Through systematic reviews and original research, this presentation will review evidence of environmental impacts of renewable electricity generation technologies compared, where possible, to their conventional incumbents. Evidence for greenhouse gas emissions, water and land use will be reviewed mostly from the perspective of life cycle assessment. Areas of uncertainty will be highlighted as suggestions for future research.

Because electricity is a necessary input to so many economic activities, there are significant political obstacles to charging business and residential customers retail prices that reflect the hourly wholesale price of electricity. A long history of retail electricity prices that do not vary with real-time system conditions makes this task even more difficult. Finally, the lack of interval meters on the customer’s premises makes it impossible to determine precisely how much energy each customer withdraws in a given hour.
Recently a number of jurisdictions in the U.S. have installed the interval meters necessary for customers to participate actively in the wholesale market. This talk will summarize the results of a number of research projects at the Program on Energy and Sustainable Development for allowing electricity consumers to benefit from active participation in wholesale electricity markets. The results of dynamic pricing and information provision experiments will be summarized, and current and future directions for research at the Program on Energy and Sustainable Development will be described. Necessary changes in state-level regulatory policies that can also unlock the economic benefits of modern technologies for active participation of final consumers will also be discussed.

In many of the challenges faced by the modern world, from overcrowded road networks to overstretched healthcare systems, large benefits for society come about from small changes by very many individuals. Researchers in the societal networks group at Stanford University are running a series of pilot projects aiming to develop principles for inducing small changes in behavior in networks such as transportation, wellness, energy and recycling. Pilots have been conducted with Infosys Technologies in Bangalore on commuting and with Accenture-USA on wellness. Two others are ongoing: public transit congestion in Singapore, and traffic congestion and parking at Stanford.
In this talk, Balaji Prabhakar will describe this work and present results from the pilots. Some salient themes are the use of low-cost sensing and networking technology for sensing individual behavior, and the use of incentives and social norming to influence behavior.

A combination of policy measures and reduced costs have driven a rapid growth in global installed capacity of solar photovoltaics. This rapid growth has prompted concerns over the net energy yield of PV energy production. Mik will analyze the energy balance of the PV industry given historic and projected growth in capacity. Results suggest that, despite the large amount of energy required to manufacture and install PV systems, there is a high likelihood (greater than 80%) that the industry became a net provider of electricity between 2009 and today. If current trends continue, the industry will almost certainly be a net electricity producer by 2015 and will have ‘paid back’ the energy subsidy required for its early growth by the end of this decade. This analysis raises a number of implications for PV research, development and deployment including: further reducing the energy embodied within PV systems, including balance of system components; designing more efficient and durable systems; and deployment in regions that will achieve high capacity factors.

It is now clear that enormous quantities of natural gas can be produced from organic rich shales found in many countries throughout the world. Because natural gas is both a flexible fuel and much cleaner than other fossil fuels, it has the potential to significantly transform energy use in many regions. Natural gas used for electrical power generation produces about half as much CO2 as coal.
Despite these advantages, there are also significant challenges associated natural gas development. These include minimizing the impact of shale gas development on the environment and communities. In the U.S. alone, thousands of wells will need to be drilled each year (along with construction of pipelines, compressor and distribution facilities, etc.). While a number of misleading claims have been made about the dangers associated with processes such as hydraulic fracturing, poor well construction and drilling have the potential to cause environmental damage which must be minimized.
Another challenge associated with shale gas development is to significantly improve the efficiency of drilling and production practice. This will require greatly improved understanding of shale gas production from the nano-scale pore structure and flow mechanisms in the shale to the optimal way to stimulate production using horizontal drilling and multi-stage hydraulic fracturing.

In little more than a decade, carbon dioxide (CO2) capture from point source emissions and sequestration in deep geological formations has emerged as one of the most important options for reducing CO2 emissions. Two major challenges stand in the way of realizing this potential: the high cost of capturing CO2, and gaining confidence in the capacity, safety and permanence of sequestration in deep geological formations. Building on examples from laboratory and field-based studies of multiphase flow of CO2 in porous rocks; this talk addresses the current prospects for CO2 sequestration.
Which formations can provide safe and secure sequestration? At what scale will this be practical and is this scale sufficient to significantly reduce emissions? What monitoring methods can be used to provide assurance that CO2 remains trapped underground? What are the long-term risks of geological sequestration and how can they be managed? The status of each these questions will be discussed, along with emerging research questions.

Nobel Laureate Burton Richter and New York Times journalist Matthew Wald will discuss what is happening in Japan and what it means for nuclear power. Mr. Wald will describe the sequence of events that occurred at the Fukushima nuclear plants following the earthquake in Japan. Dr. Richter will cover the technical issues of what happens in a nuclear reactor under these circumstances. Dr. Richter will review the current use of nuclear power worldwide and the main issues that nuclear regulators must address when assessing risk in disaster scenarios. Mr. Wald will describe the nuclear renaissance before and after Fukushima and report on what he has been hearing from legislators, regulators, industry experts, and the public. Mr. Wald and Dr. Richter will provide their perspectives on the future of nuclear power.

In parallel with his research in Indoor Environment, Dr. Gadgil has a long record of innovative solutions to problems in the developing world. He has pioneered the way to accelerate access to compact fluorescent lamps for poor households in developing countries; invented and commercialized a method to affordably disinfect drinking water for poor communities; designed, tested, and then found a way to build, field-test, and disseminate thousands of fuel-efficient stoves to refugee women in Darfur; and invented and is currently field-testing an extremely low cost, robust, and technically reliable method to remove arsenic from drinking water in Bangladesh and nearby regions.
