Impact On Merchant Refiners And Blenders From Changing The Rfs Point Of Obligation, 2017 Iowa State University
Impact On Merchant Refiners And Blenders From Changing The Rfs Point Of Obligation, Bruce A. Babcock, Gabriel E. Lade, Sébastien Pouliot
The Environmental Protection Agency has proposed to deny a request to move the point of obligation under the Renewable Fuel Standard (RFS) from oil refiners to fuel blenders. Supporters of the request argue that those refiners who do not have the fuel blending capabilities of large, integrated oil companies are in danger of going out of business due to their need to buy RINs (Renewable Identification Numbers) to show compliance with the RFS. We demonstrate that this claim is false and that moving the point of obligation would have no impact on refiner profits. The key point that is neglected ...
Estimating Willingness To Pay For E85 In The United States, 2017 Iowa State University
Estimating Willingness To Pay For E85 In The United States, Kenneth Liao, Sébastien Pouliot, Bruce A. Babcock
Meeting US ethanol blending mandates proposed by the Environmental Protection Agency will require a substantial number of motorists with flex-fuel vehicles to switch from low ethanol-gasoline blends to high ethanol-gasoline blends. The lower the willingness to pay for high-ethanol blends, the greater the cost of complying with the proposed mandates. Existing estimates of the willingness to pay for high-ethanol blends use data from Brazil (where consumers have knowledge of and experience with high-ethanol blends), data generated when retail prices greatly favored low-ethanol blends, or stated data collected from mail and online surveys. To obtain more accurate estimates of US willingness ...
Greenhouse Gas Impacts Of Ethanol From Iowa Corn: Life Cycle Analysis Versus System-Wide Accounting, 2017 Iowa State University
Greenhouse Gas Impacts Of Ethanol From Iowa Corn: Life Cycle Analysis Versus System-Wide Accounting, Hongli Feng, Ofir D. Rubin, Bruce A. Babcock
Life cycle analysis (LCA) is the standard approach used to evaluate the greenhouse gas (GHG) benefits of biofuels. However, it is increasingly recognized that LCA results do not account for some impacts—including land use changes—that have important implications on GHGs. Thus, an alternative accounting system that goes beyond LCA is needed. In this paper, we contribute to the literature by laying out the basics of a system-wide accounting (SWA) method that takes into account all potential changes in GHGs resulting from biofuel expansion. We applied both LCA and SWA to assess the GHG impacts of ethanol based on ...

Is Corn Ethanol A Low-Carbon Fuel?, Bruce A. Babcock, Ofir Rubin, Hongli Feng
Reports of disappearing glaciers, shrinking arctic ice, rising sea levels, stronger hurricanes, and unprecedented European heat waves combined with an inexorable buildup in atmospheric carbon dioxide levels is increasing pressure on governments to respond with new greenhouse gas initiatives. California and other states are providing policy leadership in the United States
Impacts Of Ethanol On Planted Acreage In Market Equilibrium, 2017 Iowa State University
Impacts Of Ethanol On Planted Acreage In Market Equilibrium, Hongli Feng, Bruce A. Babcock
Land use impacts of biofuel expansion have attracted a tremendous amount of attention because of the implications for the climate, the environment, and the food supply. To examine these impacts, we set up an economic framework that links input use and land allocation decisions with ethanol and agricultural commodity markets. Crops can be substitutes or complements in supply depending on the relative magnitude of three effects of crop prices: total cropland effect, land share effect, and input use effect. We show that with unregulated free markets, total cropland area increases with corn prices whether crops are substitutes or complements in ...
Fossil Fuel Asset Risk Analysis: Clark University Endowment, 2017 Clark University
Fossil Fuel Asset Risk Analysis: Clark University Endowment, Travis A. Dodge, B. Maiwand Akbari
The environmental and social risks of climate change are well known and perhaps inevitable. The economic and financial risks are less so. The many financial risks associated with climate change embedded in endowment portfolio fossil fuel holdings are leading many institutional stakeholders to enter into dialogue and take action. Divestment is emerging as an effective strategy for limiting portfolio exposure and tackling climate change itself.
Our team’s goals were to assess whether the Clark University endowment portfolio faces any of these risks and evaluate the impacts on asset values. Our findings show that the Clark endowment does face these ...
Economic Evaluation Of Coastal Land Loss In Louisiana, 2017 Louisiana State University
Economic Evaluation Of Coastal Land Loss In Louisiana, Stephen R. Barnes, Craig Bond, Nicholas Burger, Kate Anania, Aaron Strong, Sarah Weilant, Stephanie Virgets
Journal of Ocean and Coastal Economics
Louisiana has lost approximately 1,880 square miles of land over the past eighty years. Projections suggest that in a future without action, the next fifty years could result in the loss of 1,750 additional square miles of land area. As land loss continues, a large portion of the natural and man-made capital stocks of coastal Louisiana will be at greater risk of damage, either from land loss or from the associated increase in storm damage. We estimate the replacement cost of capital stock directly at risk from land loss ranges from approximately $2.1 billion to $3.5 ...

Solar PV generation has become an integral part of the renewable energy industry. With state-level, renewable portfolio standards in place, solar power demand has substantially increased and become a competitive and economically viable energy solution throughout the world. Hawaii has one of the most aggressive renewable portfolio standards with a goal of 100 percent renewable generation by 2045. However, there are challenges that are preventing the growth of the solar PV market in Hawaii including equal accessibility to solar power and solar power overloading causing grid instability. With Hawaii’s high annual solar radiation, PV generation could play a significant ...
California Public Electric Vehicle Charging Stations’ Accessibility To Amenities: A Gis Network Analysis Approach, 2017 University of San Francisco
California Public Electric Vehicle Charging Stations’ Accessibility To Amenities: A Gis Network Analysis Approach, Jeremy Yun Li Chen
Master's Projects and Capstones
In California, the number of electric vehicles (EVs) on the roads has been increasing over the past several years. As EVs continue to grow, additional electric vehicle charging stations (EVCSs) will be needed for EV drivers to utilize. However, before implementing EVCSs in the public, there are various criteria that need to be considered. One of these criteria is public EVCSs’ accessibility to amenities. When people are charging their EVs that require a significant amount of waiting time, having amenities nearby will provide them with the option to spend their time efficiently on worthwhile activities. To understand the accessibility of ...
Examining The Effects Of Policy Interventions On Increasing Electric Vehicle Adoption In California, 2017 University of San Francisco
Examining The Effects Of Policy Interventions On Increasing Electric Vehicle Adoption In California, Ethan G. Mcdermott
Master's Projects and Capstones
Any significant effort to reduce global emissions of greenhouse gasses must address the growing concern of the transportation sector’s inability to meaningfully reduce its emissions contribution. A major shift in the primary fuel used in the sector away from petroleum-based fuel to electricity is one potential way the sector can lower its emissions and transition into a sustainable future. However, a number of barriers face the electric vehicle market, including competing against an already mature vehicle market, battling consumer preferences, and overcoming technical challenges. This paper examines several policy proposals to combat these barriers and examines the impact similar ...

Sub 2 Nm Particle Characterization In Systems With Aerosol Formation And Growth, 2017 Washington University in St. Louis
Sub 2 Nm Particle Characterization In Systems With Aerosol Formation And Growth, Yang Wang
Engineering and Applied Science Theses & Dissertations
Aerosol science and technology enable continual advances in material synthesis and atmospheric pollutant control. Among these advances, one important frontier is characterizing the initial stages of particle formation by real time measurement of particles below 2 nm in size. Sub 2 nm particles play important roles by acting as seeds for particle growth, ultimately determining the final properties of the generated particles. Tailoring nanoparticle properties requires a thorough understanding and precise control of the particle formation processes, which in turn requires characterizing nanoparticle formation from the initial stages. The knowledge on particle formation in early stages can also be applied ...
Wind Energy Conversion By Plant-Inspired Designs, 2017 Iowa State University
Wind Energy Conversion By Plant-Inspired Designs, Michael A. Mccloskey, Curtis L. Mosher, Eric R. Henderson
In 2008 the U.S. Department of Energy set a target of 20% wind energy by 2030. To date, induction-based turbines form the mainstay of this effort, but turbines are noisy, perceived as unattractive, a potential hazard to bats and birds, and their height hampers deployment in residential settings. Several groups have proposed that artificial plants containing piezoelectric elements may harvest wind energy sufficient to contribute to a carbon-neutral energy economy. Here we measured energy conversion by cottonwood-inspired piezoelectric leaves, and by a “vertical flapping stalk”—the most efficient piezo-leaf previously reported. We emulated cottonwood for its unusually ordered, periodic ...
Water-Energy Sector Collaboration In The United States: Benefits, Barriers, And Climate-Change Implications, Cassandra J. Osterhoudt
International Development, Community and Environment (IDCE)
The purpose of this report is to examine the impact of the water-energy nexus in the United States, and identify opportunities for increased collaboration between water and energy utilities. Through reviewing the regulatory history of both sectors, I explore how regulations on utilities align with the Porter Hypothesis, and the impacts the water-energy nexus will have moving forward, including under climate-change scenarios. The extent of collaboration between sectors has been relatively limited to states with progressive energy and water efficiency policies. This report identifies existing barriers and benefits to collaboration, and utilizes two case studies; California and Massachusetts. Results are ...
Pine Needle Pyrolysis: Bio-Waste Into Biofuel, 2017 Dominican University of California
Pine Needle Pyrolysis: Bio-Waste Into Biofuel, Alexandra Fuentes
Scholarly & Creative Works Conference 2017
This project explores the alternate uses of biomass. In particular, it focuses on pine needles as a source for biofuels. Pine needles are of interest because in certain Mountain communities they are collected and removed from residential properties. By removing the pine needles, communities create a “defensible space” to prevent wild fires from destroying homes. These needles are often placed in regional landfills. The South Tahoe Refuse and Recycling Services alone has more than 4,340 tons of pine needles dumped at their facility annually. This large amount of biomass can be a potential energy source.
The focus of this ...

Optimization And Performance Study Of Select Heating Ventilation And Air Conditioning Technologies For Commercial Buildings, 2017 University of South Florida
Optimization And Performance Study Of Select Heating Ventilation And Air Conditioning Technologies For Commercial Buildings, Rajeev Kamal
Graduate Theses and Dissertations
Buildings contribute a significant part to the electricity demand profile and peak demand for the electrical utilities. The addition of renewable energy generation adds additional variability and uncertainty to the power system. Demand side management in the buildings can help improve the demand profile for the utilities by shifting some of the demand from peak to off-peak times.
Heating, ventilation and air-conditioning contribute around 45% to the overall demand of a building. This research studies two strategies for reducing the peak as well as shifting some demand from peak to off-peak periods in commercial buildings:
1. Use of gas heat ...
