The Trump administration’s FY2027 budget request for the Department of Energy proposes a reduction in funding for thirteen selected technology programs from $4.288 billion in FY2026 to $2.618 billion. This represents an overall decline of approximately 39 percent for these specific lines.
Funding for solar, wind, vehicle, and building programs faces the most significant cuts, dropping from a combined $1.005 billion to $40 million. Specifically, vehicle-related funding is set to decrease from $397 million to $20 million, while building-related programs fall from $288 million to $20 million.
The proposal eliminates annual funding for solar and wind programs, which previously received $220 million and $100 million respectively. Similarly, the annual hydrogen and fuel-cell program line is reduced from $160 million to zero, although regional hydrogen hubs remain nominally retained.
Other sectors see varied adjustments: funding for critical minerals is slated to rise from $83 million to $364 million. Geothermal energy remains steady at $150 million, and civilian nuclear funding is proposed to decrease by 9 percent, moving from $1.685 billion to $1.534 billion.
The budget request also impacts ARPA-E, with its total allocation decreasing from $350 million to $200.3 million. Project-specific funding within the organization is set to drop from $310 million to $160.3 million under the new proposal.
