Research

Wei Peng’s research centers on developing computational and integrated assessment models that illuminate the complex trade-offs embedded in climate and energy policy. Her work bridges energy systems, air quality, public health, and political economy to understand how policy decisions ripple across social, environmental, and institutional dimensions. She has published extensively in top journals such as Nature, Nature Climate Change, Nature Sustainability, and PNAS, highlighting her contributions to modeling climate strategies that are both technically sound and socially grounded. Her scholarship emphasizes the importance of incorporating real-world political and institutional constraints into energy system models to design policies that are feasible, durable, and equitable.

Figure 6 from the 2025 paper, “The Effects of Renewable Energy Scaling on Sub-annual Air Pollution Emission Dynamics from the Power Sector: a Western U.S. Case Study”, shows impacts of renewable scaling on the distribution of daily health damages associated with the air pollutant emissions from power plants.

A major thread of Peng’s research focuses on human-centered decarbonization: how energy transitions affect communities, public health, and societal equity.

Peng is part of the Andlinger Center for Energy and the Environment faculty because her research directly advances the Center’s mission: developing solutions that support sustainable energy systems while addressing environmental and societal impacts. Her expertise in integrated modeling, climate equity, and political economy is uniquely aligned with the Center’s interdisciplinary approach, which bridges engineering, policy, and environmental science. By producing decision-relevant insights that integrate technology, governance, and human well‑being, Peng contributes the type of cross-sector, systems-level thinking essential for guiding real-world energy transitions.
