Guangzhi is a PhD student in Energy Systems Analysis at Tsinghua University. He has bachelor’s degrees in Electrical Engineering and in Management from Tsinghua University. He has been a visiting student at the University of Bath and at the Israel Institute of Technology.
His work is focused on the role of carbon pricing and renewable energy deployment in China.
Guangzhi will be a visiting student at RAEL from October 2019– July 2020.
As an undergraduate Kelly was invited to work as a GSR to compile data on decentralized renewable energy (DRE) in partnership with Power for All (P4All) as part of a larger effort to research and to build the case for universal electricity access by 2025 through distributed renewable energy. In this project Kelly is working with Dr. Rebekah Shirley and Professor Dan Kammen of UC Berkeley Energy and Resources Group.
In the Spring of 2018 Kelly is also a Visiting Student and mini-grid research student at the State Key Laboratory of Transmission Equipment and System Security and New Technology at Chongqing University where she is supervised by Professor Minyou Chen of the School of Electrical Engineering.

We explore the operations, balancing requirements, and costs of the Western Electricity Coordinating Council power system under a stringent greenhouse gas emission reduction target. We include sensitivities for technology costs and availability, fuel prices and emissions, and demand profile. Meeting an emissions target of 85% below 1990 levels is feasible across a range of assumptions, but the cost of achieving the goal and the technology mix are uncertain. Deployment of solar photovoltaics is the main driver of storage deployment: the diurnal periodicity of solar energy availability results in opportunities for daily arbitrage that storage technologies with several hours of duration are well suited to provide. Wind output exhibits seasonal variations and requires storage with a large energy subcomponent to avoid curtailment. The combination of low-cost solar technology and advanced battery technology can provide substantial savings through 2050, greatly mitigating the cost of climate change mitigation. Policy goals for storage deployment should be based on the function storage will play on the grid and therefore incorporate both the power rating and duration of the storage system. These goals should be set as part of overall portfolio development, as system flexibility needs will vary with the grid mix.
Noah Kittner is now a Professor in both City and Regional Planning, and Global Public Health at the University of North Carolina, Chapel Hill.
Noah Kittner was a PhD student in the Energy and Resources Group at UC Berkeley and researcher in the Renewable and Appropriate Energy Laboratory. After graduating with a BS in Environmental Science from UNC-Chapel Hill (highest honors), Noah was a Fulbright Fellow at the Joint Graduate School for Energy and Environment in Bangkok, Thailand researching technical and policy aspects of solar electricity and sustainability assessment. Recently, he co-authored a Thai Solar PV Roadmap with colleagues at Chulalongkorn University.
He has worked on renewable energy issues in a variety of contexts, including measuring land use change and biomass fuel uses in western Uganda, installing solar panels in Mexico, and electricity grid modeling in Kosovo. He is supported through the Berkeley Center for Green Chemistry as a SAGE-IGERT fellow, National Science Foundation as a Graduate Research Fellow, USAID, and has won an award from the National Go Solar Foundation for his work on solar photovoltaics.
