Spatial Energy Efficiency Patterns in New York and Implications for Energy Demand and the Rebound Effect. By Joseph Nyangon and John Byrne. Energy Sources, Part B: Economics, Planning, and Policy (Submitted). [Forthcoming]. (2021).

This study uses a spatial Durbin error model (SDEM) approach to analyze adoption trends for residential energy efficiency measures (EEMs) in New York state. Model results are based on socioeconomic, building, and household demographic characteristics during the 2012-2016 period. Our study’s results confirm that a positive correlation exists between EEM uptake and multifamily buildings, gas-heated homes, education effects, and spatial spillover effects among neighboring ZIP codes. The results show that building attributes hold a relatively high explanatory power over EEM adoption compared with socioeconomic characteristics. Our results show that energy efficiency policies can create positive and significant neighborly effects in promoting EEM adoption. The developed SDEM methodological framework can provide useful insights on various energy efficiency opportunities that exist in rural, suburban, and urban communities, highlighting the need to review policy incentives periodically to address underlying changes in the built environment and spatial disparities in energy efficiency investments.

Estimating the Impacts of Natural Gas Growth on Solar Electricity Generation: A Case Study of Experience in the PJM Territory. By Joseph Nyangon and John Byrne The Energy Journal (Submitted). [Forthcoming]. (2021).

This paper investigates the impact of increasing natural gas-fired electricity generation assets on installed distributed solar PV systems in the PJM Interconnection in the United States over the period 2008-2018. We present an empirical dynamic panel data model using the system generalized method of moments (system-GMM) estimation approach. The model accounts for the impact of past and current policy and market structure changes over time, forecasting errors, and business cycles by controlling for the location of generation assets and year fixed effects. Using an instrumental variable to control for endogeneity, we find evidence of complementarity of investments in flexible natural gas-fired technologies and distributed solar generation capacity for the decarbonization process in the PJM territory; however, we also find considerable heterogeneity. Such heterogeneity is displayed in the relationship between distributed PV and average electricity prices in different states. More interestingly, we find no evidence suggesting any relationship between the growth in distributed solar PV and the share of nuclear energy capacity, electricity consumption, or the percentage of hydro, coal-fired, and other less-efficient fossil power plants. In addition, we assess the effects of federal policies, state renewable portfolio standard-driven solar renewable energy certificates, net-metering, differences in market structure, and other demand and cost-related factors. Considering these empirical findings, we discuss policy implications and recommendations, including energy storage as a non-wire alternative policy tool for enabling optimal distributed solar deployment.

American Policy Conflict in the Greenhouse: Divergent Trends in Federal, Regional, State, and Local Green Energy and Climate Change Policy, Redux. By John Byrne, Job Taminiau and Joseph Nyangon [Forthcoming]. (2021).

The U.S. Government, led by the Trump Administration, has rejected participation in the Paris Agreement on Climate Change. Hostility towards sustainable energy and climate change policy by the Administration continues to fuel existing global perceptions that the U.S. is not acting in substantial ways to address climate change. This paper continues an investigation started over ten years ago (Byrne et al., 2007) that documented that, nevertheless, action within the U.S. is indeed moving forward and concluded that states, cities, and local innovation are filling the leadership vacuum created by the abdication of responsibility at the federal level. To gauge the strength of this movement, the 2007 analysis estimated that the combined effort of these subnational actors could reduce the increase in business-as-usual carbon dioxide emissions by as much as 65%. This paper reviews the diverse policies, strategies, and cooperative frameworks taking place at the regional, state and local levels to guide climate protection.

An Assessment of Price Convergence Between Natural Gas and Solar Photovoltaic in the U.S. Electricity Market. By Joseph Nyangon, John Byrne and Job Taminiau. WIREs Energy and Environment. Volume 6, Issue 3. May/June 2017.

Shale gas boom in Pennsylvania is a major driver of strong growth in natural gas production in counties such as Washington, Bradford, and Susquehanna with positive effects on (a) gas spot prices, (b) wages and local business activity, and (c) economic diversification and infrastructure development. A multidimensional market perspective is applied to study natural gas and solar PV markets in the United States for evidence of price convergence and integration using Phillips‐Sul convergence test and Kalman filter time‐varying analysis as well as assessing the performance of MAC Global Solar Energy Index (SUNIDX) and S&P GSCI (natural gas) indices. Modeled LCOE for solar PV and natural gas systems average 12.95¢/kWh and 9.5¢/kWh, respectively. Abstract | Full Text | PDF | References

The U.S. Shale Gas Revolution and its Implications for International Energy Policy. By Joseph Nyangon. Green Monitor: Technology Policy Review (GREEN School). 2015.

The shale gas revolution has fundamentally transformed energy markets domestically and abroad. Rising production has led to falling gas and oil prices in the U.S., while Europe, in contrast, is paying four to five times more for its natural gas and becoming one of the biggest importers of U.S. coal. As recently as five or six years ago this turnabout seemed improbable, with many analysts calling for rapid growth in renewable energy investment as the best means by which to wean the nation from its dependence on imported oil. Even then, such investment seemed far-fetched as the liquidity crisis worsened during the 2008-2012 global recession, forcing the federal government to institute stringent fiscal and monetary stimulus to stabilize the financial market and institutions. Taken together, the shale gas revolution represents the maturation of industry-friendly policies started under President Bush and continued during the Obama Administration. These policies supported the introduction of advanced technologies such as hydraulic fracturing, tight-oil extraction, horizontal drilling, innovative industrial software and other digital solutions, which have allowed production companies to economically extract oil and gas from previously inaccessible or financially infeasible shale rock formations with breathtaking speed. Most tantalizingly, this is a story of the triumph of a combination of economics of energy (operating by its own rules of supply and demand), the power of government-funded research and development (R&D), and getting the relationship right between the government and private sectors. [PDF]

International Environmental Governance: Lessons from UNEA and Perspectives on the Post-2015 Era. By Joseph Nyangon. Journal of Sustainable Development Law and Policy. 2014. ISSN: 2467-8392.

This paper reviews the outcome of the inaugural meeting of the United Nations Environment Assembly (UNEA), while developing a political economy account of how institutional arrangements of international environmental governance has impeded effective environmental reform. Multilaterally, international environmental governance continues to exhibit elements of complexity, fragmentation, lack of coordination as well as redundancy. In more critical terms, lack of policy integration between environmental regimes is a concern of environmental governance that the new UNEA should address as a matter of priority. Furthermore, incoherent policy objectives in international environmental law often characterized as a governance patchwork have been criticized for their economic orthodoxies that only serve to marginalize and delegitimize alternative modes of environmental governance. In this regard, a core part of UNEA’s institutional legitimacy depends on its success in coevolving to keep up with environmental challenges as they themselves change, as well as enhancing consensus-based stakeholder engagement, perspectives, and participation on environmental governance. This will be its true litmus test on how it responds coherently and effectively to international environmental governance in a post-2015 development world.

Smart Energy Frameworks for Smart Cities: The Need for Polycentrism. By Joseph Nyangon. In Handbook of Smart Cities, Augusto, JC. (Ed.). London, UK: Springer International. (2021).

Rapid growth in megacities has prompted deep transformations intended to change sociotechnical systems, deep social and institutional practices, and scientific inquiries to better understand energy and material flows of cities. Typically, these processes are defined by sociotechnical experimentation and purposive re-shaping of the synergies between jurisdictions, sectors, and technical solutions required to optimize resource management and improve institutional diversity and its configurations. This chapter studies features of smart energy frameworks for smart cities leadership in an attempt to ignite transformations in energy business models for sustainability systems from the bottom up. Following this polycentric approach, the chapter documents seven emerging models for smart city energy governance, namely distributed energy resources development, energy storage, microgrids, demand response and energy management systems, smart measuring systems, energy harvesting, and green technology innovations. One observation is that while Singapore and Shanghai are a product of advanced polycentric strategic planning, the urban developments around the greater Jakarta area is an outcome of gradual alignments and reconfigurations of urban design toward the polycentric goal. In addition, energy systems and utility business models are changing simultaneously in several cities with respect to institutional contexts, urban planning, and customer choice. A key message of this chapter is that capturing the impacts of this urban transformation across the quartiles of energy resource development, technological progress, and policy stringency requires the design and implementation processes that simultaneously promotes polycentric authority and contributes to informed understanding of the scale and consequences of these transitions.
