Governance of Highly Decentralized Nonstate Actors: the Case of Solar Geoengineering

| November 2018

We here introduce the idea of highly decentralized solar geoengineering, plausibly done in form of small high-altitude balloons. While solar geoengineering has the potential to greatly reduce climate change, it has generally been conceived as centralized and state deployed. Potential highly decentralized deployment moves the activity from the already contested arena of state action to that of environmentally motivated nongovernmental organizations and individuals, which could disrupt international relations and pose novel challenges for technology and environmental policy. We explore its feasibility, political implications, and governance.

Changing Carbon Content of Chinese Coal and Implications for Emissions of CO2

| September 2018

The changing carbon content of coal consumed in China between 2002 and 2012 is quantified using information from the power sector. The carbon content decreased by 7.7% over this interval, the decrease particularly pronounced between 2007 and 2009. Inferences with respect to the changing carbon content of coal and the oxidation rate for its consumption, combined with the recent information on coal use in China, are employed to evaluate the trend in emissions of CO2. Emissions are estimated to have increased by 158% between 2002 and 2012, from 3.9 Gt y-1 to 9.2 Gt y-1.

Climate, Air Quality and Human Health Benefits of Various Solar Photovoltaic Deployment Scenarios in China in 2030

Solar photovoltaic (PV) electricity generation can greatly reduce both air pollutant and greenhouse gas emissions compared to fossil fuel electricity generation. The Chinese government plans to greatly scale up solar PV installation between now and 2030. However, different PV development pathways will influence the range of air quality and climate benefits. Benefits depend on how much electricity generated from PV is integrated into power grids and the type of power plant displaced. Using a coal-intensive power sector projection as the base case, the authors estimate the climate, air quality, and related human health benefits of various 2030 PV deployment scenarios.

Electrification with decarbonized electricity is a central strategy for carbon mitigation. End-use electrification can also reduce air pollutant emissions from the demand sectors, which brings public health co-benefits. In this article, the authors focus on electrification strategies for China, a country committed to both reducing air pollution and peaking carbon emissions before 2030. Considering both coal-intensive and decarbonized power system scenarios for 2030, they assess the air quality, health, and climate co-benefits of various end-use electrification scenarios for the vehicle and residential sectors relative to a non-electrified coal-intensive business-as-usual scenario.

Potential Arbitrage Revenue of Energy Storage Systems in PJM

| 2017

The volatility of electricity prices is attracting interest in the opportunity of providing net revenue by energy arbitrage. The authors analyzed the potential revenue of a generic Energy Storage System (ESS) in 7395 different locations within the electricity markets of Pennsylvania-New Jersey-Maryland interconnection (PJM), the largest U.S. regional transmission organization, using hourly locational marginal prices over the seven-year period 2008–2014.

Driving Force or Forced Transition?: The Role of Development Cooperation in Promoting Energy Transitions in the Philippines and Morocco

| August 2016

This article contributes to the understanding of transitions towards low carbon societies in the developing world. While adding extensive empirical insights from the status of energy transitions in two countries faced with major energy challenges, the Philippines and Morocco, the authors contribution enquires what role external actors like international donors in general, and Germany in particular, can play in such transitions.

Quantifying the Effects of Expert Selection and Elicitation Design on Experts' Confidence in Their Judgments About Future Energy Technologies

| 2016

Expert elicitations are now frequently used to characterize uncertain future technology outcomes. However, their usefulness is limited, in part because: estimates across studies are not easily comparable; choices in survey design and expert selection may bias results; and overconfidence is a persistent problem. The authors provide quantitative evidence of how these choices affect experts' estimates.

DOE Budget Authority for Energy Research, Development, & Demonstration Database

| March 2016

This document contains March 2016 updates to our database on U.S. government investments in energy research, development, demonstration, and deployment (ERD3) through the Department of Energy. The database, in Microsoft Excel format, tracks DOE appropriations from FY 1978–2016 and the 2017 budget request and includes funding for ERD3 from the American Recovery and Reinvestment Act of 2009. It also includes several charts.
