Boise’s $1 Million Geothermal Breakthrough: A Bold Step Toward Affordable Clean Heating
By: Robert Buluma
In the global race to build cleaner, more affordable cities, innovation often emerges from unexpected places. One such place is Boise, Idaho, a community already known for its pioneering use of geothermal heating. In early 2026, Boise captured international attention after winning a $1 million grant through the Bloomberg Philanthropies Mayors Challenge, a global competition that rewards cities developing groundbreaking solutions to pressing urban problems.
The recognition was not simply about technological innovation. Boise’s winning proposal demonstrated how geothermal energy can be used to reduce the cost of living, specifically by lowering utility bills for residents in affordable housing developments.
With the award, Boise now plans to build a new apartment complex powered by geothermal heating—potentially reducing energy costs for residents by up to 80 percent. The initiative highlights how cities can leverage local natural resources to address social challenges like housing affordability and energy sustainability.
The project has positioned Boise as a global example of how geothermal energy can transform urban infrastructure while improving everyday life for citizens.
The Bloomberg Mayors Challenge: Innovation on a Global Stage
The winning idea emerged from the Bloomberg Philanthropies Mayors Challenge, an international competition designed to encourage cities to develop creative solutions for complex urban issues.
Founded by former New York City Mayor Michael Bloomberg, the initiative invites municipalities worldwide to submit proposals addressing challenges such as:
- Affordable housing
- Environmental sustainability
- Waste management
- Emergency services
- Urban infrastructure
The 2025 competition drew 630 cities from around the world, each presenting innovative proposals aimed at solving real community problems.
Boise’s geothermal-powered affordable housing concept stood out among the submissions. The city advanced to the final stage as one of the top 24 global winners, securing the $1 million grant and gaining international recognition.
Other cities recognized in the competition included global urban centers such as Barcelona, Budapest, Cape Town, and Fez.
Among American cities, Boise shared the $1 million prize category with Lafayette, Louisiana, and South Bend, Indiana.
The recognition demonstrated that innovative climate solutions can emerge not only from major global capitals but also from mid-sized cities willing to think creatively.
The Vision: Affordable Housing Powered by Geothermal Energy
At the heart of Boise’s proposal is a simple but powerful idea: use geothermal heat to reduce energy costs for affordable housing residents.
The city plans to develop an apartment complex containing up to 300 units near Boise State University in an area known as the Lusk District.
The new development will rely on Boise’s direct-use geothermal heating system, which draws naturally heated water from underground reservoirs and distributes it through pipelines to heat buildings.
According to Boise Mayor Lauren McLean, the project represents a new milestone in geothermal energy deployment.
She explained that this initiative will likely become the first project of its kind where direct geothermal heat is used specifically for multifamily affordable housing.
The potential impact on residents could be dramatic. Because geothermal systems eliminate the need for expensive fossil fuels, utility bills for tenants are expected to drop significantly.
Estimates suggest that households could see energy costs reduced by up to 80 percent, offering substantial financial relief for families struggling with rising living expenses.
Boise’s Unique Geothermal Heritage
While geothermal energy is gaining global attention today, Boise has been a pioneer in the field for more than a century.
The city’s geothermal story began in the late 19th century, when local leaders realized the potential of naturally occurring hot springs in the region.
One of the earliest geothermal heating systems was established by the Boise Warm Springs Water District, which constructed a network of pipelines that carried hot water from underground springs into homes.
This system became one of the oldest district geothermal heating systems in the United States.
Today, Boise continues to operate an extensive geothermal network that heats numerous buildings across the city.
These include:
- City government buildings
- The Idaho State Capitol
- Facilities at Boise State University
- More than 90 commercial and public buildings downtown
This long history of geothermal energy use gave Boise a unique advantage in designing the affordable housing project.
How Geothermal Heating Works
Unlike solar or wind power, geothermal energy taps into heat stored naturally within the Earth’s crust.
In Boise’s system, underground aquifers contain hot water heated by geothermal activity deep beneath the surface. Wells bring this water to the surface, where it flows through heat exchangers and pipelines that warm buildings.
Once the heat has been transferred, the cooled water is typically returned underground through reinjection wells.
The process has several advantages:
- Continuous energy supply regardless of weather
- Minimal carbon emissions
- Stable energy prices
- Long system lifetimes
Because geothermal heat comes directly from the Earth, it provides a reliable source of baseload thermal energy.
Public-Private Collaboration
To deliver the geothermal-powered housing project, Boise has formed a partnership with the private sector.
The apartment complex will be constructed by J. Fisher Companies, a developer selected through a competitive bidding process.
The project represents a public-private partnership, combining municipal infrastructure planning with private-sector construction expertise.
The housing development will be located in Boise’s Lusk District, a rapidly growing urban neighborhood that has seen significant residential development in recent years.
Its proximity to Boise’s geothermal pipeline network makes it an ideal location for connecting new buildings to the system.
Extending the Geothermal Network
While Boise already operates a geothermal heating system, connecting the new housing project will require expanding the city’s geothermal infrastructure.
Part of the $1 million grant from Bloomberg Philanthropies will fund the extension of geothermal pipelines needed to reach the new apartment complex.
City officials hope to complete this infrastructure expansion by 2028, allowing the housing development to begin using geothermal heat shortly after construction.
The project will also receive continued support from Bloomberg Philanthropies in the form of:
- Technical assistance
- Strategic guidance
- Funding for specialized project staff
Two dedicated employees funded through the grant will join Boise’s municipal team to help oversee implementation.
A Model for Sustainable Cities
For Boise’s energy program manager Katie O’Neil, the project represents an opportunity to demonstrate geothermal energy’s broader potential.
She believes Boise’s geothermal system could fundamentally reshape how the city approaches energy.
According to O’Neil, Boise is currently the only city in the United States with a geothermal district heating system of this scale, placing it among a small group of cities globally that rely heavily on underground heat.
By applying this system to affordable housing, Boise hopes to demonstrate a model that other cities can replicate.
Why Geothermal Matters for Housing Affordability
Energy costs are one of the largest ongoing expenses for many households. For families living in affordable housing, utility bills can consume a significant portion of monthly income.
Geothermal heating can help solve this problem by dramatically reducing the cost of heating buildings.
Unlike gas or oil heating systems, geothermal infrastructure:
- Requires no fuel purchases
- Has low operating costs
- Delivers consistent energy prices
These advantages make geothermal particularly attractive for housing developments intended to remain affordable for decades.
In the Boise project, the geothermal system could help ensure that housing remains economically accessible long after construction is completed.
Global Recognition for Boise
The Bloomberg award brought Boise international recognition, placing the city on the map as a leader in innovative urban energy solutions.
Officials involved in the project believe the recognition validates the city’s long-term climate and sustainability strategy.
Mayor Lauren McLean emphasized that the project represents more than a one-time innovation.
Instead, she sees it as the beginning of a larger effort to expand sustainable energy infrastructure across the city.
If successful, geothermal heating could eventually power additional housing developments, public buildings, and commercial facilities throughout Boise.
Lessons for the Global Geothermal Sector
Boise’s project offers several insights for cities and energy planners around the world.
Existing Resources Can Be Game-Changers
