Solar Power World
By SPW | May 5, 2026
 
I spent a week in Barcelona this April, and I left the Catalonian capital with the understanding that cities can be living things. They cannot breathe or think; they have no arteries carrying oxygen-rich blood or mouths with which to speak or eat. Yet, even without a brain, a city can bear a long memory of itself and evolve while embracing its lineage.
It’s difficult to describe what characteristics support this claim. At any hour, on any day in Barcelona, there seems to be a reason for people to gather in the most unexpected places. Many of the people who live there are open about what they support, draping flags from their balconies, hanging fliers in store windows or painting the words of causes onto walls and train cars.
While walking streets older than our country, I saw solar panels peeking over the parapet walls of ornate buildings. Enclosed bus stops throughout the city had brightly illustrated posters of construction workers installing solar panels – and these were issued by the Barcelonian government. The shelves of bookshops carried titles from Spanish publishers focused on environmental and climate issues.
I lived this week as a tourist — sampling the conveniences of a place afforded to those who don’t live there. For that reason, I acknowledge that my version of Barcelona is a skewed version of Barcelona. But in my nearly 33 years on this planet, places I’ve visited and lived have quickly homogenized to the point that you can find the same few things on any block in any major city in the United States.
Barcelona is also grappling with the same kind of commercialization and rising cost of living — as is everywhere else in the world. The difference is Barcelona is clinging tightly to its identity — a culture with centuries-old roots — while still embracing modern technologies like renewables.
The Barcelonian government itself has spearheaded deploying solar PV on municipal infrastructure. In 2027 alone, the city reportedly plans to install 381 solar projects on municipal buildings.
This maintenance of character feels rare in a contemporary context.
I understand — a city isn’t a county, isn’t a state, isn’t a country. Detractors can choose to handwave forward progress on critical infrastructure like a modernized grid powered by renewable energy, because it hasn’t been done yet. But a precedent isn’t a precedent unless someone sets it. We’re reeling from the whiplash of oil costs from yet another war, when there are still millions of roofs with space for solar.
We’ve already built so much renewable infrastructure here in the United States. There’s still much more that needs to be built to reduce our reliance on finite fuel sources. This issue of Solar Power World is focused on topics of maintenance and how we can ensure our progress isn’t lost in the process.
