A New Perspective on an Old Fixture
Streetlighting is one of the most visible—and overlooked—components of city infrastructure. Found on every arterial, collector, and neighborhood street, these fixtures quietly consume millions of kilowatt-hours every year, often powered by fossil-fueled grids.
But as cities pursue decarbonization and resilience goals, they’re beginning to ask a new question: Can Streetlights Actually Help Reduce a City’s Carbon Footprint?
The answer is yes—if they’re reimagined as part of the solution. Off-grid solar streetlighting technology has evolved beyond early pilots. Today, infrastructure-grade systems like Fonroche’s SmartLight with Power 365® offer grid-free, carbon-free lighting that’s already transforming streets across the country.
In this article, we explore how cities—from Keene, NH to Los Angeles—are using solar streetlighting to cut emissions, strengthen resilience, and modernize public safety.

Why Streetlighting Matters in the Carbon Equation
Streetlighting is often treated as a static cost—an accepted part of utility infrastructure. But in many cities, it’s also one of the largest single contributors to municipal energy use, consuming up to 40% of public electricity budgets.
That energy use comes with a price:
- Higher emissions, particularly in regions where the grid still relies on coal or natural gas
- Hidden carbon costs from installation, trenching, copper wiring, and long-term maintenance
- Vulnerability to grid disruptions, which can require carbon-intensive repair operations
A typical 80-watt streetlight operating 4,200 hours per year consumes over 330 kWh annually. Multiply this across thousands of fixtures, and the emissions add up fast.
The Opportunity in Plain Sight
Every conventional streetlight converted to a zero-emission, off-grid solar system reduces both operational and embedded carbon. And unlike many carbon-reduction strategies, streetlighting upgrades don’t require major behavior change, public outreach, or policy reform.
They just require better infrastructure.
Real-World Results: How Cities Are Cutting Carbon with Solar Streetlights
Across the U.S., cities and agencies are already proving that streetlight upgrades can be climate action. These deployments show how off-grid lighting isn’t just feasible—it’s effective, scalable, and delivering measurable environmental benefits.
Keene, New Hampshire: Solar in All Four Seasons
In pursuit of its climate and resilience goals, Keene is piloting solar streetlighting across key public spaces. The city is testing whether solar can fully replace grid-tied lighting—even in the snow-heavy, low-irradiance conditions of the Northeast.
What it shows: With proper sizing and energy management, solar lighting can support year-round operation in four-season climates—reducing emissions without compromising performance.
Vallejo, California: Rapid Recovery, Zero Emissions
When a transformer failure left a corridor in Vallejo dark for two years, utility repairs stalled. Rather than wait, the city deployed 30 Fonroche SmartLights to restore lighting in weeks—completely off-grid and emissions-free.
What it shows: Solar lighting can bypass utility delays, restore public safety, and eliminate grid emissions—even in urgent recovery scenarios.
Los Angeles, California: Fighting Wire Theft and Emissions
The LA Bureau of Street Lighting approved Fonroche solar systems for citywide deployment after years of success in theft-prone areas. With no copper wire and no trenching, these lights address both infrastructure security and sustainability goals.
What it shows: Cities can cut carbon and cut crime—deploying solar lights that stay online through outages and require no underground utilities.
Kentucky Transportation Cabinet (KYTC): Decentralized, Decarbonized
KYTC is rolling out solar lighting across multiple districts, replacing aging grid systems. Internal DOT crews have been trained to install solar units in under 45 minutes per light, with no trenching, no grid access, and no long-term maintenance.
What it shows: Even in rural or state-level deployments, solar lighting can scale efficiently—lowering both emissions and operational costs.
Three Ways Solar Streetlighting Cuts Carbon
For cities and agencies looking to make measurable progress on climate goals, solar streetlighting delivers impact in three keyways:
1. Zero Operational Emissions
Once installed, Fonroche solar lights operate completely off-grid, drawing power only from the sun. Each system uses Power 365®, Fonroche’s proprietary energy management platform, to optimize energy use across seasons and weather patterns. The result?
- 365 nights of reliable lighting per year
- No kilowatt-hours from the grid
- No carbon emissions from utility power
This eliminates Scope 2 emissions from municipal lighting—permanently.
2. No Carbon-Intensive Construction
Grid-tied lighting requires trenching, conduit, concrete, copper wire, and transformer coordination—each with its own environmental footprint. Solar lighting avoids all of it.
Fonroche systems are installed like street trees: no grid permits, no digging up roads, no diesel generators on-site. The construction-related emissions drop significantly, especially in:
- Wetlands or protected lands
- Brownfield or redevelopment sites
- Neighborhoods sensitive to disruption
No trench = fewer emissions, less disruption, and lower embodied carbon.
3. Avoided Emissions from Grid Failures and Maintenance
Outages, copper theft, and storm damage to grid infrastructure trigger a hidden carbon cost: repair crews, truck rolls, generators, and replacement parts. Solar lighting avoids that entire cycle.
Fonroche lights remain operational:
- During blackouts and grid failures
- When copper theft disables nearby systems
- In post-disaster zones where infrastructure is compromised
Fewer emissions from utility trucks, fewer emergency dispatches, and a safer, more self-sufficient streetscape.
Beyond Carbon: Resilience, Cost, and Equity
Cutting emissions is critical—but it’s just one piece of the infrastructure puzzle. Cities and agencies also need solutions that are resilient in crises, cost-stable over time, and equitable in reach. Solar streetlighting checks all three boxes.
Resilience: Lights Stay On When the Grid Goes Down
With climate-related blackouts and overloaded grids becoming more common, grid-independent lighting is no longer a luxury—it’s a necessity.
Fonroche’s off-grid systems:
- Continue operating during wildfires, hurricanes, or outages
- Require no backup generators or emergency power plans
- Use smart diagnostics to monitor system health and performance
When the power goes out, Fonroche lights stay on—protecting visibility, safety, and access.
Cost Efficiency: Low Ongoing Costs, High ROI
Solar streetlights eliminate utility bills and reduce long-term O&M. With no trenching, no copper, and virtually no scheduled maintenance for 10+ years, cities see:
- Installation cost savings up to 75%
- Zero electricity costs
- Reduced maintenance dispatches and labor demands
Stable, predictable lighting budgets—especially important for grant-based and lean municipal operations.
Equity: Lighting Without Infrastructure Barriers
Grid-tied systems often bypass areas that are remote, underfunded, or logistically difficult to serve. Fonroche solar lighting removes those barriers.
It can be installed:
- On tribal lands, brownfields, or underserved corridors
- In parklands, wetlands, and historic districts without damaging the site
- To support Vision Zero, Safe Routes to School, and walkability plans that prioritize vulnerable users
Infrastructure equity isn’t just about access—it’s about deliverability. Solar makes lighting possible where grid projects stall or fail.
From Pilot to Policy: Making Solar the New Standard
What once started as small-scale pilots is now reshaping infrastructure policy across the U.S. and beyond. Solar streetlighting has matured—technically, economically, and politically—into a mainstream solution for cities serious about climate action, resilience, and modernization.
