Renewable Energy Through the Lens of National Culture: Comparing Spain and Japan
Beyond Geography: Why Spain Moved Faster on Renewables
Spain’s renewable energy expansion is often explained through geography. The country combines three unusually favorable conditions for utility-scale solar deployment: high solar irradiation, relatively low land-use competition in semi-arid regions, and proximity to major demand centers and transmission infrastructure. Together, these factors created one of the world’s rare “sweet spots” for large-scale renewable deployment.
But geography alone does not fully explain Spain’s trajectory.
After several field studies conducted across Spain, we increasingly felt that another factor may also matter: national temperament. Renewable energy systems built around solar and wind inherently require societies to tolerate volatility, uncertainty, and operational imperfection. In that sense, the energy transition is not only a technological transformation; it is also a cultural one.
Renewable Energy Requires a Tolerance for Risk
Unlike thermal or nuclear generation, solar and wind are governed by weather patterns rather than engineering schedules. Their challenge lies not only in output variability itself, but also in forecast uncertainty — a double layer of volatility that power systems must continuously absorb.
Yet Spain has pushed variable renewable penetration to levels where, during certain hours, wind and solar together approach the majority of national electricity demand. Doing so on a grid not originally designed for such conditions requires more than technology and investment. It requires a societal willingness to operate closer to uncertainty.
That willingness appears particularly visible in Spain.
A “Build First, Improve Later” Mindset
One striking feature of Spain’s energy transition is its apparent comfort with experimentation.
Where countries such as Japan — and, to a degree, Germany — often seek institutional completeness before implementation, Spain has at times appeared more willing to move forward first and refine later. Problems are treated not necessarily as reasons to stop, but as engineering and governance challenges to be progressively solved.
This mindset became especially visible after the large-scale Iberian blackout of 2025. The event triggered intense political and technical debate over grid inertia, voltage management, balancing capability, and renewable integration. Yet remarkably, the broader direction of policy did not fundamentally reverse.
The dominant response was not “renewables went too far,” but rather “the system must evolve further.” Investments in storage, transmission reinforcement, grid flexibility, and system operations accelerated rather than retreated.
Spain Was Also a First Mover in Feed-in Tariffs
Spain’s willingness to experiment was visible much earlier in policy design itself.
Germany pioneered modern feed-in tariffs through the 1991 Electricity Feed-in Act and the 2000 Renewable Energy Sources Act (EEG), offering highly attractive long-term fixed-price contracts for renewable generation. Early rooftop solar tariffs exceeded €0.50/kWh — extraordinarily generous for the time.
Spain followed aggressively. Under the 2004 framework and especially the 2007 RD661/2007 decree, solar FITs exceeded €0.40/kWh while benefiting from far superior solar conditions than Germany. Capital flooded into the market, and Spain experienced one of the fastest solar expansions in the world during the late 2000s.
The boom, however, produced severe side effects. Financial pressures, tariff deficits, and the aftermath of the global financial crisis forced the Spanish government into abrupt policy reversals after 2010, including retroactive cuts to renewable subsidies — one of the most controversial episodes in renewable policy history.
Under many political cultures, such an experience might have permanently discredited renewable energy itself. In Spain, it did not.
The country eventually resumed its position as one of Europe’s leading renewable markets, expanding not only solar and wind, but also storage, hydrogen, and transmission infrastructure. In retrospect, Spain’s trajectory reflects a distinctly high-risk, high-adaptation model: move early, adjust aggressively when necessary, but maintain strategic direction.
Japan’s More Cautious Institutional Culture
Japan later adopted its own FIT system in 2012, heavily influenced by the German and Spanish models. Following the Fukushima nuclear accident, the country introduced one of the world’s highest utility-scale solar tariffs at ¥42/kWh, triggering a rapid nationwide expansion of mega-solar projects.
Yet Japan’s social response has evolved differently.
Large-scale renewable deployment has increasingly generated backlash over landscape impacts, deforestation, disaster risk, and tensions with local communities. In parts of Japanese society, “renewables” themselves have gradually acquired negative political connotations.
This may partly reflect differences in institutional culture.
Japan possesses enormous strengths: precision, reliability, social order, and an extraordinary capacity for risk minimization. But that same culture can also produce a strong aversion to failure. The Japanese proverb “crossing a stone bridge only after tapping it repeatedly” captures this instinct well. Even when the bridge is made of stone, caution comes first.
Spain, by contrast — perhaps unfairly simplified, but nevertheless perceptibly so — often feels less “deduction-oriented” and more “addition-oriented”: rewarding initiative first, correcting imperfections later.
The Energy Transition Is Also a Cultural Transition
Of course, no nation can be reduced to stereotypes, and Spain faces its own political, economic, and technical constraints. Yet while traveling through the country, one cannot help but sense a certain societal elasticity — a willingness to absorb disruption, tolerate imperfection, and continue moving forward despite setbacks.
That cultural flexibility may not fully explain Spain’s renewable success. But it may help explain why the country has been willing to push further, faster, and more experimentally than many others.
In the end, the energy transition may depend not only on sunlight, land, grids, and capital — but also on how societies perceive risk, failure, and progress itself.
