ChatGPT's take on federal clean energy funding:
The federal government is not eliminating all clean-energy funding. It is shifting from "decarbonization-first" technologies (wind, solar, EVs) toward technologies that can be framed as energy security, grid reliability, industrial competitiveness, defense readiness, and domestic manufacturing.
For startup founders, I would think about the landscape this way:
Technologies currently facing strong headwinds
Solar
Utility-scale and residential solar incentives have been reduced or accelerated toward sunset. Tax credits that were expected to last much longer are being phased out much sooner than originally envisioned.
Wind
Wind appears to be the least-favored major generation technology in the current federal environment. Proposed legislation phases down incentives rapidly and administrative actions have created additional uncertainty.
Electric Vehicles
EV tax credits have been curtailed substantially, including consumer and commercial vehicle incentives.
Building Electrification
Heat pumps, home-efficiency programs, and residential clean-energy incentives have seen significant reductions.
Technologies that appear relatively well-positioned
Advanced Nuclear Fission
This is probably the biggest winner.
The Department of Energy is actively supporting advanced reactors and small modular reactors (SMRs). DOE's Advanced Reactor Demonstration Program continues to fund projects from companies such as TerraPower, X-energy, and Kairos Power. New initiatives are opening federal sites for reactor demonstrations and commercialization.
For founders, opportunities include:
- Advanced reactor components
- Nuclear fuels
- Nuclear cybersecurity
- Digital twins
- Licensing support software
- Workforce development
- Nuclear supply chain technologies
- Geothermal
Geothermal has emerged as one of the administration's preferred clean-energy technologies because it provides firm, dispatchable power.
Congressional proposals have generally preserved geothermal incentives longer than wind and solar incentives.
Interesting startup areas:
- Enhanced geothermal systems (EGS)
- Closed-loop geothermal
- Subsurface imaging
- Drilling technology
- Geothermal heat networks
- Grid-Scale Energy Storage
- Battery storage remains attractive because it supports grid reliability and national security.
Even where renewable incentives are reduced, storage often remains valuable because utilities and data centers need dispatchable power. DOE's Office of Electricity and grid modernization programs continue to support storage-related technologies.
Potential startup areas:
- Long-duration storage
- Grid software
- Battery management systems
- Fire prevention and safety
- Battery recycling
- Domestic supply chains
- Pumped Storage Hydropower
Not glamorous, but viewed favorably because it provides long-duration grid reliability.
Hydropower generally survives policy changes better than wind and solar because it is considered firm generation. Congressional proposals have specifically treated hydropower more favorably.
Critical Minerals
This is a huge area.
The administration strongly supports domestic production of:
- Lithium
- Graphite
- Rare earths
- Nickel
- Copper
Many DOE and Department of Defense programs support these supply chains.
Fusion: a nuanced picture
The DOE continues to fund fusion energy research through its Fusion Energy Sciences program. There is growing interest in fusion because of its potential as an ultra-high-density baseload power source and because of competition with China.
However, most fusion startups are still too far from commercialization for many university incubators and angel investors. I would view fusion as:
- Excellent for deep-tech venture capital
- Excellent for national laboratory partnerships
- Difficult for typical startup accelerators
- Long timelines (often 10–20+ years)
- The sleeper opportunity: Data Center Energy
If I were advising clean-energy startups today, I would pay special attention to AI-driven electricity demand.
The explosion of AI and data centers is changing the political conversation around energy. Technologies that can provide reliable power to data centers are attracting attention across party lines.
This creates opportunities in:
- Microgrids
- Behind-the-meter generation
- Long-duration storage
- Advanced nuclear
- Geothermal
- Grid optimization software
- Demand-response technologies
Where I would steer a clean-energy startup in 2026
If a founder asked me where federal support is strongest today, I would rank the sectors roughly as:
1. Advanced nuclear fission
2. Grid modernization and transmission
3. Energy storage (especially long-duration)
4. Geothermal
5. Critical minerals and domestic supply chains
6. Hydropower / pumped storage
7. Fusion (long-term)
8. Carbon management and industrial decarbonization
9. Solar
10. Wind
11. EVs
The common theme is that Washington's current priorities are energy abundance, grid reliability, AI power demand, domestic manufacturing, national security, and competition with China. Startups that position themselves around those themes generally have a much easier funding story today than startups whose primary value proposition is carbon reduction.
For the founders you're coaching, I would also remind them that federal grants are only one piece of the picture. Utilities, independent system operators, defense agencies, data-center developers, and corporate buyers are increasingly important sources of non-dilutive funding and pilot opportunities, sometimes more attractive than DOE grants alone.
One thing I would add for the founders you coach is that federal funding priorities often change faster than underlying market needs.
When I evaluate clean-energy startups today, I increasingly separate two questions:
- Can this company win a grant?
- Will customers actually pay for it?
A few years ago, many startups could answer "yes" to the first question and postpone the second. That is becoming much harder.
For example:
A startup developing software that helps utilities manage battery storage may have a stronger long-term business than a startup developing another battery chemistry that depends heavily on federal grants.
A geothermal drilling technology that lowers drilling costs by 30% may attract customers regardless of who occupies the White House.
A company helping data centers reduce power consumption by 10% may have a clearer path to revenue than a company focused primarily on carbon accounting.
The other trend I am watching is the convergence of energy, AI, and national security. Those three themes currently have strong political support across much of the spectrum. Startups that can credibly position themselves at the intersection of those themes often have access to a wider range of funding sources:
- DOE
- Department of Defense
- National laboratories
- Utilities
- Data center operators
- Corporate strategic investors
- Venture capital
As someone coaching startups, you may find it useful to encourage founders to replace the phrase:
"We reduce carbon emissions."
with:
"We reduce operating costs, improve reliability, strengthen domestic supply chains, increase energy security, and happen to reduce carbon emissions."
The underlying technology may be identical, but the second framing resonates with a much broader set of customers, investors, and government programs in the current environment.
One final observation: among all the clean-energy sectors, grid modernization may be the least glamorous and one of the largest opportunities. The U.S. can build all the generation it wants, but without better transmission, distribution management, interconnection processes, forecasting, grid software, and storage integration, much of that capacity cannot be fully utilized. Founders often chase breakthrough generation technologies while overlooking the enormous value that can be created by making the grid smarter and more efficient.
It's not just "What technology is exciting?" but "Where are customers, investors, and policymakers actually directing resources?" Those are often very different answers.
