With a remarkably candid statement, the French Minister of Energy Agnès Pannier-Runacher identified a central problem of the ecological transformation. Regarding the energy renovation of schools, she stated: “The problem is not necessarily a matter of financial resources, but also a matter of structuring the sector – that is, the ability to carry out the work within the given time.” This statement points to a development that goes far beyond individual school buildings. France increasingly encounters the limits of its practical implementation capacity in the energy transition.
The bottleneck lies at the construction sites
In the political debate, the question of investment amounts was central for a long time. Billion-euro programs for ecological transformation were seen as the decisive leverage to achieve European climate goals. But meanwhile, it has become clear: public funds alone no longer guarantee rapid execution.
Especially in the energy renovation of public buildings, a structural problem is revealed. France does have incentive programs, state aid, and European funding options. At the same time, many places lack companies that can actually carry out the work.
Energy modernization of schools belongs to the technically most demanding sectors of construction engineering. Insulation, replacement of windows, conversion of heating systems, ventilation systems, or roof renovations must be coordinated. In addition, new requirements for thermal protection and energy efficiency are emerging. However, many municipalities report long waiting times, a lack of specialized companies, and tenders to which hardly any companies respond.
The situation is particularly difficult in rural areas. Specialized craft businesses or engineering firms with sufficient capacity are often missing there. At the same time, the pressure on municipalities to modernize their buildings more quickly is increasing.
A shortage of qualified skilled workers
The problem is primarily due to a shortage of skilled personnel. France has been struggling for years with recruitment issues in the construction and craft sectors. Many professions are seen as physically demanding and socially unattractive. Numerous companies no longer find sufficiently qualified workers.
Energy renovation increasingly requires specialized skills. Modern buildings must not only be insulated but also designed with technical intelligence. Mistakes can have serious consequences. Poor ventilation can lead to moisture problems, insufficient summer heat protection to overheated classrooms. Moreover, the actual energy savings often fall short of theoretical calculations if the work is poorly coordinated.
This shifts the debate from purely financing to the industrial performance capacity of the country. France not only needs investments but also a functional value chain: training centers, craft businesses, engineers, material suppliers, and local construction companies.
The problem of tight time windows
An organizational factor is added to this, which Pannier-Runacher explicitly mentions: the timely execution of the work. Schools can only be renovated to a limited extent during the ongoing school period. Many larger measures therefore have to take place during the summer holidays.
This drastically reduces the available time windows. Municipalities therefore often try to carry out as much work as possible simultaneously within a few weeks. For the construction sector, this means enormous peak loads. Even if sufficient funds were available, thousands of construction sites cannot be handled in parallel within a very short time.
This problem is expected to worsen further in the coming years. France has set ambitious climate goals and is under European pressure to significantly reduce the energy consumption of buildings. Public buildings play a central role in this, as they account for a significant portion of energy consumption.
Schools as a symbol of the French infrastructure crisis
The discussion is also politically sensitive because many French schools are in poor condition. A large part of the building stock dates from the 1960s and 1970s. At that time, many school complexes were built quickly and cheaply, often with low energy quality.
Today, many facilities suffer from outdated heating systems, poor insulation and insufficient ventilation. The European energy crisis since 2022 has further exacerbated the problems. Numerous municipalities had to bear sharply rising heating costs, while at the same time the pressure on decarbonization increased.
In addition, the importance of heat protection is growing. France has been experiencing more intense heat waves for years. Many school buildings are not prepared for this. Classrooms sometimes become unbearably hot in summer, which is increasingly becoming an educational and health-related issue.
A change in political thinking
Pannier-Runacher’s statement therefore also marks a rhetorical change within the French government. For a long time, politics mainly presented the ecological transformation as a financing issue. Meanwhile, practical feasibility is coming more to the fore.
This concerns not only building renovation. Similar bottlenecks occur in the expansion of renewable energy sources, the electricity grid, or in traffic infrastructure. Everywhere the same question arises: does France have sufficient industrial and personnel capacities to manage the transformation at the intended pace?
The minister thereby indirectly implies that the ecological transformation is less likely to fail due to political objectives than due to the performance level of the real economy. Climate policy is thus entering a new phase: moving away from symbolic announcements, towards questions about productive capacity, training, and organizational efficiency.
It is precisely in this that the greatest challenge of the coming years possibly lies. The energy transition is not only decided in ministries or at international climate conferences. It is also decided on construction sites, in vocational schools, and in the local structures of the trades.
