Nathaniel Horner and Inês Azevedo, with Arman Shehabi of LBNL, reviewed dozens of studies on the “indirect” energy effects of information and communication technology (ICT) services like e-commerce and telework. Though ICT has compelling energy savings potential, uncertainty in implementation details and higher-order effects make the actual net energy effect hard to calculate. http://tinyurl.com/Nat-Ines
ZERO EMISSIONS DAY: CHINA’S WIND ENERGY INFRASTRUCTURE
From the article:
“In December 2015, U.S. President Barack Obama and Chinese President Xi Jinping attended the United Nations’ 21st Climate Change Conference (UN COP21). The two presidents, representatives of the two largest producers of greenhouse gases on the globe, pledged to work together to establish a climate change agreement to mitigate the enormous impact greenhouse gases have had, and are having, on global warming.
“Thus, the Paris Agreement was formed. This agreement, the world’s first comprehensive climate agreement, is a pledge negotiated by the 196 countries in attendance at UN COP21 to reduce global greenhouse gas emissions by adopting renewable energy sources.
“In the wake of the Paris summit, engineering and public policy (EPP) Ph.D. student Long Lam studies China’s efforts to deploy renewable energy and mitigate its carbon emissions. Focusing on wind and solar energy, Lam studies China’s wind turbine innovation capabilities, dynamics within the solar photovoltaic industry, and the trajectories of various solar photovoltaic technologies in the marketplace.
“Lam recently published a paper, co-authored by EPP Associate Professor Inês Azevedo and Social and Decision Sciences’ Lee Branstetter, entitled “China’s wind electricity and cost of carbon mitigation are more expensive than anticipated.” The paper, published in Environmental Research Letters, discusses how China’s efforts to cut emissions from its coal power plants by 60% by 2020 have been slowed, despite a massive initiative to build up the country’s wind energy infrastructure.”

Stephanie’s dissertation was titled “Evaluating the Economic, Environmental and Policy Impacts of Ethanol as a Transportation Fuel in Pennsylvania.”
Nathaniel’s dissertation was titled “Powering the Information Age: Metrics, Social Cost Optimization Strategies, and Indirect Effects Related to Data Center Energy Use.”
Lawrence Berkeley National Laboratory, in collaboration with experts at Stanford, Carnegie Mellon, and Northwestern, today released our latest analysis of electricity used by data centers in the US. Surprisingly, electricity use in data centers has been roughly flat since the financial crisis with little growth projected to 2020, even though delivery of computing services has been increasing rapidly. As Iâ€™ve argued for years, the level of inefficiency in enterprise data center facilities leaves lots of room for improvement, and the market is finally getting that message.

Inês Azevedo provided a Colloquium titled “Understanding the Uncertainties in Consequences of Climate Change for the United States Power Sector Infrastructure when Considering a Realistic Mitigation Pace and Adaptation Needs” at ETH Zurich’s Institute for Atmospheric and Climate Science on the health, environmental and climate change effects of different interventions in the U.S. Electricity Grid. Given the broad audience of her seminars, other institutes and organizations have also requested additional seminars in the subject matter for the upcoming December.
Dr. Inês Azevedo, Associate Professor of Engineering and Public Policy, Co-Director, Climate and Energy Decision Making Center, Carnegie Mellon University provides an “Andy Talk” (20 minutes or less) on Energy Pathways, Policies, and Decisions during Carnegie Mellon’s Energy Week 2016.
Over 30 CEDM affiliates presented or moderated at the 33rd Annual USAEE conference, including Inês Azevedo and her students. Four out of the thirteen posters accepted to the conference were from Inês’ students. She moderated the session on Electric Vehicles: Studies on Pollution, Consumers, and Policies and was a co-author on nine of the presented. Brock Glasgo won the award for Best Poster and Nathaniel Horner won the award for Best Case Competition.
