Biography

Dr. Sonia Yeh is a research scientist at the Institute of Transportation Studies, University of California, Davis. She is a faculty member of the Graduate Group in Transportation Technology and Policy (TTP) and an adjunct professor at the Department of Engineering and Public Policy, Carnegie Mellon University. Her primary research interest is to advance the understanding of future energy systems and their environmental and social impacts, and to seek solutions that improve the societal process of making decisions toward a low-carbon energy system. Her expertise is in energy market economics and modeling, lifecycle analysis of greenhouse gas emissions, alternative transportation energy use and modeling, sustainability standards for biofuels, and technological change induced by government policy. She co-leads the UC research teams with UC Davis and UC Berkeley in supporting the implementation of California's Low Carbon Fuel Standard since 2007 and is the co-director of the National Low Carbon Fuel Standard Project. She serves on many governmental advisory panels and chaired expert workgroups for governments and NGOs.

TTP 289A-002 Energy Modeling for Policy Analysis

The course will familiarize students with building energy models for policy analysis. We will explore several facets of energy systems modeling including supply and demand, energy technologies, emissions, technological change and diffusion, scenario analysis, and uncertainty. We will also introduce techniques for policy analysis. The students will learn to integrate multi-disciplinary knowledge, build analytical tools, conduct alternative scenario analysis, and carry out sensitivity and uncertainty analysis. The student will be introduced to several genres of energy models and will be required to complete a number of model building exercises using Excel, other tools introduced in class, or developed by students based on his/her own skills (advanced knowledge of computer programming is not a requisite for this class). Students will become familiar with forecasting energy use and demands, gain experience of building techno!economic models, and develop skills for policy analysis. Assignments will draw on real-life policy problems at the state, federal, and international level.

Oregon Democrats have placed a controversial and newly amended low-carbon fuel standard bill early on the 2015 legislative schedule despite Republican threats to block other important bills down the line if it passes. Researchers from the University of California-Davis told lawmakers the impact was around a third of a cent per gallon in 2014. “The exact purpose of (the) policy is to move away from the status quo and reduce emissions through more use of low-carbon fuels via market competition and technology innovation,” said Sonia Yeh, a senior researcher with the UC-Davis Institute of Transportation Studies who was involved in implementing the California program.

ITS-Davis researchers Sahoko Yui and Sonia Yeh warn that "if policies are not strictly enforced there is the potential to hugely increase greenhouse gas emissions from palm production," in their study of Brazil's deforestation policy for palm oil production.

November 14, 2013

Sonia Yeh, from the UC Davis Institute of Transportation Studies, explains that "expanding millions of hectares of Brazilian land to produce palm oil for food or for renewable, clean-burning biodiesel could result in extremely high emissions of carbon dioxide unless strict controls are put in place."

Companies "are meeting and exceeding the standard," said Sonia Yeh, the report's lead author and a research scientist at the Institute of Transportation Studies at the University of California, Davis. But the standard remains in legal limbo.
