A new report from energy research firm Wood Mackenzie puts a stark number on the cost of federal permitting slowdowns under the Trump administration: more than $121 billion in wind, solar, and storage investment now sits at risk. Published Monday, the report identifies 92 gigawatts of clean energy projects — enough to power roughly 69 million homes — facing heightened federal scrutiny following a series of policy changes that have stretched development timelines across the country.
Report identifies $121 billion in at-risk renewable investment
Wood Mackenzie’s Monday report focuses specifically on early-stage projects — the ones still working through development pipelines before construction even starts. That’s where permitting delays hit hardest. When approvals stall at the front end, investment decisions get pushed back or dropped entirely.
The 92 gigawatts under heightened scrutiny represents roughly 32% of the entire U.S. early-stage renewable pipeline. Nearly a third of the projects developers had planned to build now face an extra layer of federal review that simply didn’t exist before. That’s not a rounding error.
The $121 billion figure reflects the combined value of those early-stage wind, solar, and storage projects. Wood Mackenzie stopped short of saying all that investment will disappear but flagged these projects as carrying real risk as long as permitting timelines stay unpredictable.
Policy changes behind the permitting slowdown
The bottleneck traces back to several interlocking policy shifts. The most consequential: a Department of the Interior directive requiring senior-official approval for renewable energy permits at every stage of development—a single change that layered new bureaucracy onto a process already moving slowly.
Private-land developments aren’t insulated from this either. Many still require federal permits covering wetlands, wildlife impacts, or access roads, pulling them into the same review process. Wood Mackenzie identified wetland permitting, overseen by the U.S. Army Corps of Engineers, as the primary constraint for projects on private land.
Wind energy carries an additional burden. Airspace reviews conducted by the Department of Defense have been running behind, creating yet another queue developers must clear before moving forward. These reviews operate separately from the Interior directive, but they compound the overall delay—and together, these overlapping bottlenecks are hitting project types and land categories all at once.
On-the-ground impact: Cancellations and stalled capacity
The delays aren’t just slowing paperwork. Around 7 gigawatts of renewable capacity on federal land was either canceled or stalled in 2025 alone, according to Wood Mackenzie’s findings.
Federal funding withdrawals have compounded the damage. When projects lose both their permits and financing support in close succession, developers have fewer reasons to stay in the queue — and some are walking away.
The irony is hard to miss. The Trump administration has made expanding power supply a stated priority, largely to support surging electricity demand tied to AI data centers and industrial growth. Yet the permitting slowdowns are constraining exactly the kind of energy development that would add new capacity to the grid. Wood Mackenzie researcher Gaby Ackermann Logan put it plainly: “Without more coordinated and predictable processes, delays and uncertainty will continue to weigh on development timelines and investment decisions.” That’s not a forecast about some distant future—it describes what’s already underway.
Legislative efforts and broader context
Permitting reform isn’t a new idea, and it doesn’t break cleanly along party lines. Both congressional Republicans and Democrats have pushed legislation to speed up approvals for large energy projects, with broad appeal on both sides—the disagreement tends to center on which projects should benefit.
Wood Mackenzie noted that a bill passed by the House of Representatives last year would meaningfully accelerate permitting timelines if enacted, though its path through the Senate remains uncertain.
Permitting bottlenecks also predate the Trump administration by years. Slow approvals have long been a structural barrier to U.S. energy development across fuel types—fossil fuels, renewables, and transmission lines alike. The current policy changes have intensified the problem for renewables specifically, but the underlying dysfunction is systemic.
What the Wood Mackenzie report makes clear is the structural tension running through the current moment. The administration is skeptical of renewable energy and has used permitting policy as a lever to slow its development, while simultaneously wanting to expand power supply quickly to meet rising electricity demand. Those two goals are pulling in opposite directions, and the $121 billion figure is one measure of the distance between them.
7 GW of capacity canceled or stalled
The Wood Mackenzie report delivers several findings worth keeping in mind. The scale: $121 billion in early-stage investment and 92 gigawatts of capacity—about 32% of the U.S. renewable pipeline—are now subject to additional federal scrutiny. The mechanism: a Department of the Interior directive, slow wetland permitting through the Army Corps of Engineers, and delayed Defense Department airspace reviews are the main drivers. The real-world result: 7 gigawatts of federal-land capacity already canceled or stalled in 2025.
Legislative fixes exist on paper, but none have cleared Congress. Until permitting processes become more predictable, Wood Mackenzie suggests, investment risk across the renewable sector will stay elevated.
