Streetlights Are Good, Can Be Really Good.
Thanks to some work out of Penn State
The streetlight. A staple of urban and suburban life. Keeping things safer, enabling late-night strolls and journeys.
The electric car. Quieter, more efficient, safer, better for the environment.
Thanks to Penn State, these two aspects of modern life come together in an interesting and good way.
Electric vehicles promise a cleaner, quieter future, but that promise crashes into a frustrating reality: for millions of urban residents, charging a car is a logistical luxury. For apartment dwellers, condo residents, or anyone without a private garage, home charging is simply not an option. This accessibility gap is more than an inconvenience; it represents a fundamental equity barrier that threatens to make dense neighborhoods obsolete in the transition to clean transportation.
But what if the solution to this complex, city-wide problem wasn’t a complex new infrastructure, but something already standing on every street corner?
A new report by Penn State researchers offers an elegant, data-driven answer: turning streetlights into charging stations. The argument for the streetlight is simple, yet powerful. The pole is there. Already installed, already energized, and already municipally owned. By repurposing this infrastructure, cities can deploy curbside charging that is practical and fair, circumventing the massive cost and time involved in new trenching, construction, and complex land negotiations. As one researcher noted:
“Working with streetlights is pretty straightforward.”
To prove this shift was possible, Penn State partnered with allies in Kansas City, Missouri, to test 23 street lighting charging stations. The program was deployed with deliberate structure and purpose, marrying data modeling with a focus on the intricacies of the modern American city.
The siting model was two-tiered. The first tier used AI, analyzing years of analyzing data on traffic patterns, parking availability, and nearby destinations to predict where charging demand would be highest. The second tier introduced an urban design layer. This ensured the new chargers were not just placed where they would be busiest, but to offer access to underserved neighborhoods, ensuring the potential benefits were spread across diverse areas.
The results of the year-long pilot surpassed expectations. The retrofitted streetlight chargers were found to be better than traditional stations across several key metrics:
Cost to install: Because the infrastructure exists.
Recharge Speeds: Coming in faster than commercial stations.
Accessibility: Street lights are on streets, where cars are parked/driven.
What also stands out is that this type of charger deployment is it represents a novel framework for urban design/urban optimization. By leveraging the streetlight’s connection to dedicated civic electricity lines, power isn’t being drawn to new locations; it’s simply being redistributed at existing terminals. There’s minimal infrastructure compromise—just distributed benefit.
This represents an often-overlooked dimension of innovation. Transformation doesn’t require creative destruction or wholesale replacement. Breakthroughs can be equally consequential when they emerge from recognizing latent potential in existing systems. The ubiquitous streetlight—otherwise unremarkable—becomes, through conceptual reframing, a distributed energy network. No excavation, no massive new building, no eminent domain, just poles and electricity. Two things we have in good amounts.
That’s today’s good thing: problem-solving through reframing rather than replacement. Sometimes progress requires not building something new, but seeing what’s already there with fresh eyes.
