Cold Chains, from Net to Fork: Evidence from Kenya on Livelihoods and Community Resilience

Small-scale fisheries in Kenya support more than 1.5 million livelihoods but face mounting climate and market shocks that threaten food security and income stability. Research led by Duke University and the University of Nairobi evaluated the Keep IT Cool model—a private enterprise linking fishing communities around Lake Victoria and Lake Turkana to higher value markets trough solar-powered cold storage and logistics.

Evaluating the Adaptation Benefits of Cold Storage and Market Connectivity for Kenyan Fisherfolk on Lake Turkana

Fishing plays a central role in the livelihoods and food security of many rural communities in Kenya, particularly around Lake Turkana, where climate variability, spoilage of catch, and limited market access have historically constrained economic opportunities. Keep IT Cool (KIC) is a social enterprise that provides solar refrigeration and cold chain logistics for smallholder chicken farmers and fisherfolk in Kenya.

A Pollution Crisis of Synthetic Plastic Polymers and their Hidden Chemical Complexity

The diverse material properties of plastic polymers have prompted their extensive use, resulting in widespread pollution, including environmental contamination by chemical additives used to enhance polymer properties. Additives have diverse biological impacts, underscoring a need to understand the hidden complexity of additive exposures from plastic polymer pollution.

Energy Solutions for Data Center: Comparative Analysis of Levelized Cost of Electricity (LCOE) and Recent Developments

The rapid growth of artificial intelligence (AI) and cloud computing has dramatically increased global data center energy consumption, challenging existing low-carbon infrastructure development. This study addresses a crucial gap by comparing the Levelized Cost of Electricity for wind, solar, solar plus battery storage, nuclear, and natural gas technologies tailored explicitly for meeting Meta’s data center energy demands through 2030. Our custom model incorporates detailed capital and operational costs, capacity factors, site-specific data, and sensitivity analyses of key variables.

Extreme Heat Risk Governance Framework and Toolkit

Extreme heat is one of the world’s most dangerous climate challenges, threatening health, livelihoods, and infrastructure. This new resource provides practical tools for national and local authorities to strengthen coordination, planning, and investment to protect people and systems from escalating heat impacts.

The Social Cost of Plastic to the United States

Plastic products are everywhere in daily life in the United States. Yet the economic, environmental and health costs of plastic to society reach up to $1.1 trillion per year—and that’s likely an underestimate.

How DOE’s Proposed Large Load Interconnection Process Could Unlock the Benefits of Load Flexibility

In the United States, the current system for interconnecting large electric loads, like data centers, to the grid has left all sides frustrated. Data center developers are mired in slow interconnection processes. Meanwhile, electricity customers face rising rates and threats to grid reliability as the nation’s grid operators struggle to interconnect new power plants and batteries to the system quickly enough to meet rising demand. This brief outlines policy considerations for FERC to evaluate and highlights processes and mechanisms that grid operators would need to develop in order to maximize the benefits of load flexibility for electricity consumers. FERC has docketed the DOE Advanced Notice Of Proposed Rulemaking (RM26-4) and requested an initial round of comments by November 14, 2025, and reply comments by November 28, 2025. UPDATE: FERC has extended the initial comment period to November 21, 2025, with reply comments due by December 5, 2025.

On the Back Burner: Experimental Evidence For Energy Transitions

A central challenge in the global transition to cleaner energy is how governments can design policies that deliver large social benefits while facing trade-offs in energy security, fiscal costs, and household adoption frictions. The authors studied this question in urban Nepal, where cooking is dominated by imported liquid petroleum gas (LPG), but abundant hydropower makes both large-scale electrification and improved energy security feasible.

Powering Livelihoods by Avoiding Household Damages: Household Willingness to Pay For Electricity Reliability in Sierra Leone

The authors estimate the marginal willingness to pay (WTP) for improved electricity service reliability in a nationally representative sample 1,047 grid or mini-grid connected households in Sierra Leone, using two complementary valuation approaches. Analyzing data from a discrete choice experiment, they find that, on average, households exhibit strong preferences for shorter outages; fewer daytime and evening outages, compared to nighttime outages; and prior notification, though there is heterogeneity in the relative weights ascribed to each of these attributes.

An Implementation Science Analysis of an Ethanol Cooking Fuel Promotion Project in Dar es Salaam, Tanzania

In this study, the authors conduct an implementation science analysis of Phase I of the “Promotion of Bio-Ethanol as Alternative Clean Fuel for Cooking in the United Republic of Tanzania” project, describing the roll-out of this market-based bioethanol stove program. Leveraging program administrative data, individual interviews, and focus group discussions, we apply the RE-AIM framework to evaluate the successes and limitations of the project.
