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.

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.

The United States and the world need a revolution in energy technology—a revolution that would improve the performance of our energy systems to face the challenges ahead. In an intensely competitive and interdependent global landscape, and in the face of large climate risks from ongoing U.S. reliance on a fossil-fuel based energy system, it is important to maintain and expand long-term investments in the energy future of the U.S. even at a time of budget stringency. It is equally necessary to think about how to improve the efficiency of those investments, through strengthening U.S. energy innovation institutions, providing expanded incentives for private-sector innovation, and seizing opportunities where international cooperation can accelerate innovation. The private sector role is key: in the United States the vast majority of the energy system is owned by private enterprises, whose innovation and technology deployment decisions drive much of the country's overall energy systems.

For the past forty years, United States Presidents have repeatedly called for a reduction in the country's dependence on fossil fuels in general and foreign oil specifically. Some officials advocate the electrification of the passenger vehicle fleet as a path to meeting this goal. The Obama administration has embraced a goal of having one million electric-powered vehicles on U.S. roads by 2015, while others proposed a medium-term goal where electric vehicles would consist of 20% of the passenger vehicle fleet by 2030 — approximately 30 million electric vehicles. The technology itself is not in question; many of the global automobile companies are planning to sell plug-in hybrid electric vehicles (PHEVs) and/or battery electric vehicles (BEVs) by 2012. The key question is, will Americans buy them?

This paper proposes a framework for a liability regime for geological sites for sequestration of carbon dioxide. It incorporates issues that were discussed at the the June 21, 2010 Expert Workshop Addressing CCS Liability, Oversight, and Trust Fund Issues.

Harvard Law School’s Emmett Environmental Law and Policy Clinic* supports immediate large-scale carbon capture and sequestration (“CCS”) demonstration projects as part of a larger national and global effort to address climate change. Large-scale CCS projects (those that sequester at least 1.5 million tons of captured carbon dioxide (“CO2”) annually) must be demonstrated soon to confirm CCS as a viable strategy to combat climate change and to show the commitment of the United States to achieving meaningful reductions in domestic CO2 emissions.

This paper summarizes the discussions from a workshop convened by the Harvard Law School's Emmett Environmental Law & Policy Clinic in Washington, DC on June 21, 2010.

There is broad consensus in scientific, business, and political circles that carbon capture and sequestration ("CCS") must be demonstrated quickly on a large scale because it is likely to be an important technology for reducing carbon dioxide ("CO2") emissions throughout the world. Indeed, a number of commentators predict that it may be impossible to achieve significant emissions reduction in the United States and abroad without the use of CCS.
