Monday, November 4, 2013 | 04:15 PM - 05:15 PM | NVIDIA Auditorium, Jen-Hsun Huang Engineering Center | Free and Open to All
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.

What does the future of energy really hold? Join Scott Tinker on a spectacular global adventure to find out. Scott explores the world’s leading energy sites, from coal to solar, from oil to biofuels. Many of these sites are highly restricted and never before seen on film. Scott gets straight answers from the people driving energy today, international leaders of government, industry and academia. In the end, he cuts through the confusion to discover a path to our future that is surprising and remarkably pragmatic.
"Switch" is a balanced documentary, embraced and supported by people all along the energy spectrum – fossil and renewable, academic and environmental.

By the end of the 20th century, the United States had about 15,000 wastewater treatment plants and 13,000 landfills. These systems were designed to prevent environmental harm and to protect public health. Other factors, such as energy costs and climate change, were not a consideration. Waste and wastewater were collected, transported to centralized facilities, treated to remove harmful agents, and the effluents and residuals discharged. Now these systems have reached their design life and are in need of revitalization. Energy costs, climate change, and demand for secure supplies of water, food and materials provide powerful incentives for technological innovation through the creation of circular markets. In such markets, wastewater becomes a resource for local production of freshwater and nutrients, and organic waste becomes feedstock for local production of energy and biomaterials. Many groups around the world are now developing technology to enable such innovation.

Abstract from Dr. David Stern:
Challenges to Meet a Low Carbon Fuel Standard (LCFS)
As part of AB32, California’s Climate Change Act, the California Air Resource Board (CARB) has enacted a Low Carbon Fuel Standard. The LCFS mandates a reduction in fuel life-cycle carbon intensity (CI), versus a petroleum fuel (gasoline/diesel) baseline. At low CI reduction targets, increased use of biofuel is needed to meet the target, but higher CI reduction targets (e.g., 10%) are infeasible without large numbers of electric vehicles, large use of very low CI biofuels, or both.
This talk will review the challenges in meeting the LCFS, and why LCFS is a complex, cost ineffective, and non-transparent policy to reduce GHG’s.
- On a cost per unit GHG reduction, transportation-fuel-related cost reductions substantially exceeds the cost of other GHG reductions
- If policy goals are to promote biofuels or to electrify the fleet, direct and transparent regulations are better ways to meet these goals
- If the policy goal is GHG reduction, the most efficient and cost effective approach is a broad based, revenue-neutral carbon tax
Our discussion will also review principles to consider in policy development. If society chooses to implement climate policy, such policies should: ensure a uniform and predictable cost of GHG emissions, let market prices drive the solution, minimize complexity, maximize transparency, and adjust to future developments in climate science and the economic impacts of climate policies.

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.

Essentially all sustainable energy systems rely on the energy influx from the sun. In order to store solar energy it is most conveniently transformed into a chemical form, a fuel. The key to provide an efficient transformation of energy to a chemical form is the availability of suitable catalysts, and we will need to find new catalysts for a number of processes if we are to successfully synthesize fuels from sunlight. Insight into the way the catalysts work at the molecular may prove essential to speed up the discovery process. The lecture will discuss some of the challenges to catalyst discovery, the associated challenges to science as well as some approaches to molecular level catalyst design. Specific examples will include the (photo-)electrochemical oxygen evolution and hydrogen evolution reactions, carbon dioxide reduction, and biomass transformation reactions.

National Academy of Sciences Report: America's Energy Future: Liquid Transportation Fuels from Coal and Biomass
The volatility of oil prices, the large proportion of oil importation, and the massive contribution of greenhouse gases from the transportation sector motivates the United States to seek domestic sources of alternative transportation fuels with lower greenhouse emissions. The abundance of coal and biomass in the United States makes them attractive candidates to provide alternatives to petroleum-based liquid fuels. However, there are important questions about the economic viability, carbon impact, and technology status of these options.
The National Research Council report Liquid Transportation Fuels from Coal and Biomass: Technological Status, Costs, and Environmental Impacts provides a snapshot of the potential costs of liquid fuels from biomass by biochemical conversion and from biomass and coal by thermochemical conversion. The report concluded that alternative liquid transportation fuels from coal and biomass have the potential to play an important role in helping the United States address issues of energy security, supply diversification, and greenhouse-gas impacts. The various options have different greenhouse gas impacts, and the choices will most likely depend on U.S. carbon policy. Cellulosic ethanol, coal-to-liquid fuels, and coal and biomass to liquid fuels can be available commercially in the 2020 time frame if large-scale demonstrations of the conversion technologies are pursued aggressively in the next few years.
