During the early stages of Pennsylvania's coal-to-gas transition, extraction and generation of coal and natural gas contributed to a yearly 2.6–8.4% increase in the state's water consumption. Although some areas experienced no change in water consumption, others experienced large decreases or increases. Consumption variations depended on available natural gas resources and pre-existing power-generating infrastructure. This analysis estimates monthly water consumption associated with fuel extraction and power generation within Pennsylvania watersheds between 2009 and 2012. It also provides the first comprehensive representation of changing water consumption patterns associated with the state's coal-to-gas transition at the sub-basin level.

The Energy Technology Innovation Policy research group at the Harvard Kennedy School and the Tsinghua School of Public Policy and Management convened a workshop at Tsinghua University in Beijing on June 18–19, 2015 to build on the momentum created by the U.S.-China joint emissions agreement and the upcoming Paris negotiations. The objective of the Workshop was to discuss the current state of affairs in China, in the United States, and in selected other countries as well as academic research on: (1) the funding and allocation of government investments in R&D, with a particular focus in energy; (2) the impact of policy on private sector innovation in energy; and (3) the management of publicly funded R&D organizations.

The promise, prospects, and public policy trade-offs related to second-generation biofuels in road transport were addressed in an executive session convened at The Henry Ford Museum in Dearborn, Michigan, on April 7 and 8, 2015. The workshop brought together twenty-eight of the world's leading experts from the fields of policy, science, and business for an intensive two-day session. This report is a summary of the main points and issues raised over the two days. It has been reviewed by all the participants. The summary is intended to reflect the breadth of the discussion, rather than to suggest any form of overall consensus among the participants.

The promise, prospects, and public policy trade-offs related to the greater use and production of second-generation biofuels were addressed in an executive session convened by the Harvard Kennedy School on November 13 and 14, 2014. The session attracted more than 25 of the world's leading experts from the fields of policy, science, and business for an intensive two day session. The agenda consisted of three sessions focused on (i) the sustainability of cellulosic supply chains, (ii) government policy options to attract investment and (iii) government policy options to ensure that environmental objectives are met.

The authors present a new modeling framework for studying optimal generating capacity and public RD&D investments in the electricity sector under decision-dependent RD&D uncertainty and learning.

Characterizing the future performance of energy technologies can improve the development of energy policies that have net benefits under a broad set of future conditions. In particular, decisions about public investments in research, development, and demonstration (RD&D) that promote technological change can benefit from (1) an explicit consideration of the uncertainty inherent in the innovation process and (2) a systematic evaluation of the tradeoffs in investment allocations across different technologies. To shed light on these questions, over the past five years several groups in the United States and Europe have conducted expert elicitations and modeled the resulting societal benefits. In this paper, the authors discuss the lessons learned from the design and implementation of these initiatives.

The unconventional fossil fuel extraction industry—in the U.S., primarily shale gas and tight oil—is expected to continue expanding dramatically in coming decades as conventionally recoverable reserves wane. At the global scale, a long-term domestic supply of natural gas is expected to yield environmental benefits over alternative sources of fossil energy. At the local level, however, the environmental impacts of shale gas and tight oil development may be significant. The development of technology, management practices, and regulatory policies that mitigate the associated environmental impacts of shale gas development is quickly becoming the next frontier in U.S. unconventional fossil resource extraction.
