Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

Washington Post reporter Jason Rezaian recounts his 544 days in an Iranian prison during a talk with R. Nicholas Burns of the Harvard Kennedy School.

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.

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.

In order to make R&D funding decisions to meet particular goals, such as mitigating climate change or improving energy security, or to estimate the social returns to R&D, policy makers need to combine the information provided in this study on cost reduction potentials with an analysis of the macroeconomic implications of these technological changes. The authors conclude with recommendations for future directions on energy expert elicitations.

"In addition to U.S. moves toward curbing carbon emissions, international attention on the issue is far more substantial than it was at the time of the 1997 Kyoto Protocol, according to panelists. That agreement covered just 14 percent of global carbon emissions, Stavins said. Countries responsible for 90 percent of today's emissions have already committed to voluntary reductions in advance of the Paris talks."

High cost and technical immaturity of bulk (multi-hour) electricity storage (BES) systems are often cited as major hurdles to increasing the penetration of intermittent renewables. The authors use a simple model to assess the economics of BES under carbon emissions constraints.

Iran’s top nuclear negotiator was heading back to Tehran on Sunday to consult with his nation’s leadership, as negotiators remained divided over how to limit and monitor Tehran’s nuclear program and even on how to interpret the preliminary agreement they reached two months ago.

On 22 November 2013, the Federal Energy Regulatory Commission approved the latest version of mandatory cybersecurity regulations for the bulk electric system—known as Critical Infrastructure Protection (CIP) Reliability Standards. The CIP standards are relatively unique: they are developed through an unusual model of industry-led regulation that places industry, and not federal regulators, at the center of regulatory design and enforcement. The CIP regulations have received a significant amount of criticism. Critics argue that the regulations are incomplete at best and irreparably flawed at worst. The author examines the lessons we can learn from the CIP standards and poses a provocative question: Are the regulations actually a secret success?
