Agency: U.S. Department of Energy Role: Press Secretary and Chief Spokesperson (January 2025 – present) Severity: P2

Bio and Background {#bio}

Ben Dietderich serves as the Press Secretary and Chief Spokesperson for the U.S. Department of Energy under Secretary Chris Wright. He was named to the position in the initial wave of senior staff appointments announced February 13, 2025.

Education: Dietderich is a graduate of Hillsdale College, earning a Bachelor of Arts degree between 2016 and 2020. Hillsdale College is a conservative liberal arts institution that explicitly rejects federal funding to maintain ideological independence; it has been a significant pipeline into Trump administration staffing. While a student, Dietderich wrote for the Hillsdale Collegian student newspaper and produced content for the Heartland Institute, a Chicago-based think tank that disputes climate change consensus and advocates against environmental regulation.

Pre-DOE career: Dietderich’s LinkedIn profile lists his DOE appointment as his first major professional position; his prior experience appears to be primarily academic and student journalism. He graduated from Hillsdale in 2020 and entered the DOE role in early 2025, suggesting employment in the intervening period that is not prominently documented in available public records. His connection to the Heartland Institute as a Hillsdale student is documented.

Role and Communications Function {#role}

As Press Secretary and Chief Spokesperson, Dietderich is the primary public face and media point of contact for the Department of Energy. He handles media inquiries, issues official departmental statements, and represents DOE’s communications posture on all major policy areas. He works alongside Andrea Woods, Deputy Director of the Office of Public Affairs.

The DOE under Secretary Chris Wright is a central agency for implementing Trump’s “energy dominance” agenda, which includes:

• LNG export expansion: Accelerating liquefied natural gas export approvals
• AI infrastructure power: Providing federal support for data center energy buildout
• Nuclear energy expansion: Funding small modular reactors and next-generation nuclear
• Fossil fuel rehabilitation: Reversing Biden-era restrictions on coal, oil, and gas
• Clean energy pullback: Cancelling or restructuring clean energy grants from the Biden era
• Regulatory rollback: Reducing environmental and efficiency standards

Dietderich’s job is to publicly defend and explain each of these priorities in media interactions.

The State Department has confirmed that Dietderich moderated questions during a digital press briefing with Secretary Wright, indicating he also plays a diplomatic communications support role. (State Department briefing, archived)

Messaging Strategy {#messaging-strategy}

Dietderich’s documented public communications consistently follow a set of core DOE messaging pillars under the Wright-Trump framework:

1. “Energy dominance” framing: All major energy policies are characterized as advancing American energy dominance, economic growth, and national security rather than in climate terms.

1. AI + nuclear as unified narrative: DOE messaging under Dietderich frames AI infrastructure power demands and nuclear energy expansion as complementary priorities — implying a need for baseload reliable power that renewable energy cannot provide.

1. Anti-renewable grid reliability claims: Dietderich has made attributable statements characterizing wind and solar as increasing costs and reducing grid reliability, which fact-checkers and energy economists have disputed.

1. Reframing Biden-era programs as misaligned: When defending grant cancellations or regulatory rollbacks, Dietderich characterizes prior clean energy investments as having “missed milestones” or being misaligned with administration priorities rather than ideologically opposed to renewables.

1. Denying language management: When confronted with evidence of climate vocabulary restrictions in DOE communications, Dietderich has denied formal directives exist.

Significant Public Statements {#statements}

Wind and solar grid reliability (E&E News/Politico, 2025): DOE spokesperson Ben Dietderich told E&E News that wind and solar have “only increased costs and made the energy grid less reliable” and that “the production of dispatchable energy sources such as coal, oil, gas and nuclear have been hindered by regulations, costly permitting burdens, and environmental activism.” These statements were included in an E&E News fact-check of claims by Secretary Chris Wright on energy. Energy economists and grid analysts have disputed the broad characterization that wind and solar universally increase costs and reduce reliability, noting wide regional variation and the significant cost declines in renewable generation. (E&E News, “Fact-checking Chris Wright on energy”)

Clean energy grant cancellations defense (E&E News, 2025): When the Trump administration cancelled grants for several U.S. battery-related energy projects, Dietderich told E&E News that the projects “had missed milestones.” This framing placed responsibility on grantees rather than acknowledging the administration’s policy opposition to clean energy investment. (Industrial Info/E&E News reporting)

Court ruling on clean energy grant cancellation (Anadolu Agency, 2025): When a U.S. judge blocked the Trump administration’s move to cancel $27.5 million in clean-energy grants, Dietderich said the agency “disagreed with the ruling” and defended the review process, saying the grants were under appropriate review. (Anadolu Agency reporting)

Climate word ban denial (Politico/NPR/OPB, September 30, 2025): After POLITICO/E&E News and NPR obtained internal DOE guidance directing employees in the Office of Energy Efficiency and Renewable Energy (EERE) to avoid using approximately a dozen terms — including “climate change,” “emissions,” “decarbonization,” “energy transition,” “sustainability/sustainable,” and “‘clean’ or ‘dirty’ energy” — Dietderich issued a flat denial: “There is no directive at the Energy Department instructing employees to avoid using phrases such as ‘climate change’ or ’emissions.'” He added that “President Trump and Secretary Wright remain committed to transparency and fostering an open, honest dialogue about climate science.” This denial was issued simultaneously with multiple news organizations publishing documentation of the guidance. (POLITICO/E&E News, Politico Pro, September 30, 2025; OPB/NPR, September 30, 2025)

Wright “wrong direction” video editing (News4Jax/AP, April 2026): After Secretary Wright appeared to say the U.S. was heading “in the wrong direction” on energy policy — a comment that surfaced in video — and the DOE’s YouTube account posted excerpts of Wright’s speech that excluded the phrase, Dietderich “denied any deliberate editing on the department’s YouTube account, saying the excerpts were presented” in appropriate context. (News4Jax/AP, April 14, 2026)

EIA Annual Energy Outlook statement (DOE, 2025): DOE issued a statement, published directly by the department and attributed through spokesperson channels, framing the EIA’s Annual Energy Outlook as evidence for “greater consumer choice” and the need for “coal, natural gas and nuclear energy” under the administration’s direction. (DOE.gov)

US-UAE energy collaboration (GCC Business Watch, 2025-2026): Dietderich served as U.S. spokesperson at international engagements, stating that the U.S. “sees great potential to expand US-UAE energy collaboration” — part of the administration’s international energy diplomacy aligned with fossil fuel export expansion. (GCC Business Watch)

Controversies {#controversies}

Climate word ban denial vs. documented guidance: The most significant documented controversy involving Dietderich is his September 2025 flat denial that any directive existed to avoid climate-related terminology at DOE, issued at the same time that multiple major news organizations (POLITICO, NPR, The Guardian) published documentation of EERE internal guidance containing precisely such a list. The guidance, reportedly sent to EERE employees and obtained by multiple outlets, instructed staff to “remove or rephrase” approximately a dozen terms before content went through a “content approval process” and stated: “Please ensure that every member of your team is aware that this is the latest list of words to avoid.” Dietderich’s denial is directly contradicted by the documented guidance. (OPB/NPR, September 30, 2025; POLITICO, September 28, 2025; Columbia Law School Climate summary)

Grid reliability framing: Dietderich’s statement that wind and solar have “only increased costs and made the energy grid less reliable” is a sweeping characterization that energy economists and grid operators have challenged as oversimplified. The LCOE (levelized cost of energy) for wind and solar has fallen dramatically, and grid reliability concerns are typically more complex and region-specific than a blanket anti-renewable framing suggests. E&E News included this statement in a fact-check article on Secretary Wright’s energy claims. (E&E News)

Hillsdale College / Heartland Institute background: Dietderich’s documented ideological formation at Hillsdale College and his student contributions to the Heartland Institute — which has a documented history of producing climate disinformation — are relevant context for assessing whether his communications function serves science-based transparency or ideological advocacy. This is not an accountability finding per se but establishes a documented pipeline from climate-skeptic intellectual institutions to an official government communications role.
