The Future of Urban Housing Is Energy-Efficient Refrigerators

Via MIT Technology Review, a look at how adapting old, energy-inefficient buildings is less sexy but far greener than many high-tech solutions: The scars and pockmarks of the aging apartments and housing units under the purview of the New York City Housing Authority don’t immediately communicate the idea of innovation. The largest landlord in the […]

To Solve Climate Change, We Need To Restore Our Sponge Planet

An interesting comment in Nature Water on how to help stabilize the climate by moving towards a Sponge Planet. Humans have degraded 75 percent of Earth’s land, destabilizing the water cycle, amplifying effects of excess CO2. The water cycle is a key climate stabilizer but overlooked by policymakers. Restoring wetlands, floodplains, forests, recreating a Sponge […]

Thermal Energy Networks: The Next Big Thing

Via Volts, commentary on the potential of thermal energy networks: In this episode, I revisit thermal energy networks with HEET’s Zeyneb Magavi and Eversource’s Eric Bosworth. What was once a novel concept — replacing gas networks with shared ground-source heat pumps — is now being piloted across the country. We explore the technology’s remarkable efficiency […]

ABOUT
BLACK SWANS GREEN SHOOTS
Black Swans / Green Shoots examines the collision between urbanization and resource scarcity in a world affected by climate change, identifying opportunities to build sustainable cities and resilient infrastructure through the use of revolutionary capital, increased awareness, innovative technologies, and smart design to make a difference in the face of global and local climate perils.

'Black Swans' are highly improbable events that come as a surprise, have major disruptive effects, and that are often rationalized after the fact as if they had been predictable to begin with. In our rapidly warming world, such events are occurring ever more frequently and include wildfires, floods, extreme heat, and drought.

'Green Shoots' is a term used to describe signs of economic recovery or positive data during a downturn. It references a period of growth and recovery, when plants start to show signs of health and life, and, therefore, has been employed as a metaphor for a recovering economy.

It is my hope that Black Swans / Green Shoots will help readers understand both climate-activated risk and opportunity so that you may invest in, advise, or lead organizations in the context of increasing pressures of global urbanization, resource scarcity, and perils relating to climate change. I believe that the tools of business and finance can help individuals, businesses, and global society make informed choices about who and what to protect, and I hope that this blog provides some insight into the policy and private sector tools used to assess investments in resilient reinforcement, response, or recovery.
