The erasure of the word “Renewable” from the National Renewable Energy Laboratory marks the end—or hopefully just an interruption—of a long and consequential chapter in energy history. Renaming it as the National Laboratory of the Rockies doesn’t change the buildings in Golden or the servers in ESIF or the unfinished research notes on desks, but it closes the book, at least temporarily, on the mission the lab was created to serve. It feels less like an administrative update and more like a declaration that the domestic purpose of the institution has ended. The laboratory’s name once announced the direction a nation intended to travel. Now it signals retreat. The irony is that the global energy transition NREL helped shape is well underway, unstoppable, and accelerating in places that still take the future seriously.
NREL was born of insecurity and ambition. In the late 1970s, the Solar Energy Research Institute emerged from the oil shocks with a clear mandate: figure out how to break the cycle of fossil vulnerability through technology. By 1991, when it became the National Renewable Energy Laboratory, the scope had widened from solar panels to full-spectrum clean energy. The United States, still the world’s scientific superpower, built an institution meant to lead the next energy era rather than cling to the last one. This mission guided decades of work that shaped global markets, technology pathways, and public policy frameworks. It also gave the world a measurement standard for progress in solar energy, a language for modeling high-renewable grids, and validation tools that helped entire industries converge on best practices. The goal was always simple: make clean energy cheaper, better, and abundant. In that mission, NREL succeeded.
The laboratory’s core contributions are woven into modern energy systems. An artifact of its influence is the solar cell efficiency chart, a single graphic that became the scoreboard of energy transformation. Every solar company, every research lab, and every analyst has relied on its structure and classification, and almost every major breakthrough in PV efficiency passed through NREL’s verification protocols before the world accepted it. That chart wasn’t just a record of scientific progress but an organizing principle for an industry that now dominates global electricity investment.
Wind owes a similar debt. NREL’s work on aero-servo-elastic modeling, siting tools, and turbine performance frameworks became part of the design DNA of the global OEM fleet. Their work didn’t sit in reports; it lived inside simulation packages and toolchains embedded across the industry. Their contributions helped make modern wind farms quieter, more powerful, and far more reliable than their predecessors. Without their modelling tools, the cost curves of wind would have bent more slowly, and the institutional learning that now makes turbines easier to deploy would have taken longer to form.
Perhaps the most under-appreciated contribution was NREL’s approach to whole-system analysis. Long before utilities or grid operators accepted that renewables would reach majority shares of generation, NREL was modeling what those grids would look like. Their scenarios and integration studies underpinned the policies of several states and informed international work that now guides Europe, China, India, and many others. The Energy Systems Integration Facility was the hardware realization of this worldview, allowing real-time testing of inverters, storage, and distribution equipment under conditions approaching real-world stress. This was where the future grid was rehearsed before being built.
The Annual Technology Baseline became another quiet global institution. Utilities, governments, researchers, developers, and analysts all built their forecasts and investment plans around it. It standardized cost and performance assumptions for solar, wind, geothermal, storage, and more. It gave the global energy sector a shared reference point and prevented every study from reinventing cost curves from scratch. The ATB is embedded in almost every modern decarbonization model, including international scenarios developed by organizations like the IEA and hundreds of academic institutions. Its influence is nearly invisible because it is so widely internalized.
Geothermal benefited from the same rigor. NREL helped shape early enhanced-geothermal-systems modeling, organic Rankine cycle (ORC) optimization, and the mapping and risk-reduction frameworks that led to the modern enhanced geothermal systems (EGS) moment in the sun, for what that’s worth. Their contributions informed the DOE’s FORGE initiative and brought coherence to subsurface modelling approaches that had once been scattered and inconsistent. NREL studied and tried many things that didn’t pan out. ORC was one that panned out, enabling broader basic geothermal generation to expand. EGS might be, although I’m skeptical.
Beyond the central pillars, NREL created and maintained a suite of tools so widely used that many people forget where they came from. PVWatts, SAM, ReEDS, BEopt, OpenStudio, and other modeling environments have shaped solar development, building performance, utility planning, and city-level energy strategies. These tools democratized modeling capacity and let thousands of engineers, planners, and analysts do professional-grade work without a proprietary software budget. For an institution focused on enabling markets, this was a profound form of influence.
All of this work now continues, but not in the United States in the way it once did. Other countries and institutions have already absorbed the intellectual momentum. China’s solar manufacturing juggernaut refined its processes using principles NREL validated. Europe’s grid integration strategies in part follow the analytical paths NREL established. Universities in Asia, Europe, and South America have built renewable-energy curriculum structures that parallel NREL’s modeling logic. Private-sector research labs in batteries, hydrogen alternatives, geothermal systems, and industrial decarbonization now stand on conceptual foundations that came from Golden, even if they never say so.
The decision to erase “Renewable” from the name is less an act of strategic repositioning and more a gesture from a fading energy paradigm grasping for relevance. Fossil incumbency has been losing on price, on technology, on scalability, and on public sentiment. When systems fall behind, they tend to reach backwards, not forwards. Renaming a research institution cannot restore the economics of the past, nor revive the idea that hydrocarbons are destiny. The learning curves that NREL helped document are now so steep and global that no single bureaucracy can reverse them. The name change is a rear guard maneuver: the last flicker of an order that survived by habit more than necessity.
The United States loses something real in this moment. It loses a research compass point that kept its energy transition grounded in evidence. It loses its most credible source of long-term cost and performance data. It loses a central gathering place for expertise that understood renewables not as boutique technologies but as the core of a modern power system. Most importantly, it loses a mission that once aligned the country’s scientific talent with its long-term interests. Other nations will continue the work, but the center of gravity has shifted.
The broader energy transition continues regardless. Wind and solar dominate new generation investment globally. Batteries are eating the peak-power and flexibility markets. Heat pumps are reshaping heating demand. Geothermal is re-emerging in new forms, although not likely the most hyped ones. Transmission expansion and digitalization are accelerating. The systems NREL helped design are now too economically strong and too globally distributed to be halted by a naming ceremony. Energy transitions do not wait for political coherence.
In moments like this, it is important to acknowledge the people who made NREL what it was. Thousands of researchers, engineers, technicians, modelers, administrators, and students contributed to an institution that punched far above its weight. Their work shaped the modern energy landscape and helped push entire industries out of the speculative phase and into maturity. I’ve been privileged to collaborate with several of them. Their contributions were not in vain. They built a scaffolding the world now stands on and their influence will continue long after the bureaucratic paint dries on the laboratory sign. The United States will eventually return to rational energy policy, because economics, physics, and global competition always pull nations back toward reality.
For now, the institution that carried the renewable banner for nearly half a century has been symbolically laid to rest. But its body of work is alive in every solar factory, every modern wind turbine, every renewable-heavy grid study, and every national decarbonization plan built on shared assumptions. The name may change, but the world that NREL helped build is fully formed and moving forward. History will remember the contributions far more clearly than the rebranding.
