The Science and Side Effects of Geoengineering

The purpose of this forum discussion is to explore the science behind different ideas to deliberately manipulate the Earth’s climate to offset the warming due to the anthropogenic addition of greenhouse gases. The basis for this discussion will be the recent National Research Council reports “Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration” and “Reflecting Sunlight to Cool Earth”. We will begin with the history of intentional climate manipulation and lessons that have been learned from attempts at weather modification

A partial list of our past speakers follows along with their presentation abstracts.

DR. LAURENCE DELINA (FALL 2018)

Dr. Laurence Delina conducts research at the Frederick S. Pardee Center for the Study of the Longer-Range Future at Boston University. He is an Earth System Governance Research Fellow and an Associate at the Center for Governance and Sustainability at the University of Massachusetts Boston. Dr. Delina’s research explores the governance and institutional arrangements in the politics and policy of sustainability, focusing on accelerated sustainable energy transitions and the climate action movement in the context of rapid mitigation to anthropogenic climate change.

Presentation Abstract: Accelerating sustainable energy transitions in developing countries: energy democracy in a non-democracy

Accelerating sustainable energy transition to address the rapid impacts of anthropogenic climate change is now an imperative; but can these processes be accomplished democratically even in non-democratic places? In this talk, I will show how energy transition and democracy can be mutually inclusive—and go further to explore the promise of scaling up democratically produced energy transitions. This talk will focus on a case study of deliberatively produced energy transition as a communal practice for expanding energy transitions in rural Thailand. Using field/site observations, complemented by face-to-face interviews and group discussions, the talk will proceed in two stages. I will first empirically describe how such rural energy transition practice performed well against the ideals of deliberation: inclusive, authentic, and influential—thus underlining the compatibility between a robust democratic exercise and green outcomes. Second, I will normatively propose how such small-scale transitions can be scaled up in a deliberative system for its scaling potential—and what could be the tensions and challenges.

Dr. JING LI (SPRING 2018)

Dr. Jing Li is currently a Postdoctoral Associate of the MIT Energy Initiative. In Fall 2018, she will join the MIT Sloan School of Management as Assistant Professor of Applied Economics. Her research interests include Industrial Organization, Environmental and Energy Economics. She holds a Ph.D. in economics from Harvard and BS in Mathematics and economics from MIT. 

Presentation Abstract:  Compatibility and Investment in the U.S. Electric Vehicle Market

Competing standards often proliferate in the early years of product markets, potentially leading to socially inefficient investment.  This paper studies the effect of compatibility in the U.S. electric vehicle market, which has grown ten-fold in its first five years but has three incompatible standards for charging stations.I  develop  and  estimate  a  structural  model  of  consumer  vehicle  choice  and  car manufacturer  investment  that  demonstrates  the  ambiguous  impact  of  mandating compatibility standards on market outcomes and welfare.  Compatibility may benefit consumers by providing access to all existing charging stations. However, firms  may  cut  back  on  their  investments  because  the  benefits  from  one  firm’s investments  spill  over  to  rivals.   Firm  response  in  investment  may  erode  consumer gains from compatibility.  I estimate my model using U.S. data from 2011to  2015  on  vehicle  registrations  and  charging  station  investment  and  identify demand  elasticities  with  variation  in  federal  and  state  subsidy  policies.  Counterfactual simulations show that mandating compatibility in charging standards would decrease duplicative investment in charging stations by car manufacturers and increase the size of the electric vehicle market.

Presentation Abstract:  Bringing Equity and Inclusivity in the Objective Function: New Methods for Planning and Management of Energy and Water Systems

Traditional methods for infrastructure planning and design optimization of systems providing important services (such as energy and water supply) focus on least-cost and maximum technical performance objectives. Furthermore, such systems are often analyzed for impacts and benefits at large scales such as at national or state level. The primary focus on cost and technical efficiency leads to solutions that optimize on these objectives, while other important issues such as of equity and inclusivity (that are important for systems providing vital societal services) are left unaddressed. Such technical solutions provide aggregate benefits but often mask important distributional aspects and can add to widening disparities such as in access to energy and clean water. In this seminar, concepts of inclusive development are used to formulate quantitative metrics and employed for system planning, design optimization, and management strategy. The approach is illustrated through a set of case studies on micro-hydro power portfolios, waste-to-energy systems, and canal irrigation systems.

 

Professor William clark (Spring 2018)

William Clark is the Harvey Brooks Professor of International Science, Public Policy and Human Development at the Harvard Kennedy School.  Trained as an ecologist, his research focuses on sustainability science: understanding the interactions of human and environmental systems with a view toward advancing the goals of sustainable development. He is particularly interested in how institutional arrangements affect the linkage between knowledge and action in the sustainability arena.

Presentation Abstract:  Crafting Usable Knowledge for Sustainable Development (presentation)

This talk will distill core lessons about how researchers (scientists, engineers, planners, etc.) interested in promoting sustainable development can increase the likelihood of producing usable knowledge. I will draw the lessons from both practical experience in diverse contexts around the world and from scholarly advances in understanding the relationships between science and society. Many of these lessons will be familiar to those with experience in crafting knowledge to support action for sustainable development. However, few are included in the formal training of researchers. As a result, when scientists and engineers first venture out of the laboratory or library with the goal of linking their knowledge with action, the outcome has often been ineffectiveness and disillusionment. I will therefore articulate a core set of lessons that I believe should become part of the basic training for researchers interested in crafting usable knowledge for sustainable development. These lessons entail at least four things researchers should know, and four things they should do. The knowing lessons involve understanding the coproduction relationships through which knowledge making and decision making shape one another in social–environmental systems. I will highlight the lessons that emerge from examining those coproduction relationships through the ICAP lens, viewing them from the perspectives of Innovation systems, Complex systems, Adaptive systems, and Political systems. The doing lessons involve improving the capacity of the research community to put its understanding of coproduction into practice. I will highlight steps through which researchers can help build capacities for stakeholder collaboration, social learning, knowledge governance, and researcher training.

 

Professor Rohini Pande (Spring 2018)

Rohini Pande is an economist at Harvard Kennedy School whose research examines the economic costs and benefits of informal and formal institutions in the developing world and the role of public policy in affecting change. Pande is Professor, co-director of the Evidence for Policy Design Initiative, and Area Chair for International Development at the Harvard Kennedy School, co-chair of the Political Economy and Government Group at J-PAL and Research Associate at the National Bureau of Economic Research (NBER). 
Pande received a BA in Economics from Delhi University, a Master's from Oxford University and a PhD in Economics from London School of Economics. 

Presentation Abstract:  Lining the `Right Pockets': Using economic insights to address the political challenges of development policy

The share of the global population living in extreme poverty has dropped 34 percentage points since 1981. Such reductions are unlikely to automatically continue, given the shifting distribution of a majority of the poor into middle-income countries, the sharp rise in inequality within these countries, and the changing nature of growth. The talk will discuss the case for investments in the "invisible infrastructure" that allows the poor to exit poverty, and argue that an effective domestic state remains central to its provision. Using the case study of India’s federal workfare program the talk will discuss research learnings on how to improve implementation of components of the invisible infrastructure and the importance of giving the poor the power to demand the reforms they need by solving agency problems between citizens, politicians, and bureaucrats.

 

Professor Corwin zigler (fall 2017)

Dr. Corwin Zigler is an assistant professor of biostatistics at the Harvard TH Chan School of Public Health.  He specializes in the development and application of Bayesian methods for causal inference in complex observational studies, with particular focus on policy evaluation and comparative effectiveness research.  He directs one project of the EPA-funded Harvard/MIT Air Climate and Energy Center focused on evaluating health impacts of regulations targeting US power plants.

Presentation Abstract:  Combining Statistical Methods with Atmospheric Models for “Direct” Accountability Assessment

Evaluating the health impacts of specific air quality interventions (sometimes referred to as “accountability assessment”) is fundamentally challenged by long-range pollution transport since interventions taken at specific locations can impact population health at great distances. To accommodate transport, many health impact investigations combine outputs from chemical transport models with “health effect” estimates from other (e.g., epidemiological) studies to indirectly infer the health impacts of interventions. This talk outlines the distinction between this “indirect” approach and one that more directly evaluates the health impacts of specific regulatory interventions. We describe ongoing projects related to the development of statistical methods for “direct” accountability assessment of the effectiveness of interventions, with a focus on studies that attempt to combine statistical methods for causal inference with (possibly simplified) knowledge of atmospheric processes. We illustrate with a source-oriented approach to estimating the association between coal power plant emissions and IHD hospitalizations among Medicare beneficiaries, and also outline ongoing statistical methods work for settings where pollution transport yields the setting of so-called “interference” between observations.

 

Philip henry de frahan (FALL 2017)

Philip Henry de Frahan leads Global Business Development for Enernet Global in its markets: Australia, Philippines, and the Caribbean. Prior to joining Enernet, Philip managed 300MW of distributed generation (solar, storage, microgrids, V2G, back-up diesel generation, and demand response) at NRG. This followed his first job at Eos Energy Storage, a grid-scale energy storage technology developer. Philip graduated with a CEMS Master in International Management from the Louvain School of Management and the Graduate School of St. Petersburg, Russia. 

Presentation Abstract: Building a Renewable Energy Business in a Developing Country

With limited transmission and distribution infrastructure and an economy growing at 7%, the Philippines desperately needs cheaper and more reliable power. On one hand, many community islands depend on expensive, and polluting diesel generation for 12-16 hours of power a day. In addition to hampering health and education, this leaves them at the mercy of spotty fuel deliveries, and exposed to the volatility of fuel prices. On the other hand, grid-connected businesses suffer from brown-outs and poor power quality that damage expensive equipment.

Enernet Global, a renewable energy development and financing startup based in New York, recognized the opportunity to move in this market. Creating a business from scratch involves consideration of market selection, market entry, local hiring, corruption, deal-making in renewables, and more.

Radhika Khosla, Ph.D. (FALL 2017)

Radhika Khosla is a Fellow at the Center for Policy Research in India. She is a Visiting Scholar at MIT’s Energy Initiative, and a Visiting Scholar at the Kleinman Center for Energy Policy, University of Pennsylvania in the fall of 2017. She works on the integrated nature of India’s energy sector to examine the linkages between energy, development and climate change, particularly in urban areas. She also focuses on the demand-side of Indian energy, with attention to the technological, institutional and behavioral aspects of energy use and its lock-in to a rapidly growing built environment. In addition, her work examines the analytic and strategic dimensions of India’s energy and climate policies.

Presentation Abstract: Examining energy services in Indian households

Demand-side measures, such as energy management in buildings, are central to addressing global climate change. The window of opportunity to maximize these measures is particularly important in the developing country of India, which is at the brink of unprecedented urban transitions. It is estimated that two-thirds of India’s commercial and high-rise building stock in 2030 will be built in the next 15 years, and the path-dependency from the lifespans of new buildings makes the carbon lock-in risk higher in India than anywhere else. At the same time, the early stages of India’s buildings stock provides an opportunity to examine and inform practices that will significantly influence the country’s energy, development, and climate change agenda. This presentation aims to establish residential building electricity use as central to demand-side mitigation in India’s rapidly urbanizing cities. Based on large-scale surveys undertaken in 2016-17, the work will provide empirical evidence for: (1) the energy efficient lighting transition taking place in urban India; (2) an “appliance ladder” which demonstrates which appliances people buy, and at what stage during their transitions to higher consumption levels; and (3) establish the significant role of behavior in energy services consumption. In sum, this work lays forth new knowledge on mitigation pathways in Indian urban residences, and in doing so identifies gaps and opportunities to stimulate a socio-technical research agenda for India’s buildings stock.

 

wei peng, Ph.D. (FALL 2017)

Wei is a Giorgio Ruffolo Postdoctoral Research Fellow in Sustainability Science in the Belfer Center for Science and International affairs at the J.F. Kennedy School of Government, Harvard University. Her research utilizes modeling tools to inform energy policy in both emerging markets (e.g. China) and developed countries (e.g. U.S.) to align their decarbonization efforts with local environmental and socioeconomic concerns. She also connects these local impacts of decarbonization with the public opinion on carbon policies. She holds a Ph.D. in Public Policy from the Woodrow Wilson School of Public and International Affairs at Princeton University, and a B.S. in Environmental Sciences from Peking University. 

Presentation Abstract: Air quality and water implications of power sector decarbonization: Effects of strengthening environmental policies

Global climate change and local environmental issues are both heavily impacted by power sector decisions. Decarbonizing the power sector can bring air quality co-benefits, while its water implications depend on the choices of low-carbon technologies (e.g. nuclear generation can be water-intensive). Using China’s 2030 power system design as a test case, we demonstrate that strengthening the air quality or water policy in isolation (e.g. increasing air pollution or water price) can lead to a trade-off between air quality and water conservation benefits of decarbonization at the national level, as well as uneven regional impacts at the subnational level. This is because air-pollution-oriented and water-oriented transmission system designs can be different, due to the regional variations in low-carbon deployments, air pollution and water scarcity. Therefore, integrating both air pollution and water concerns into power sector strategies is critical to simultaneously address local and global sustainability challenges.

Presentation Abstract:  Charging ahead: Prepaid electricity metering in South Africa

The standard approach to recovering the cost of electricity provision is to bill customers monthly for past consumption. If unable to pay, customers face disconnection, the utility loses revenue, and the service provision model is undermined. A possible solution to this problem is prepaid metering, in which customers buy electricity upfront and use it until the prepaid amount is consumed. We use data from Cape Town, South Africa to examine the effects of prepaid electricity metering on residential consumption and returns to the electric utility. Over 4000 customers on monthly billing were involuntarily assigned to receive a prepaid electricity meter, with exogenous variation in the timing of the meter replacement. Electricity use falls by about 13 percent as a result of the switch, a decrease that persists for the following year. This creates a tradeoff for the utility: revenue from consumption falls but more of it is recovered on time and at a lower cost. The benefits to the electric utility outweigh the costs, on average, though results are very heterogeneous. Poorer customers and those with a history of delinquent payment behavior show the greatest improvement in profitability when switched to a prepaid meter. These findings point to an important role for metering technologies in expanding energy access for the poor.
