Offshore Wind Projects Face Uncertainty as US Policy Shifts from IRA to OBBBA (2025-2026)

A stark divergence in U.S. energy policy, pivoting from the Inflation Reduction Act (IRA) to a fossil-fuel-centric agenda, has injected significant risk into the clean energy sector. The election of Donald Trump in November 2024 and the subsequent executive actions in early 2025 marked an abrupt reversal from the prior administration’s climate goals. For executives and investors, this shift invalidates previous investment theses built on stable, long-term clean energy incentives. The new framework prioritizes oil and gas maximization under an “American Energy Dominance” banner, directly threatening the project pipeline and manufacturing investments spurred by the IRA.

Clean Energy Project Risk, IRA Repeal vs. OBBBA Uncertainty

The transition from the Biden-Harris administration’s supportive IRA framework to the Trump administration’s “Unleashing American Energy” agenda has fundamentally altered project viability, replacing clear incentives with regulatory rollbacks and policy uncertainty. The result is a stalled clean energy deployment pipeline, as investors re-evaluate projects planned under a completely different set of financial and regulatory assumptions. This has put gigawatts of planned capacity at risk, particularly in capital-intensive sectors like US wind energy.

IRA Momentum Meets Policy Headwinds (2021-2024)

The period between 2021 and 2024 was characterized by a push to decarbonize, underpinned by the IRA. This legislation created powerful tax incentives and grants designed to accelerate the energy transition and build a domestic clean energy supply chain. The Harris platform was built on defending these policies to achieve goals like a carbon-free power sector by 2035. This created a favorable environment for investment in solar, wind, and battery storage, with numerous companies announcing new manufacturing facilities and projects based on the IRA’s long-term financial signals.

The “Unleashing American Energy” Reversal (2025-2026)

Beginning on January 20, 2025, the new administration moved swiftly to dismantle the previous policy structure. Key actions included the “Unleashing American Energy” executive order, which immediately restarted LNG export reviews and lifted restrictions on fossil fuel leasing. This was followed by proposals like “The One Big Beautiful Bill Act” (OBBBA), designed to replace IRA incentives with a framework favoring fossil fuels and creating a crisis for supply chains dependent on stable US China clean energy policy. The administration’s approach to US clean energy policy also included the formal withdrawal from the Paris Agreement, signaling a complete rejection of international climate commitments.

Geographic Impact, Domestic Manufacturing Shifts Under Trump’s Energy Policy

The policy reversal creates distinct regional winners and losers, shifting the geographic focus of energy investment away from emergent clean energy manufacturing hubs and back toward traditional fossil fuel-producing states. The uncertainty surrounding the future of IRA incentives threatens the viability of billions in factory investments announced between 2022 and 2024. While the US pivots, other nations are also grappling with energy security, as seen in Poland’s energy policy adjustments.

IRA-Spurred Manufacturing Hubs at Risk

A primary goal of the IRA was to reshore clean energy manufacturing to the United States, and analysis showed that industrial policy projects were a factor in the 2024 election. States across the country saw announcements for new solar panel, battery, and EV factories, creating “battery belts” and clean energy corridors. These investments are now at risk, as their financial models were heavily dependent on the IRA’s domestic content and manufacturing tax credits. The potential repeal of these credits undermines the competitiveness of these nascent U.S. facilities against established foreign supply chains.

Fossil Fuel States See Renewed Focus

The Trump administration’s agenda explicitly favors regions with significant oil, gas, and coal resources. Executive orders in 2025 reversed restrictions on energy production in Alaska and expanded leasing on federal lands, primarily benefiting states in the West and Gulf Coast. The renewed push for LNG exports further bolsters the economies of states like Texas and Louisiana. This shift redirects federal support and private capital toward hydrocarbon infrastructure, diverting it from the renewable projects that were gaining ground in other parts of the country.

Technology Commercialization, Fossil Fuels Prioritized Over Clean Tech Deployment

The administration’s policy direction directly influences which energy technologies are commercially favored, creating significant headwinds for renewables while providing a clear path for fossil fuels and, to some extent, nuclear power. The pivot highlights the core tenets of Trump and renewable energy policies, prioritizing incumbent energy sources over the deployment of less mature clean technologies. This environment alters the risk profile for a wide range of technologies, from grid management platforms developed by firms like Power Ledger to advanced battery materials from companies such as Energy X.

Clean Tech Acceleration Under the IRA

From 2021 to 2024, federal policy actively promoted a broad portfolio of clean technologies. The IRA’s tax credits for hydrogen, carbon capture, and sustainable aviation fuel were designed to create markets and drive down costs for technologies still on the path to commercial scale. This spurred a wave of pilot projects and investment announcements, with the goal of creating a self-sustaining clean energy ecosystem. The overarching goal was to use policy to accelerate technology adoption curves across the entire sector.

Fossil and Nuclear Resurgence Post-2025

The 2025-2026 policy landscape shows a clear preference for technologies that support the “American Energy Dominance” agenda. The administration has expedited permitting for oil and gas pipelines and LNG export terminals. In May 2025, President Trump signed executive orders to “Reinvigorate the Nuclear Industrial Base, ” signaling strong support for both existing and advanced nuclear reactors as a reliable, carbon-free power source. While some clean energy sectors face headwinds, others like geothermal, exemplified by companies such as Fervo Energy, continue to advance based on strong economics and corporate demand.

SWOT Analysis, US Clean Energy Investment After Policy Reversal

The strategic landscape for U.S. clean energy investment has been completely redefined by the policy shift of 2025. A SWOT analysis reveals that while the momentum from the IRA period created certain strengths, the sector now faces profound weaknesses and threats stemming from the new administration’s agenda. The new US EPA energy policy that dismantles prior regulations represents a significant threat to the industry’s stability.

Scenario Modelling, Investor Signals in a Post-IRA Energy Market

For investors and energy executives, the critical task is to identify the early signals that confirm the market’s new trajectory. If the Trump administration successfully uses budget reconciliation or other legislative tools to repeal major IRA provisions, watch for a wave of project cancellations and asset write-downs in the renewable sector throughout the remainder of 2026. This would confirm a long-term shift of capital away from clean energy deployment and toward fossil fuel infrastructure and exports.

• The most immediate signal to monitor is the pace of new LNG export approvals from the Department of Energy. A rapid acceleration of permits, as directed by the January 2025 executive order, indicates a strong commitment to maximizing gas exports.
• Watch for legal challenges from states and environmental groups against the administration’s deregulatory actions. The success or failure of these challenges will determine how quickly and effectively the policy reversals can be implemented.
• Monitor capital flows into the energy sector. A clear shift in private equity and institutional investment from renewable development to oil and gas production or nuclear technology would be a definitive signal of the market accepting the new policy reality.
• Pay close attention to state-level policy responses. Blue states may attempt to double down on their own clean energy incentives to counteract federal policy, creating a fragmented and complex national energy market.
