An update on my May post on Italy's Secret "Cheese Bank" - Global Warming or Lack of Infrastructure?
I saw several stories earlier this week connecting with a post I did in May on Italy's cheese banks and the "threat" of global warming. Then when you get into the stories, the details get more complicated - is this an issue of extreme heat waves (in Italy, a country used to high summer temperatures) or an issue with Europe's aging power system and the challenges of converting from traditional energy sources to meet renewable energy government mandates? As usual, here are some links to consider . . .
As usual, I'm just providing a sampling of the new content - use the links to access the actual sources. I will start with a couple of video clips about the immediate issue, though in both cases they include background on the use of "cheese banks" (in case you didn't read the May 13th post). If you want to look more at lesson plans connecting this to alternative banking examples, you will have to go back to that prior post . . .
The "Bigger Picture" - Is this climate change or antiquated infrastructure (or both)?
I wanted to wrap up this post with a quick look at the "bigger picture" mentioned by a couple of the stories above. While climate change (or at least a very hot summer in Europe) gets the short-term blame, is the issue for cheese banks more about seasonal weather events or a bigger problem with Europe (and North America's) aging power grid and difficulty converting to new renewable forms of energy? Here are four issues to consider:
Outdated Networks and Unprecedented Speed of Updates: Much of Europe's power grid is over 40 years old and designed for centralized fossil-fuel plants, making it ill-suited for decentralized, weather-dependent renewable inputs. On the other hand, proponents argue that forcing a fast update transition was necessary to break fossil-fuel dependence, especially following the 2022 energy crisis triggered by the Russia-Ukraine conflict.
Catch-Up Investment Sometimes Results in Longer Queues for Developers: Grid operators and the European Union are heavily accelerating capital injections, but building new high-voltage power lines takes 7 to 10 years. That has led to wait times of up to 5-10 years for developers to secure grid connections for new solar and wind projects (because private entrepreneurs have moved faster than government spending).
Grid Bottlenecks: For years, experts viewed economics as the main hurdle to scaling clean energy. High costs for wind, solar, heat pumps, and storage dominated the conversation. But now thanks to dramatic cost reductions in renewables and electrification technologies, the challenge is whether energy systems can evolve quickly enough to integrate it. Across Europe, the rapid build-out of renewable generation outpaces the ability of grids to move electricity to where it’s needed. Curtailment, congestion, and long queues for grid connections already cost billions annually — and without decisive action, these costs will grow.
Pricing and Market Innovation: Surpluses of regional generation during sunny or windy days overwhelm local capacity, causing wholesale electricity prices to drop below zero and straining market economics. At the same time, smart-meter deployment and flexible pricing mechanisms are starting to incentivize industrial consumers to use power precisely when generation peaks, smoothing out demand.
So to finish here are three different perspectives on that debate within Europe (though you could certainly extend the argument to the United States as well).

Below are links to several recent articles on the issue - some focusing on the larger specter of wildfires in the area, but most simply looking at the potential impact of a bank using something as loan collateral (in this case cheese) and finding it might not be as durable as they hoped.

If you want/need a more formal take on the economic research behind this, a new paper released from the European Central Bank goes into a LOT more detail on the potential impact of extreme weather events on European economic activity. This is far beyond high school student level, but might interest some of you . . .

And finally (for this section), the story that originally caught my attention for this update was from our friends at Marketplace. Story and podcast episode are both linked below . . .
