GW, while Europe added nearly 2 GW. The industry recognized the need for policy adjustments, with countries like Germany and the UK exploring new auction designs, such as two-sided Contracts for Difference (CfDs), to reduce investor risk and ensure project delivery after a 2025 German auction round failed to attract bids.

As of August 2026, the offshore wind sector is navigating a complex landscape. Global installed capacity is projected to reach 420 GW by 2035, more than four times the current total. Floating offshore wind technology is rapidly scaling up, opening access to deeper waters and stronger winds, with significant events like the Floating Wind Europe conference in June 2026 and the Pacific Offshore Wind Summit in May 2026 highlighting its growing importance. In the U.S., while some projects like Revolution Wind began delivering power in March 2026, the market faces ongoing challenges from policy uncertainty and the need for a robust domestic supply chain. Globally, the focus is on balancing industrial and energy policy, strategic shifts to capture more value, and securing financial support to ensure the industry meets its ambitious targets.
