Why it Matters

The House Science, Space, and Technology Committee is set to examine a Department of Energy Fiscal Year 2027 budget request that wants to boost nuclear weapons spending while gutting civilian science and clean energy programs. The hearing, scheduled for Wednesday, June 10 at 2:00 p.m. in 2318 Rayburn House Office Building, arrives as Congress weighs whether the administration's energy priorities align with the country's long-term research and grid security needs, and whether a department reshaped by workforce cuts can even execute the budget it's requesting.

The Big Picture

The Trump administration's DOE budget request asks for $53.91 billion in total discretionary budget authority for FY2027, a $4.81 billion increase from fiscal year 2026 levels. Nearly all of the increase flows to defense and nuclear weapons programs, while civilian energy and science accounts absorb deep reductions.

The Federation of American Scientists described the request as a mixed picture of "the Good, the Bad, and the Ugly," noting that a 10 percent overall increase masks dramatic cuts to civilian science programs. The Office of Electricity would be cut 22 percent from FY2026 levels, according to Utility Dive. Nuclear fuel cycle research and development would be slashed by 55 percent, dropping to $218.5 million, according to the American Nuclear Society.

Programs for solar, wind, hydrogen, and fuel cell technologies, which had already been proposed for elimination in the fiscal year 2026 request, remain at zero in the FY2027 proposal, according to FAS analysis. An analysis by Taxpayers for Common Sense, published in early May, catalogued the winners and losers in granular detail, providing a roadmap for the partisan arguments that are likely to surface at the DOE FY2027 budget hearing.

What They're Saying

DOE Secretary Chris Wright testified before four House and Senate committees in April 2026, and the fault lines that emerged then are expected to reappear before the House Science Committee.

A Holland & Knight summary of those April hearings described "sharp partisan divides, a focused concern on rising gas prices amid the ongoing conflict with Iran and consistent themes shaping DOE's priorities." Republicans pressed the energy dominance and nuclear security arguments that underpin the administration's budget architecture. Democrats countered that grant terminations, permitting backlogs for renewable energy, and cuts to weatherization and consumer assistance programs were raising costs for ordinary Americans.

Democrats also targeted proposed funding reductions to ARPA-E and other science programs, arguing, per Holland & Knight's account, "that such cuts would ultimately increase costs by weakening efficiency, innovation and long-term supply."

What's at Stake

For the Department of Energy

Earlier in 2026, the Department of Energy identified thousands of positions as potentially nonessential in the context of DOGE-driven workforce reductions, according to AP News.

Latitude Media reported that employees across agency offices described the atmosphere at DOE as "demoralizing," "sad," and like "a hostile takeover." Democratic members of the Energy and Commerce Committee had already sent letters condemning DOE firings as "reckless" and a "persistent assault" on civil servants.

The House Science Committee's oversight role extends to the national laboratories, facilities like Oak Ridge, Argonne, and Lawrence Berkeley, where workforce reductions can have lasting effects on research capacity that a budget number alone doesn't capture. The DOE FY2027 budget hearing gives members a formal opportunity to press on whether the department can execute its stated priorities with a diminished workforce.

Worth Noting

Rep. Brian Babin (R-TX) chairs the committee, with Rep. Zoe Lofgren (D-CA) serving as ranking member. Rep. Chuck Fleischmann (R-TN), whose district includes Oak Ridge National Laboratory and significant NNSA infrastructure, is a member to watch on the nuclear spending provisions. On the Democratic side, members including Reps. Haley Stevens, Deborah Ross, and Suzanne Bonamici have been vocal on science funding and clean energy investment.

The Bottom Line

The full budget justification documents were published on April 3, 2026, giving members roughly two months to prepare for this congressional energy hearing. A Congressional Research Service report on NNSA FY2027 funding and policy issues has also been circulated, providing additional analytical grounding for the nuclear weapons spending debate.

The hearing will take place against a broader federal energy appropriations backdrop in which the gap between what the administration is requesting and what Congress ultimately enacts remains unresolved. The House Science Committee's review adds another data point to that ongoing negotiation.
