The Blackout, Renewables and the Age of Distrust

I am writing this note from a high-speed train on my way back to Madrid. Just a few days ago, I was one of the thousands of passengers whose plans were disrupted by a massive blackout. In moments like these, when technology suddenly fails, we become aware of how deeply our daily lives depend on complex energy systems.

Power outages immediately spark questions. What happened? Who is responsible? Could it have been prevented? In the public debate that follows, explanations often compete with speculation, and uncertainty easily turns into distrust.

In recent years, the rapid expansion of renewable energy has become one of the central pillars of the global energy transition. Solar, wind, and other clean technologies are essential to reduce greenhouse gas emissions and combat climate change. However, moments of crisis—such as large-scale blackouts—can quickly fuel narratives that question their reliability.

These debates are rarely purely technical. They are also political, social, and cultural. In a context of growing polarization and digital information flows, public perception can shift rapidly. A complex technical incident may be simplified into a political argument about the supposed risks of renewable energy.

Yet energy systems are among the most complex infrastructures societies operate. Blackouts can result from a wide variety of factors, including network failures, operational decisions, weather conditions, cyber risks, or simply the inherent fragility of interconnected systems.

The challenge, therefore, is not to abandon the energy transition but to strengthen it. This requires better communication with citizens, greater transparency in the management of energy systems, and stronger institutional capacity to explain and manage crises.

If the energy transition is to succeed, it must not only be technologically viable but also socially legitimate. In other words, it must build trust.

And trust, in the age of complex technological systems, may be as important as electricity itself.
