The California Power System in 2025: How Battery Storage Is Rewriting the Daily Operation of the Electricity Market (I)

The California Power System in 2025: How Battery Storage Is Rewriting the Daily Operation of the Electricity Market (I)

From our European perspective, taking a close look at the day-to-day reality of California’s power system is like observing an open-air laboratory from which to learn, and from which we can anticipate what our own daily life might look like a few years from now. The reason is that, until about five years ago, California’s electricity system had a daily reality very similar to the one we currently have in Spain: a lot of photovoltaic generation and large energy surpluses at midday.

The Relationship Between Electricity Prices and Heatwaves: How Global Warming Is Stress-Testing Europe’s Power System.

The Relationship Between Electricity Prices and Heatwaves: How Global Warming Is Stress-Testing Europe’s Power System.

When we talk about climate change and the sustained rise in global temperatures, the public debate often focuses on environmental consequences or on the need to reduce greenhouse gas emissions. Yet there is a fundamental aspect that is rarely discussed and is becoming increasingly relevant: global warming and extreme temperatures have a very negative impact on the electricity generation capacity of nuclear power plants, cogeneration plants, and combined-cycle plants, which, in the current context, continue to be one of the essential pillars of electricity generation systems.

The Energy Transition in the Mediterranean Maritime Sector.

This week, as Second Vice President of ANBE (National Association for Electric Boats), I had the opportunity to take part in the session “Navigating Transformation in the Mediterranean Maritime Sector”, held within the MedaLogistics conference series organized by ASCAME (Association of Mediterranean Chambers of Commerce and Industry) as part of SIL Barcelona 2025.

The Energy Consumption of Artificial Intelligence: A Global Challenge.

The Energy Consumption of Artificial Intelligence: A Global Challenge.

Article available in: CAT EN FR ES A few weeks ago, I had the opportunity to attend a lecture delivered by industrial engineer Mr. Joan Vila, CEO of LC Paper Group and a sustainability expert at the Institut d’Estudis Catalans. In his presentation, Joan Vila structured his talk around three main themes: energy, raw materials, and economic crises. As he highlighted, these three areas are profoundly interconnected and must be addressed to understand our global challenges. During the conference, numerous…

Energy Transition in Catalonia: Insights into 34 Years of CO₂e Emissions.

Energy Transition in Catalonia: Insights into 34 Years of CO₂e Emissions.

Article available in: CAT EN FR ES The other day, I came across a news article that caught my attention. The University of Potsdam published the results of an intriguing study from an industrial and environmental perspective in the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS). After analyzing data from 1,500 regions worldwide over the past 30 years, the researchers concluded that 30% of these regions managed to reduce carbon emissions while maintaining sustained economic growth….

The basic geometry of Gothic: the vesica piscis.

The basic geometry of Gothic: the vesica piscis.

Gothic cathedrals synthesize perfectly human ingenuity, the beauty of geometry, and spirituality. They are a testament to an era when knowledge and faith merged to create, through architecture, a connection between the earthly world and the celestial realm. When we step into these spaces, we immerse ourselves in a world where every proportion, every angle, and every shape is part of a geometric language that expresses the search for infinity and the desire to reach heaven. Everything seems designed to…

The Legacy of “Born in the USA” on its 40th Anniversary

The Legacy of “Born in the USA” on its 40th Anniversary

In 1984, when Bruce Springsteen released the album “Born in the USA,” the view of the United States from Europe was that of a powerful country, mainly because the most media-driven aspects of American culture and industry were part of everyday media: Reagan-era politics, the supremacy of the Lakers and Celtics in the NBA, the 1984 Los Angeles Olympics, Hollywood films of the time, or the birth of Apple’s Macintosh and Microsoft’s Windows, are some of the examples that everyone…
