The Harvard Project on Climate Agreements has released a volume of 26 briefs that explores a range of topics related to how we might govern the deployment of solar geoengineering.

The Iran nuclear deal was officially implemented on Saturday, as Iran successfully fulfilled its initial key nuclear commitments and the international community relieved major sanctions, including unfreezing about $100 billion of Iranian money. Implementation Day was met with applause from deal supporters in the U.S. and Iran, while critics have raised questions about whether Iran will adhere to its requirements and how it will flex its newfound economic power. Also in recent days, the U.S. and Iran agreed to a prisoner swap that led to the freedom of Washington Post reporter Jason Rezaian and others, and negotiated the release of American sailors detained in Iran. What does the arrival of Implementation Day mean for Iran’s nuclear program and nuclear nonproliferation, and how does it bode for the future of U.S.-Iran relations? We asked Belfer Center experts to weigh in on these and related questions.

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.

The report, Transforming U.S. Energy Innovation, released on Nov. 22, 2011,is the result of a three-year energy research, development, demonstration, and deployment (ERD3) project of the Energy Technology Innovation Policy (ETIP) research group at Harvard Kennedy School's Belfer Center for Science and International Affairs. The ERD3 project was funded by a grant from the Doris Duke Charitable Foundation to produce and promote a comprehensive set of recommendations to help the U.S. administration accelerate the development and deployment of low-carbon energy technologies.

"The WikiLeaks cables reveal an episode in which officials in Yemen — home of al Qaeda's most active regional branch — warned that a deadly radioactive source was sitting in building whose only guard had left and whose sole security camera had long been broken. These programs provide the practical means to deal with such threats."

"The focus of the workshop was on the demonstration stage of the technology innovation cycle. Current policies do not adequately address the private sector’s inability to overcome the demonstration "valley of death" for new energy technologies. Investors and financiers fear that the technology and operational risks at this stage of the cycle remain too high to justify the level of investment to build a commercial-sized facility."

"There is broad political consensus that the current energy system in the United States is unable to meet the nation's future energy needs, from the security, environment, and economic perspectives. New energy technologies are required to increase the availability of domestic energy supplies, to reduce the negative environmental impacts of our energy system, to improve the reliability of current energy infrastructure (e.g., smart grid, energy storage), and to increase energy efficiency throughout the economy."

Matthew Bunn testified to the "Blue-Ribbon Commission on the Nuclear Future" on Tuesday May 25, 2010, presenting testimony entitled "Managing Spent Fuel and Nuclear Waste Successfully—What Needs to Be Done?"

This analysis provides an overview the Department of Energy's fiscal year 2011 energy research, development, demonstration, and deployment (ERD3) budget proposals, and lays out actionable recommendations to strengthen the effort.  Overall, the report concludes that the 7 percent requested increase in applied energy research, development, and demonstration funds, while welcome in a time of budget stringency, remains well short of the sustained investment likely to be needed to meet the energy demands of the 21st century.
