Description
Geology and its tangential studies, collectively known and referred to in this thesis as geosciences, have been paramount to the transformation and advancement of society, fundamentally changing the way we view, interact and live with the surrounding natural and built environment. It is important to recognize the value and importance of this interdisciplinary scientific field while reconciling its ties to imperial and colonizing extractive systems which have led to harmful and invasive endeavors. This intersection among geosciences, (environmental) justice studies, and decolonization is intended to promote inclusive pedagogical models through just and equitable methodologies and frameworks as to prevent further injustices and promote recognition and healing of old wounds. By utilizing decolonial frameworks and highlighting the voices of peoples from colonized and exploited landscapes, this annotated syllabus tackles the issues previously described while proposing solutions involving place-based education and the recentering of land within geoscience pedagogical models.

Description
This dissertation explores the functional purpose of imagination as it is enacted in the context of shaping large transitions in sociotechnical systems. Large sociotechnical systems undergoing profound transitions embody instantiations where societies experience profound changes in the ‘rules of the game’ that underpin the conduct of daily life. The forms of imagination that guide these transformations, known in the political theory literature as ‘imaginaries,’ play a profound yet undertheorized role in transition of sociotechnical systems from one configuration to another. Expanding on this relationship, the study draws on three case studies of energy systems change in the United States during 20th and 21st century. Each case study explores unique element of how actors at a variety of levels – transnational governance, regional electrification, and in-home energy marketing – define and the possibilities for ideal human and technological action and interaction through a transition. These actors defining the parameters of a new form of systems operation and configuration are as equally focused on defining how these new configurations shape fundamental ideas that underpin American democratic sensibility. Moreover, in the process of articulating a new configuration of energy and society – be that in terms of managing global resource flows or the automation of energy use in a residential home – questions of what makes an ideal member of a society are interlinked with new contractual relationships between energy producers and energy users. Transitions research could and should pay greater attention to the normative commitments emergent systems actors – as it is in these commitments we can chart pathways to redefine the parameters that underpin emergent transitions.

Description
Mexico City has an ongoing air pollution issue that negatively affects its citizens and surroundings with current structural disconnections preventing the city from improving its overall air quality. Thematic methodological analysis reveals current obstacles and barriers, as well as variables contributing to this persistent problem. A historical background reveals current programs and policies implemented to improve Mexico’s City air quality. Mexico City’s current systems, infrastructure, and policies are inadequate and ineffective. There is a lack of appropriate regulation on other modes of transportation, and the current government system fails to identify how the class disparity in the city and lack of adequate education are contributing to this ongoing problem. Education and adequate public awareness can potentially aid the fight against air pollution in the Metropolitan City.

Description
Is nuclear power sustainable when compared to other energy sources? A truly sustainable energy source provides an environmental benefit, minimizes costs to consumers both socially and economically, and continues to do so in both the short and the long term. Taking the zero-carbon nature of nuclear generation as its net environmental benefit, this paper the evaluates the economic and social costs of nuclear power to determine if nuclear power's reputation as "unsustainable" is warranted. The sustainability of nuclear power is evaluated in two main categories. The first part focuses on the economics of nuclear power. There are many preconceived notions regarding nuclear power and its associated industry. This section addresses those notions to determine their validity given recent data. The prevalent types of nuclear plants across the U.S., the economics of the stages of nuclear energy production, and its competitiveness relative to other energy sources are addressed, culminating in an evaluation of its modern economic attractiveness as well as its future economic viability. A sustainability assessment would not be complete without addressing the social costs of an energy source, as a sustainable source must be both economically and socially viable. If it can be established that nuclear power can provide energy at lower rates and at a lower cost in terms of externalities, then it would be considered truly sustainable. To investigate those externalities, the second part of the analysis focuses on the human costs associated with the various stages of nuclear energy production. Those costs are then compared to those of alternatives sources of power, and selected case studies are examined to illustrate the ultimate risks associated with nuclear power operations. By quantifying these aspects and comparing the results to alternatives in the field, a better understanding of nuclear energy technology and its potential is achieved. The reader can then ascertain whether nuclear power's reputation as being "unsustainable" is, or is not, a reputation it deserves.

Description
China's rapid growth was fueled by an unsustainable method: trade environment for GDP. Air pollution has reached dangerous levels and has taken a serious toll on China's economic progress. The World Bank estimates that in 2013, China lost about 10% of its GDP to pollution. As the cost of burning fossil fuels and public dismay continue to mount, the government is taking steps to reduce carbon emissions and appease the people. The rapidly growing nuclear energy program is one of the energy solutions that China is using to addressing carbon emissions. While China has built a respectable amount of renewable energy capacity (such as wind and solar), much of that capacity is not connected to the power grid. Nuclear energy on the other hand, provides a low-emission alternative that operates independently of weather and sunlight. However, the accelerated pace of reactor construction in recent years presents challenges for the safe operation of nuclear energy in China. It is in China's (and the world's) best interest that a repeat of the Fukushima accident does not occur. In the wake of the Fukushima nuclear accident, public support for nuclear energy in China took a serious hit. A major domestic nuclear accident would be detrimental to the development of nuclear energy in China and diminish the government's reliability in the eyes of the people. This paper will outline those risk factors such as regulatory efforts, legal framework, technological issues, spent fuel disposal, and public perception and provide suggestions to decrease the risk of a major nuclear accident.

Description
This paper offers a radical critique of consumer capitalism and consumer activism through advertisements from Industrial Food Systems. I examine advertisements from Monsanto, Industrial Beef Farmers, and Waste Management in order to critique the rhetoric that these companies use and reveal the environmental destruction they are attempting to obscure through the strategic use of language and symbols. I argue that a deeper anti-capitalist analysis of Industrial Food Systems is necessary to subvert consumer activism and greenwashing tactics and to curb environmental destruction.

Description
This paper seeks to analyze the relationship between energy subsidies on fossil fuels by countries and corresponding energy consumption, specifically electricity, by its citizens and occupants. The purpose of this was to determine whether pre-tax subsidies and post-tax subsidies have an effect on that consumption. This paper will discuss the prospect of accounting for post-tax subsidies as a method to curb rampant energy consumption throughout the world, with the focus being on residential electricity use. The two case studies, the Netherlands and Saudi Arabia, will illustrate the consumption patterns in relatively similar economic societies with different subsidy policies. Saudi Arabia will be a high pre-tax subsidy example while the Netherlands will be shown to account for some of the post-tax subsidies through an externality tax system. At the end of this analysis, this paper will show that the heavy subsidization of electricity production is strongly correlated to residential electricity consumption at levels that many officials would deem unsustainable, and that as such, subsidy reform is both beneficial and necessary.

Description
The mainstream American environmental movement has a reputation for being ethnically homogenous (i.e., white), especially within the field of conservation. Low minority involvement has been noted and discussed in the conservation literature and within environmental organizations, but these discussions aren't always informed by the explicit social justice concerns critical to understanding the complex intersection of environmental and social issues. Communities of color have expressed concern for environmental and conservation issues, but often frame those issues in a different way than is common in mainstream conservation science, a framing that we can appreciate through a deeper analysis of the values and goals of the environmental justice (EJ) movement. A more thorough inclusion of EJ principles could be an effective method to increase ethnic diversity in the field of conservation, particularly within higher education conservation programs like the Conservation Biology and Ecology (CBE) concentration at Arizona State University. This thesis frames the broader challenge of diversity in conservation, the history and current state of the conservation movement, and the history of the environmental justice movement via a literature review. I then evaluate the university's CBE program on the basis of its diversity through an analysis of demographic data on undergraduate ethnicity from the School of Life Sciences. I conclude with a series of recommendations for enhancing the diversity of ASU's CBE program moving forward.

Description
The purpose of this research is to study the effect of angle of acceptance and mechanical control system noise on the power available to a two-axis solar concentrating photovoltaic (CPV) system. The efficiency of a solar CPV system is greatly dependent on the accuracy of the tracking system because a strong focal point is needed to concentrate incident solar irradiation on the small, high efficiency cells. The objective of this study was to evaluate and quantify tracking accuracy for a performance model which would apply to similar two-axis systems. An analysis comparing CPV to traditional solar photovoltaics from an economic standpoint was conducted as well to evaluate the viability of emerging CPV technology. The research was performed using two calibrated solar radiation sensors mounted on the plane of the tracking system, normal to the sun. One sensor is held at a constant, normal angle (0 degrees) and the other is varied by a known interior angle in the range of 0 degrees to 10 degrees. This was to study the magnitude of the decrease in in irradiance as the angle deviation increases. The results show that, as the interior angle increases, the solar irradiance and thus available power available on the focal point will decrease roughly at a parabolic rate, with a sharp cutoff point at angles greater than 5 degrees. These findings have a significant impact on CPV system tracking mechanisms, which require high precision tracking in order to perform as intended.

Description
This study aims to teach the reader about the process of making a building more energy efficient at ASU. In this study the importance of energy efficiency in buildings will be discussed as well as how building efficiency is important for the three tiers of sustainability. The case of energy efficiency in the environment, economy, and society will be outlined with the intent of creating urgency for the implementation of energy efficiency. Environment, economy, and society, the three tiers of sustainability fit the model of energy efficiency because efficient energy is a principle of sustainability. Efficient energy can fill the gap between our energy system at present and the energy system of the future. This document outlines the steps that ASU goes through when there is an energy upgrade to a building on campus. It also includes a mock audit of the Psychology North building at ASU. This mock audit serves as an example to justify how the steps outlined in this document can be used to initiate an energy retrofit. A person who reads this document will be able to understand the energy retrofit process. The main argument is that there is room for student inclusion in this process, by giving students the knowledge on how to initiate an energy retrofit they have the tools to be included. Practicing building efficiency on campus will help ASU to succeed in accomplishing numbers two and four of their sustainability goals: "1) Carbon Neutrality, 2) Zero Solid/Water Waste, 3) Active Engagement, and 4) Principled Practice" (ASU, 2011).
