Analysis of the discourse, frames, and content surrounding unconventional energy policy and development in the Western United States was conducted using three case studies. The results contribute to an understanding of energy-related risk perceptions in social and historical contexts.
Discourses contained in newspapers and public comments to the Bureau of Land Management presented arguments on the basis of risks to the environment; climate; human health and safety; jobs and economic prosperity; property rights; and local governments. Governments were seen as risks when they were perceived to allow misuse …
Design Guidelines And Strategies For Thermal Solar Management Of Fenestration In The Desert Climate, David Mccredo
Design Guidelines And Strategies For Thermal Solar Management Of Fenestration In The Desert Climate, David Mccredo
UNLV Theses, Dissertations, Professional Papers, and Capstones
This research evaluates the effects of varying thermal properties of windows in
residential energy use for the moderate altitude and 36'N latitude climate of southern
Nevada, which has a distinct cooling season. A selection of windows across different
shading conditions and total window areas were studied using BEopt energy simulation.
Findings demonstrate that for the specific climate, latitude, and altitude of Las Vegas,
Nevada, the most expensive “high performance” windows are not always the best
option in terms of total site energy use, and can be outperformed by properly shaded
less advanced windows. Under certain conditions, shading was found to …

An Abstract of the Thesis by
Ahlam Alghamdi
The main objective of this study is to synthesize nanostructured cobalt oxide decorated on polypyrrole using a facile method for energy applications. For this, polypyrrole was first synthesized using a chemical polymerization method. In the second step, a varying amount of cobalt oxide was decorated on polypyrrole using a hydrothermal process. The synthesized materials were structurally and electrochemically characterized. It was observed that the electrochemical properties of the composites depend on their composition. The …
Thermoelectrics And Thermoelectric Devices, Benjamin T. Erck
Thermoelectrics And Thermoelectric Devices, Benjamin T. Erck
Senior Theses
The field of thermoelectrics has many applications, and more are found in everyday systems. From its current studies, it is apparent that improving the figure of merit zT (which defines a good thermoelectric material) is important in the effectiveness of power generation. Another important part of thermoelectrics is the duality of these devices. They can both move heat and generate power, depending on their role in the system. In this thesis research, a process was made to test these thermoelectric relationships for a few Peltier devices in order to understand their efficiencies and what systems they can be applied to.

Lithium And The Foreseeable Future, Paolo Vargas
Mechanical Engineering Undergraduate Honors Theses
This paper aims to clarify the uncertainties regarding worldwide lithium resource availability in the years to come. Previous studies made on the subject are presented with some ambiguity and this work intends to fill the gaps. The information and data presented throughout this script with respect to global lithium resources and reserves are mostly based on data released by the United States Geological Survey (USGS). Lithium resource availability in the future is a point of paramount significance primarily for the automotive, portable electronics, and the power generation industry. Since, a change of supply would ultimately affect the price of lithium, …
Energy Calculations And Wave Equations, Ellen R. Hunter
Energy Calculations And Wave Equations, Ellen R. Hunter
MSU Graduate Theses
The focus of this thesis is to show how methods of Fourier analysis, in particular Parseval’s equality, can be used to provide explicit energy calculations for solutions of wave equations in one dimension. These calculations are discussed for simple examples and then extended to fit the general wave equation with Robin boundary conditions. Ideas from Sobolev space theory are used to provide justification of the method.

Single-Stage, Venturi-Driven Desalination System, Brandon Proetto
Mechanical & Aerospace Engineering Theses & Dissertations
Water demand is increasing at a rapid pace due to population increase, industrial expansion, and agricultural development. The use of desalination technology to meet the high water demands has increased global online desalination capacity from 47 million m^3/d in 2007 to 92.5 million m^3/d as of June 2017 [49]. Membrane and thermal processes are the two mainstream desalination categories used worldwide for desalination plants. Reverse Osmosis (RO) is the most widely used membrane process and it has become the dominant technology for building desalination plants over recent decades. Thermal distillation, however, has become less and less competitive due to its …
Functionalized Nanoporous Carbon Scaffolds For Hydrogen Storage Applications, Christopher Carr
Functionalized Nanoporous Carbon Scaffolds For Hydrogen Storage Applications, Christopher Carr
Dissertations
Recent efforts have demonstrated confinement in porous scaffolds at the nanoscale can alter the hydrogen sorption properties of metal hydrides, though not to an extent feasible for use in onboard hydrogen storage applications, proposing the need for a method allowing further modifications. The work presented here explores how the functionalization of nanoporous carbon scaffold surfaces with heteroatoms can modify the hydrogen sorption properties of confined metal hydrides in relation to non-functionalized scaffolds (FS). Investigations of nanoconfined LiBH4and NaAlH4indicate functionalizing the carbon scaffold surface with nitrogen can shift the activation energy of hydrogen desorption in excess of …

Rental Property Energy Efficiency In San Luis Obispo, Zachary Earl Shockley
Physics
In the modern era, many people choose to rent homes instead of purchasing a home. College towns have an even more disproportionate number of renters when compared to other cities. The majority of rental properties are much less energy efficient than their owner-occupied counterparts. This project analyzes the energy efficiency issues of rental properties in San Luis Obispo and examines potential ways to remedy these issues. In order to analyze these issues, the guiding principles of building science are first discussed, followed by case studies of rental properties in San Luis Obispo. These case studies examine multiple rental properties and …

Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman
Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman
Pitzer Senior Theses
State energy plans are created at the request of a sitting governor or State Legislature in order to provide guidance set goals for the state’s energy sector. These plans will be critical indicators of energy trends such as the future market share of coal, natural gas, and renewables. If the future of energy in the United States is to be remotely sustainable, low-carbon policies must headline state plans. The strength of a state’s energy plan in terms of sustainability is directly related to that state’s willingness to prioritize and commit to incorporating energy sources that produce negligible carbon emissions. Questions …
