EPP researchers find that charging electric vehicles at night can cause more harm than good
A new study, published in Environmental Science & Technology, EPP researchers Allison Weis, Jeremy Michalek, Paulina Jaramillo, and Roger Lueken find that allowing grid operators to throttle the speed at which electric vehicles charge can reduce costs, largely by shifting load to inexpensive coal-fired power plants available at night. But the health and environmental costs of the resulting air pollution outweighs operational cost savings in the PJM region, which includes Washington, D.C., Chicago, Philadelphia, and Pittsburgh. http://pubs.acs.org/doi/abs/10.1021/es505822f

Pennsylvania’s core forests are at risk of fragmentation from natural gas development
A research team in the EPP and CEE Departments at CMU including PhD student Leslie Abrahams, and professors Mike Griffin and Scott Matthews found fragmentation of core forests in Pennsylvania could as much as double due to Marcellus Shale development. This fragmentation largely results from pipeline development. However, strategically developing pipelines along existing roads rather than cutting new paths through forests could still enable complete development of the Marcellus Shale region without causing additional fragmentation. This could be done through a coordinated development plan, which would reduce pipeline redundancies, thereby simultaneously preserving core forest ecosystems while economically benefiting producers.

Storing energy may be profitable, but it¹s not a clean technology Adding energy storage to the electricity grid increases emissions, researchers find
Adding energy storage to the U.S. electricity grid results in increases in greenhouse gas emissions and local pollution from power plants, even if storage is charged from renewable energy, according to a team of researchers including EPP professor Inês Azevedo and EPP alum Eric Hittinger ‘12. Their findings, published in this week¹s issue of Environmental Science and Technology, report that an operating storage plant, such as the pumped hydro and compressed air plants already operating in the U.S., causes an average of 260 kilograms of carbon dioxide pollution for every megawatt-hour of electricity it provides. Storage plants also increase the amount of nitrogen oxide and sulfur dioxide pollution emitted in the U.S. http://pubs.acs.org/doi/abs/10.1021/es505027p
Azevedo asks, "How can we transition to sustainable energy systems?"
To transition to sustainable energy systems we need interdisciplinary research building on engineering, economics, and other social sciences. Should we invest in more energy efficient strategies? Are rebound effects an issue of concern? What are the environmental, health and climate change benefits of increasing renewables in the grid? How should we think about energy innovation? In this short video, EPP professor Inês Azevedo discusses some of her research and highlights key questions to lead us to sustainable energy systems. https://youtu.be/DHFgB0UdalU
Changing the renewable fuel standard to a renewable material standard
In a recently published paper EPP doctoral student Ira Daniel Posen and EPP professors Michael Griffin, Scott Matthews and Ines Azevedo investigate the greenhouse gas impact of expanding the scope of the U.S. Renewable Fuel Standard.

EPP study finds Chinese consumers may adopt electric vehicles first
A new study by EPP researchers finds that mainstream Chinese car buyers are more willing to adopt pure electric vehicles than American consumers. EPP professors Jeremy Michalek and Erica Fuchs, Ph.D. student John Helveston, and their co-authors surveyed automobile consumers in China and the U.S. to understand their preferences and willingness to pay for vehicle attributes. The research team asked prospective car buyers in China and the U.S. to choose among gasoline, hybrid, plug-in hybrid, and pure electric vehicles with varying range, performance, cost, brand, styling and recharging capabilities. Using statistical methods to infer which attributes were driving their choices, they found that, on average, American consumers are only willing to purchase a pure electric vehicle if it costs $10,000 to $20,000 less than an otherwise equivalent gasoline vehicle, depending on its range and recharging capabilities. In contrast, they found a smaller average disparity for Chinese consumers, who are willing to pay even more for pure electric vehicles if they have sufficient range and recharging capabilities. Both countries offer similar subsidies for plug-in vehicles, with the largest subsidies reserved for vehicles with large batteries, like pure electric vehicles. The study was recently published in the journal Transportation Research Part A: Policy and Practice.

Exporting liquefied natural gas can reduce global greenhouse gas emissions, but U.S. accrues social cost
A research team including Engineering and Public Policy PhD student Leslie Abrahams, and professors, Mike Griffin, and Scott Matthews found exporting liquefied natural gas from the U.S. can reduce global greenhouse gas emissions when substituting for coal or Russian natural gas abroad. However, while global emissions are reduced, emissions within the U.S. increase. Therefore, the U.S. incurs a social cost from exporting the natural gas. This social cost, along with other local environmental and social impacts from natural gas development, is important for the Department of Energy to consider when determining whether exporting LNG is in the public interest.
Michalek's study featured in Science: Electric vehicle range, emissions worse in extreme weather regions
Researchers have found that electric vehicles have shorter range and more emissions in regions with extreme weather. Mechanical Engineering and Engineering and Public Policy Professor Jeremy Michalek and mechanical engineering graduate student Tugce Yuksel used data from Nissan Leaf drivers and weather reports to analyze the regional effect of air temperature on the range, energy consumption and emissions of electric vehicles. "We found that average electric vehicle range in some regions can drop from a rated 75 miles to just 45 miles on the hottest or coldest days of the year," Yuksel said. According to the study, electric vehicles consume more energy in extreme weather for two primary reasons: heating or cooling the passenger cabin drains energy from the battery, and batteries also are less efficient when cold.

Min asks,"Should we be concerned that more efficient lights increase our furnace consumption?"
Some people could be concerned that replacing incandescent bulbs with more efficient ones would lead to more consumption from the furnace or boiler to heat the rooms during cold weather. This would be because incandescent light lights release a lot of the energy they consume as heat: this is called a "heat replacement effect”. EPP postdoctoral fellow Jihoon Min, professor Inês Azevedo, and Pekka Hakkarainen, vice president of Lutron Electronics, have estimated this effect for different regions of the country, and find that in most cases, this effect is not strong enough to offset the whole energy or carbon savings one gets from using more efficient lights. Indeed, they conclude that in almost all regions in the U.S., installing CFLs or LEDs will still make you save energy, carbon, and money even after his heat replacement effect is taken into account. http://tinyurl.com/muv639h

Tarr compares Westinghouse and Marcellus
EPP professor Joel Tarr wrote an article for New America on the Pittsburgh region’s historical identification with energy resources and environmental degradation and what that means for the future. Tarr, the Richard S. Caliguiri University Professor of History and Policy, wrote, "Does the history of energy development in the state have any implications for the present natural gas boom? I believe that there are a number of analogies between then and now that are worth exploring. The echo between past and present shows that concerns about the environmental impacts of natural gas development today could have been anticipated by looking at Pittsburgh’s history." Learning from Pittsburgh’s Energy History from Westinghouse to Marcellus."
