The United States is a driving force of the global economy and a major innovator in the technology sector. For decades the world has looked to The United States as a leader of great technological advancements with the strong economy to allow investors a chance make these technologies a reality. So why is it now that we lag behind other countries when it comes to making our technology energy efficient? Sure we’ve been steadily growing our production of renewable resources with wind and solar energy, bet we are still behind in the second largest source of pollution, transportation. According to …

When Addressing Climate Change, Don’T Forget Animal Agriculture, Aaron Matzke

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

As COP 21 closes in Paris, global animal agriculture is a topic that has eluded the international media. Animal agriculture is responsible for more global greenhouse gas emissions than transportation according to the U.N.’s Food and Agriculture Organization. With global population and prosperity rising, the global meat supply is expected to nearly double by 2050. This increase in production will only be achieved if significant steps are taken to promote sustainability through existing techniques globally, and to regulate air contamination in industrial feedlots in the United States. Alternative meat production methods, which have seen considerable investment recently, could supplement animal …

Energy Subsidies And The Future Of Power, Christian Jewett

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The modern political climate has grown rife with talk concerning the use of fossil fuels as an energy source and how this may impact our planet for generations to come. The Left and the Right seem to be at odds over whether or not climate change is actually occurring, or who is causing it. Additionally, the energy industry likes to tout their “low-cost” energy sources as a boon to the global economy as well as a benefit to the consumer at large. However, are coal, oil, and natural gas truly the “cheapest” sources of energy? Whether or not one believes …

Making Walkable Communities, Katie Zuehlke

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

There is no doubt that global warming is happening. With all the rage about climate change and global warming people should be doing more about it than just reading about it in the news. We should be making efforts towards making changes on a local level. This in turn could grow to a national level with more and more people participating in the movement and actually make global changes, instead of just talking about it. When the scale of participants grows the scale of the changes made will grow as well and this will be the beginning of the changes …

Incentives Critical To Full Wind Power Potential In Nebraska, Michael Neale

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

On August 3rd, President Obama and the EPA announced the Clean Power Plan (CPP) with the goal of cutting 32% of carbon emissions nationwide by 2030. The plan institutes carbon reduction requirements for all states based on their current sources of energy, for Nebraska the goal is 40%. The next day, Governor Ricketts and his Attorney General announced they would be fighting the mandate in court; stating the plan is unlawful federal government overreach, while expressing concerns the reduction are infeasible in the timeframe given and will drive up electricity costs. Governor Ricketts misses the point on this. Reducing carbon …

The Clean Power Plan Needs To Be A Law, Mitchell Frischmeyer

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The Clean Power Plan (CPP) is a long overdue policy which is necessary to direct national investment in emerging markets and create an intelligent energy infrastructure that strives to operate at max efficiency. To this point, the US has developed using inefficient and dirty fuels, a method which allowed for cheap and reliable energy generation, but is largely responsible for the change in global climate. If we expect to prevent climate change, our energy infrastructure must be reformed. Countries like Denmark have led the way in energy reform by creating policies set to reach 100% renewable generation by 2050 (8). …

Effects Of Wind Turbine Noise On Male Greater Prairie-Chicken Vocalizations And Chorus, Cara E. Whalen

School of Natural Resources: Dissertations, Theses, and Student Research

Wind energy facilities are constructed without full knowledge of their effects on birds, and the noise generated by wind turbines is a particular concern. I investigated the effects of wind turbine noise on male Greater Prairie-Chicken (Tympanuchus cupido pinnatus) vocalizations and chorus near Ainsworth, NE, USA in 2013 and 2014. I studied 14 leks located in the area surrounding a 36-turbine wind energy facility. I used two main approaches in this study. First, I recorded Greater Prairie-Chicken boom, cackle, whine, and whoop vocalizations at each of the study leks and measured the duration, sound pressure level, peak frequency, …

Seismic Surveys And Marine Turtles: An Underestimated Global Threat?, Sarah E. Nelms, Wendy Dow Piniak, Caroline R. Weir, Brendan J. Godley

Environmental Studies Faculty Publications

Seismic surveys are widely used in marine geophysical oil and gas exploration, employing airguns to produce sound-waves capable of penetrating the sea floor. In recent years, concerns have been raised over the biological impacts of this activity, particularly for marine mammals. While exploration occurs in the waters of at least fifty countries where marine turtles are present, the degree of threat posed by seismic surveys is almost entirely unknown. To investigate this issue, a mixed-methods approach involving a systematic review, policy comparison and stakeholder analysis was employed and recommendations for future research were identified. This study found that turtles have …

Analyzing Major Challenges Of Wind And Solar Variability In Power Systems, Falko Ueckerdt, Robert Brecha, Gunnar Luderer

Physics Faculty Publications

Ambitious policy targets together with current and projected high growth rates indicate that future power systems will likely show substantially increased generation from renewable energy sources. A large share will come from the variable renewable energy (VRE) sources wind and solar photovoltaics (PV); however, integrating wind and solar causes challenges for existing power systems. In this paper we analyze three major integration challenges related to the structural matching of demand with the supply of wind and solar power: low capacity credit, reduced utilization of dispatchable plants, and over-produced generation. Based on residual load duration curves we define corresponding challenge variables …

Biochemical, Physiological, And Anatomical Insights Into Aphid-Bioenergy Switchgrass Interactions, Travis J. Prochaska

Department of Entomology: Dissertations, Theses, and Student Research

Switchgrass, Panicum virgatum L., a perennial, warm-season grass native to North America, is a candidate for development as a bioenergy crop. Previously, warm-season grasses were considered to be relatively pest free in their native habitats. However, recent studies using the hemipteran family Aphididae have shown phloem-feeding insects can lead to significant injury in switchgrass. The objectives of this research were to: 1) gain physiological, biochemical, and anatomical insights into insect-bioenergy switchgrass interactions to determine potential insect resistance mechanisms among susceptible and resistant switchgrass genotypes; and 2) to generate and evaluate diverse segregating populations of switchgrass, both resistant and susceptible, to …

Innovations in Managing Western Water: New Approaches for Balancing Environmental, Social and Economic Outcomes (Martz Summer Conference, June 11-12)

Many aspects of western water allocation and management are the product of independent and uncoordinated actions, several occurring a century or more ago. However, in this modern era of water scarcity, it is increasingly acknowledged that more coordinated and deliberate decision-making is necessary for effectively balancing environmental, social, and economic objectives. In recent years, a variety of forums, processes, and tools have emerged to better manage the connections between regions, sectors, and publics linked by shared water systems. In this event, we explore the cutting edge efforts, the latest points of contention, and the opportunities for further progress.

Air Pollution Differences Between Nations With Different Economic Profiles, Alliyah Sato

Student Scholar Symposium Abstracts and Posters

The economics of a country plays an important role in determining what that country considers as its priorities. A developed country, such as the U.S., is powerful economically. As a result, it has the resources and tools to focus on other aspects of the nation. One of these features is the environment. Countries undergoing urbanization and industrial development processes, such as China, are emitting large amounts of pollutants into the atmosphere. Although it has adverse health and ecological effects, China has shown very little reduction of its emissions from 2000-2014. It relies heavily on coal burning as a source of …

Boom Or Bust? Mapping Out The Known Unknowns Of Global Shale Gas Production Potential, Jérôme Hilaire, Nico Bauer, Robert J. Brecha

Physics Faculty Publications

To assess the global production costs of shale gas, we combine global top-down data with detailed bottom-up information. Studies solely based on top-down approaches do not adequately account for the heterogeneity of shale gas deposits and hence, are unlikely to appropriately capture the extraction costs of shale gas. We design and provide an expedient bottom-up method based on publicly available US data to compute the levelized costs of shale gas extraction. Our results indicate the existence of economically attractive areas but also reveal a dramatic cost increase as lower-quality reservoirs are exploited. At the global level, our best estimate suggests …

Cost-Availability Curves For Hierarchical Implementation Of Residential Energy-Efficiency Measures, Roman Villoria-Siegert, Philip Brodrick, Kevin P. Hallinan, Robert J. Brecha

Physics Faculty Publications

Historical residential electricity data and natural gas consumption data were collected for, respectively, 1,200 and 178 residences in a small town in the USA. These data were merged with local building and weather databases, and energy consumption models were developed for each residence, revealing substantial variation in heating and cooling intensity. After estimating approximate physical building characteristics, energy profiles for each residence were calculated, and savings from adoption of the most cost-effective energy-efficiency measures for each residence were estimated. Effectively, we wish to leverage commonly available data sets to infer characteristics of building envelopes and equipment, without the need for …

Vietnam’s economy has grown extensively over the past twenty years; however, 68% of the population still lives in rural areas. The government of Vietnam has taken huge steps in the growth of rural infrastructure, specifically electricity. According to the World Bank 95% of the rural population had access to electricity as of 2010. This paper discusses how this electricity is being used in rural areas and whether the uses are aiding in the national growth of Vietnam. Productive uses, those which result in production of income, or value, are compared with solely economic uses. A case study comprised of surveys, …

Three Essays On Biofuels, Drought, Livestock, And The Environment, Sunil P. Dhoubhadel

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This dissertation consists of three essays. The first essay examines the impact of the 2012 drought and the biofuels mandate on the U.S. grain and livestock markets. A stochastic equilibrium displacement model is used to analyze the impact on eight commodity markets viz. beef, pork, poultry, corn, distillers’ grain (DG), soybean, soymeal, and ethanol. Among the eight markets, corn and beef are found to be the most vulnerable to drought. The use of Renewable Identification Number (RIN) credits as an instrument to mitigate the impact of drought has limited effectiveness. A mandate waiver of about 23% is required to fully …

Taming The Teesta: Exploring The Holistic Effects Of Hydroelectric Dam Development On The Teesta River Through Documentary Film, Taylor Graham

Independent Study Project (ISP) Collection

Since time immemorial, the Lepcha people have called the Himalayan region that makes up the modern state of Sikkim their home and have held sacred the rivers, mountains, and forests that make up the biologically diverse region. Over the past two decades, India’s rapid development has generated a powerful thirst for electricity, and the country has increasingly looked to the cold, powerful rivers thundering from the Himalayas to supply that desired power. Hydroelectric projects have been proposed and implemented throughout the Himalayan region. Nowhere, however, are the dams as numerous or their effects as acutely felt as in India’s northwestern …

The Adequacy Of Programs In Nsw In Supporting Vulnerable Households To Transition To Renewable Energy, Madison Dell

Independent Study Project (ISP) Collection

Rising electricity prices in Australia have caused low-income households to take drastic measures to reduce their energy consumption, cutting back on essential needs like food and heating. At the same time, prices for renewable energies like solar PV are decreasing, making renewable energy a more viable option for low-income households than grid electricity. In support of increasing the nation’s supply of renewable energy, the New South Wales government is funding the Zero Net Energy Town (Z-NET) project. The Z-NET project is a new initiative to create Australia’s first town that supplies all of its energy through renewable energy sources, using …

Algal Biomass As A Binding Agent For The Densification Of Miscanthus, Sunil Thapa, Daniel Johnson, Peter Liu, Thomas Canam

Faculty Research & Creative Activity

Purpose: Lignocellulosic biomass has been regarded as an important future energy source due to its excessive availability; however, the wide application of this material for many applications is restricted by the high costs associated with densification, transportation, thermo-chemical pretreatment and conversion. In order to increase the density of lignocellulosic biomass, it is typically compressed into pellets or briquettes. This frequently requires the addition of additives, which may negatively impact the economics of the process. Environmentally-friendly binding agents that can be obtained inexpensively are therefore desirable. This study examines the change in physicochemical properties of densified Miscanthus straw where algae were …
