A few months after a historic power outage plunged part of Europe into darkness, Spain faces a harsh reality: its energy transition, previously touted as exemplary, reveals troubling flaws. Behind an official discourse that carefully avoids blaming renewable energies, the concrete decisions made by the authorities betray a barely concealed admission.
### Gas Takes Control
According to data reported by Bloomberg, gas consumption for electricity production surged by 41% in the first half of 2025. This remarkable increase is not due to an exceptional demand but rather an urgent need to stabilize a weakened grid. The cause: the massive outage in April, one of the most severe Europe has experienced in recent decades, occurred while renewable energies—primarily wind and solar—were providing a significant portion of the production.
In light of the network imbalances and risks of collapse, Spanish authorities have discreetly shifted their energy strategy, reactivating gas plants to compensate for the intermittency of renewables. This decision starkly contrasts with the official narrative, which continues to focus on decarbonization.
### Political Silence, Technical Realities
Since the blackout, Spanish officials have carefully avoided blaming renewable sources. However, behind the scenes, the adjustments are evident: a resurgence of fossil fuels, investments in gas-based production infrastructure, and the pause of several green interconnection projects.
This cautious communication reflects the authorities’ embarrassment in the face of a public increasingly attuned to climate issues. Acknowledging that renewables contributed to a system failure would undermine a cornerstone of the government’s ecological discourse.
### An Energy Dilemma
Spain, like many European countries, has committed to a rapid transition to clean energy. However, the April outage revealed what many experts feared: without a sufficiently flexible grid and effective storage solutions, the intermittency of renewables can become a vulnerability.
The increase in gas consumption thus appears to be a short-term solution aimed at ensuring supply stability. A pragmatic choice, yet it contradicts emissions reduction goals.
