Data Centers and Generation Capacity over the Next Decade: Potential Benefits of Flexibility
Flexible demand response offers the potential to significantly reduce the amount of new capacity needed to meet rapidly growing electricity demand from data centers over the next 5 to 10 years. Without flexibility, the additional electricity may largely be provided by new gas units; with flexibility, the capacity mix shifts more toward renewables.
Systems-Level Repurposing of Coal Assets: Insights from South Africa, India, and the United States
The global coal value chain is extensive and spans countries. Nearly 7,000 coal mines collectively produce over 8.5 billion tons of coal every year. More than 2,400 coal-fired power plants across the globe operate with a capacity of 2,175 GW. Then, there are numerous rail networks, trucks, and port terminals that constitute parts of the coal value chain. Yet in a net-zero world, this value chain will need to shrink rapidly, which could negatively impact the economies and communities that currently depend on it.
State-Level Heterogeneity in the Price Elasticity of Demand for Residential Electricity
Affordable, reliable electricity is essential for productive, healthy and thriving communities. Achieving this goal at least partly requires understanding the dynamic relationship between electricity prices and consumer demand is critical for utilities, regulators, and governments seeking to deliver affordable, reliable, and efficient energy. This paper presents updated estimates of a standard measure of price responsiveness in the US residential electricity market—price elasticity of demand for electricity (PEDE)—and explores how it varies across states.
Pathways to Keep Financing Flowing into Clean Electricity Sectors
In fall 2025, ACORE, Duke University’s Nicholas Institute for Energy, Environment & Sustainability, the EFI Foundation, and the World Resources Institute convened technology developers, finance providers, large-load customers, and legal and policy experts to explore how to keep finance flowing toward clean electricity sectors.
Participants defined three central challenges to keeping capital flowing into these projects:
Memorandum: Potential Removal of Interim Targets in the NC Carbon Plan
North Carolina Senate Bill 266 (SB266) removes interim carbon emissions targets from the NC Carbon Plan. This memorandum evaluates an analysis of removing these targets conducted by Joseph DeCarolis, Anderson de Queiroz, and Jeremiah Johnson at North Carolina State University (summary of analysis; full analysis), including how alternative assumptions might affect its overall conclusions.
The Energy Transition Accelerator as a Vehicle for Low-Carbon Development Capital: Opportunities, Challenges, and Uncertainties
Addressing the dual needs of development and decarbonization in low- and middle-income countries requires significant increases in public and private investment and project implementation. Announced in 2022 by the US Department of State, The Rockefeller Foundation, and the Bezos Earth Fund, the Energy Transition Accelerator (ETA) aims to drive such increases by leveraging carbon credits as a sector-wide channel for energy transition finance.
Planning for Growing Electricity Demand During an Era of Uncertain Renewables and Climate Policy
Electricity demand growth has accelerated significantly, a trend that is expected to continue for at least the next 5 to 10 years and is driven by new technologies such as data centers and the expansion of the manufacturing and industrial base in the United States. This analysis uses a variety of integrated resource plans from utilities and other groups to estimate how overall electricity demand may change over the next decade in several scenarios.
The People’s Republic of China’s Emissions Trading Scheme: Origins, Characteristics, and Lessons for Greater Asia
The People’s Republic of China is using the national emissions trading scheme (ETS) as a tool to bend the country’s emissions curve while cleaning its domestic environment, driving innovation, and capturing a greater share of high-value segments of the global economy. This background paper for the Asia-Pacific Climate Report 2024: Catalyzing Finance and Policy Solutions first explores the origins of the ETS and then looks at its characteristics and performance.
Energy Transitions at a Crossroads: Balancing Growth, Decarbonization, and Development
Can low- and middle-income countries meet human development imperatives while decommissioning fossil fuel infrastructure or avoiding further fossil fuel development? A high-level panel at Climate Week NYC 2024—moderated by Jackson Ewing and featuring executive in residence Alix Peterson Zwane alongside global investment leaders—attempted to address just that.
Projecting Electricity-Sector Investments Under the Inflation Reduction Act: New Cost Assumptions and Interactions with EPA’s Greenhouse Gas Proposal
Energy Pathways USA, an initiative of the Nicholas Institute for Energy, Environment & Sustainability at Duke University, has released a report that offers new insights into US energy transition investments. This report comprehensively models the intersecting effects of the Inflation Reduction Act, clean electricity development cost increases, and the impacts of proposed US Environmental Protection Agency greenhouse gas regulations for fossil fuels.
