Pedro Prieto – Fragile Electric Grids: Did Renewables Cause the Blackout in Spain?

The Great Simplification
Description
Last week, Europe experienced its worst blackout in living memory, which plunged tens of millions of people across Spain and Portugal into darkness for up to 18 hours. Life screeched to a halt, with trains, traffic lights, ATMs, phone connections, and internet access failing. In the aftermath, many important questions have arisen, including: what caused such a widespread grid failure, and how can Europe and other nations prepare for the next time an event like this happens?
In today’s episode, Nate is joined by Pedro Prieto to discuss the recent blackout in the Iberian Peninsula, exploring its causes, impacts, and the role of renewable energy in the stability of the electric grid. Prieto highlights the societal and infrastructural challenges that his home country faced, emphasizing the need for a balanced approach to energy management, as well as the interconnectedness of energy systems and societal resilience. The discussion delves into the complexities of energy demand and supply, the importance of backup systems, and the future of renewable energy in Spain.
Are developed countries more vulnerable to blackouts than those that are still developing? How does renewable energy act as a double-edged sword, adding stability or fragility to energy infrastructure, depending on how it’s used? How might developed countries learn lessons from this widespread blackout, including policy changes or reducing energy dependence in the face of future energy challenges?

In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
