Who Powers the Transition?

Renewable Energy, Investment, and the Aviation Systems

Aviation’s path beyond net zero relies less on technological leaps and more on aligning energy systems, institutions, and investments with the true factors that will determine the sector’s sustainability.

At a sustainability session during the annual conference hosted by Women in Aviation International in Dallas, Texas, aviation’s transition seemed well defined at first. Industry leaders spoke in familiar terms of process efficiency, renewable energy, advanced technologies, and market-based measures. These categories now frame how aviation describes its path toward net zero. However, as the conversation shifted from high-level commitments to functional realities, a different question began to take shape.

The key question is no longer whether aviation can decarbonize, but whether supporting systems are advancing quickly enough to enable that transition.

This distinction is important because it shifts focus from aircraft and fuels to the underlying systems that enable aviation, such as energy infrastructure, regulatory bodies, investment climate, and supply chains.

From Technology to Systems

Electric aviation offers a useful entry point into this shift. Though often seen as a technological innovation, its development moves along regulatory pathways, not just technical milestones. Companies like BETA Technologies advance aircraft through staged Federal Aviation Administration (FAA) certification. They start by integrating electric propulsion systems into existing airframes, then progress to fully electric designs. This incremental approach shows a broader reality. Innovation in aviation depends not only on engineering capability but also on certification frameworks, safety standards, and institutional readiness. Technology advances within governance systems.
Sustainable Aviation Fuel (SAF) faces similar challenges. While SAF is essential in the near term, its growth is limited by cost, feedstock availability, and supply chain constraints. The International Energy Agency (IEA) reports that SAF accounts for less than 0.1% of global aviation fuel consumption, highlighting the significant progress still required.

Policy differences are also significant. Conference discussions highlighted that Europe offers stronger regulatory clarity than the United States, especially regarding SAF. The European Union’s ReFuelEU Aviation framework establishes binding targets for SAF adoption at EU airports, providing clear long-term signals for suppliers and investors. In contrast, the United States relies on a mix of incentives and programs rather than a unified regulatory framework. This distinction is important because low-carbon transitions require clear policies to attract investment and achieve scale. Viewed together, these examples underscore a deeper conclusion: aviation’s future depends not just on adopting new technologies but on coordinating a broader transition in energy systems, institutions, and infrastructure.

Airports as Energy Systems.

That transition becomes more apparent at the infrastructure level.

Airports were mainly seen as transit points. Now, they are increasingly operating as energy systems. Electrification brings new layers of demand: electric ground support equipment, building systems, charging infrastructure, and digital energy management platforms. These systems are added to infrastructure not designed for sustained high electrical loads.

What is especially useful about the San Francisco International Airport (SFO) example is that it shows both ambition and constraint. SFO’s own distributed energy planning found that 50 megawatts of new solar installations could provide roughly 30% of the airport’s annual grid electricity use. That is a good contribution, but it also makes the larger point. Even a highly proactive airport cannot meet all of its electricity demand through on-site renewable generation alone.

That is where internal grid modernization becomes important. Internal electrical infrastructure is not only a technical issue. It affects resilience during grid stress events, load balancing, the integration of distributed resources, and long-term operating costs. In that sense, airport sustainability is no longer just about efficiency upgrades. It is increasingly about energy governance within complex infrastructure systems. SFO’s public materials on net-zero energy and distributed resources point in exactly that direction

This constraint, however, is not unique to one location; it is structural.

Electrification increases demand in ways that community-based renewables cannot fully absorb. Airports stay part of broader energy networks. They rely on regional grids, transmission, and large energy markets. The line between aviation and energy systems is getting harder to define.

Competing Demand in an Electrifying Economy

The elements shaping aviation are not unique.

Electricity demand is rising as more sectors electrify. Transport, buildings, and digital infrastructure now rely on electric power. Data centers, powered by digital services and artificial intelligence, need continuous electricity and cooling, while transmission build-out is being slowed in many places by rising component prices and supply chain pressures. The result is not a single sectoral challenge, but a convergence of transitions across shared energy systems.

That is why the central challenge is no longer clean energy generation. It is coordination.

If the challenge is systemic, so too are the constraints it creates. Renewable generation can expand faster than infrastructure is upgraded. Technology can move faster than regulation adapts. Investment can target new capacity while underfunding the networks required to support it. This was one of the strongest ideas carried over from my broader research: transitions do not fail only because technology is weak. They also stall when institutions, infrastructure, and financing move at different speeds.

This is why a systems thinking perspective is more important than a technical approach. Aviation’s transition involves energy, infrastructure, governance, and markets. Aircraft readiness, fuel supply, grid capacity, resilience planning, and long-term finance are all interdependent.

Infrastructure in a Geopolitical Economy

These challenges also depend on global conditions. Forums such as the International Federation of Consulting Engineers FIDIC demonstrate how political tensions, supply chain disruptions, and shifting energy strategies are reshaping the financing, design, and delivery of infrastructure.

Electrification depends on globally sourced components, battery materials, grid equipment, and digital systems. These supply chains are exposed to cost volatility, trade trends, and competing national priorities. Infrastructure, in this sense, is not simply technical. It is economically and strategically important.

Who builds the transition?

This brings the focus to a question often missing from discussions of technology and emissions. Who builds the transition?

Electrification is enabled by networks of contractors, suppliers, engineers, and service providers. These networks shape how quickly infrastructure can scale and how resilient it becomes under pressure. Disadvantaged Business Enterprise (DBE) programs, originally designed to expand participation in public contracting, matter here not only as an equity tool but also as part of the structure of supply chains in emerging clean infrastructure markets. That point was largely absent from the aviation conference discussion, but it is increasingly hard to ignore.

A Systems Transition

Participation drives performance. Broader, adaptive supplier systems absorb shocks, meet demand, and enable long-term growth. These capabilities are integral to sustainable and successful transitions. What emerges is not a single narrative, but a set of interdependent systems evolving at different rates.

Technologies advance while infrastructure lags. Governance adapts unevenly, and markets respond to misaligned signals. Aviation’s transition is shaped not only by aircraft, but by the supporting systems.

Electric aviation will likely become more prominent. Sustainable fuels may scale, and renewable energy may expand. However, the success of this transition will depend less on visible technological advances and more on the alignment of energy systems, infrastructure, governance, and investment to support it at scale.

The central question is no longer just how to decarbonize aviation.

It is also about who drives the transition and how the supporting systems are constructed.
