U.S. clean energy investments: 2026 Quarter 1 analysis

In Q1 2026, U.S. clean energy investments were heavily influenced by executive branch implementation and policy certainty. While electric power investments increased—driven by a massive nuclear project in Texas—manufacturing investments declined for the sixth consecutive quarter. Federal support strongly favored critical minerals and battery storage, while sectors like hydrogen, solar, and sustainable aviation fuel (SAF) faced mixed outcomes due to fragile policy support and tightened tax credit eligibility windows.

• Actual clean electricity production investment in Q1 2026 totaled approximately $24 billion, with solar accounting for $11.1 billion, storage for $6.7 billion, and wind for $6.2 billion.
• Announced nuclear investments surged to $26.7 billion in Q1 2026, entirely attributed to Project Matador, a 17GW hybrid energy and data infrastructure campus in Carson County, Texas, featuring four Westinghouse AP1000 reactors.
• Actual manufacturing investments declined for the sixth consecutive quarter, totaling $7.7 billion in Q1 2026, down from approximately $9 billion in Q4 2025. Battery manufacturing led these investments at $4.8 billion.
• The federal government implemented several actions to support the domestic critical minerals supply chain in Q1 2026, including a White House Proclamation on processed critical minerals, the launch of a $10 billion direct loan for Project Vault to establish a U.S. Strategic Critical Minerals Reserve, and the creation of the Forum on Resource Geostrategic Engagement (FORGE).
• Solar and wind projects faced increased pressure in Q1 2026 due to accelerated tax credit termination timelines and narrower construction rules; developers must begin construction by July 4, 2026, or place projects in service by December 31, 2027, to remain eligible for 45Y PTC/48 E ITC credits.
• Sustainable Aviation Fuel (SAF) actual investments in Q1 2026 were 46% lower than in Q1 2025, largely due to OBBBA reducing the 45Z tax credit rate from $1.75/gallon to $1.00/gallon.
• The Department of Defense (DOD) has effectively banned all new wind projects, a policy that is currently being challenged in court.
• FY26 appropriations included a topline cut of roughly $1 billion for Department of Energy (DOE) line items related to clean energy priorities compared to the FY25 package.
