The recent advent of shale gas in the U.S. has redefined the economics of ethylene manufacturing globally, causing a shift towards low-cost U.S. production due to natural gas feedstock, while reinforcing the industry's reliance on fossil fuels. At the same time, the global climate change crisis compels a transition to a low-carbon economy. These two influencing factors are complex, contested, and uncertain. This paper projects the United States' (U.S.) future ethylene supply in the context of two megatrends: the natural gas surge and global climate change. The analysis models the future U.S. supply of ethylene in 2050 based on plausible socio-economic scenarios in response to climate change mitigation and adaptation pathways as well as a range of natural gas feedstock prices. This Vector Error Correction Model explores the relationships between these variables. The results show that ethylene supply increased in nearly all modeled scenarios. A combination of lower population growth, lower consumption, and higher natural gas prices reduced ethylene supply by 2050. In most cases, forecasted CO2 emissions from ethylene production rose. This is the first study to project future ethylene supply to go beyond the price of feedstocks and include socio-economic variables relevant to climate change mitigation and adaptation.

A sociotechnical energy transition requires both a shift to new technologies and attention to social issues like political movements, policy and human behavior. This dissertation investigates social elements of the renewable energy transition occurring at different scales. The core research questions are: How are universities creating and responding to the shifting language of fossil fuel investments? How and for whom do behavioral interventions work? And finally, do in-home displays (IHDs) change behaviors and attitudes of millennial energy users? The three studies covered here occurred within higher education and reflect the importance of colleges and universities as dynamic players in energy transitions. These spaces encourage learning and organizational change on the inside while also pushing outward, challenging social norms. Using a coding approach and text analysis software, this research identifies common frames of language used by colleges and universities who have released formal statements rejecting or adopting divestment policies. This study provides a quantitative assessment of themes and an early overview of this dynamic movement. The second and third study describe the outcomes of a behavioral energy experiment with off-campus students at the University of Vermont testing real-time feedback and financial incentives on individuals' behavior. The second study analyzes the results of a survey conducted with participants in the experiment, investigating changes in attitudes and self-reported behaviors and correlations with actual energy usage. Applying Wilcoxon-signed rank tests and a repeated measures marginal model, showed a minimal effect from the behavioral interventions in survey responses. The results also raise questions about surveys as a reliable predictor for behavior-based outcomes. In the third study, interview data from participants sheds light on questions of how and for whom behavioral interventions work. A within-households split-incentive is discovered, describing one factor contributing to the limited effect of in-home displays on household energy usage. Other factors affecting household energy use are also discussed. This dissertation concludes with recommendations for utilities and policy makers.

In order to find politically feasible ways to reduce greenhouse gas emission emissions, governments must examine how policies affect a variety of stakeholders. The costs and benefits of low carbon technology options are unique and affect different market participants in different ways. In this thesis, we examine the cost effectiveness of carbon mitigation technologies and policies from the social perspective and from the perspective of consumers. In Chapter 2, we perform an engineering-economic analysis of hybridizing concentrating solar thermal power with fossil fuel. We examine the cost effectiveness of substituting the solar power for new coal or gas and find the cost of mitigation to be approximately ~$130/tCO2 to ~$300/tCO2. In Chapter 3, we quantify some externalized social costs and benefits of wind energy. We estimate the costs due to variability and transmission unique to wind to have an expected value of ~$20/MWh. In Chapter 4, we quantify the cost effectiveness of a renewable portfolio standard and a carbon price from the perspective of consumers in restructured markets. We find that both that the RPS can be more cost effective than a carbon price for consumers under certain circumstances: continued excess supply of capacity, retention of nuclear generators, and high natural gas prices. In Chapter 5, we examine the implications of lowering electricity sector CO2 emissions in PJM through a Low Carbon Capacity Standard (LCCS). We estimate that an LCCS would supply the same amount of energy (105,000 GWh) as the RPS’s in PJM and an additional ~10 GW of capacity. We find that the LCCS could be more cost effective for consumers than an RPS if it lowered capacity prices.

Electrification of low-income rural areas that have a limited connection or no access to electrical grids is one of the most demanding challenges in developing countries such as Peru. The international commitment to stop global warming and the reduction in the cost of renewable sources of energy have reduced the prices of fossil fuels in some cases. This has opened the way to the current research which proposes a hybrid energy system (HES) based on the use of renewable sources of energy. Therefore, a renewable electricity system (HRES) was set up at the village of Monte-Catache in the Cajamarca region, which is one of the poorest areas of Peru. Surveys and field studies were used to evaluate the socioeconomic characteristics, availability of renewable energy resources, and energy demand of this region. Potential energy sources were evaluated, and isolated photovoltaic systems with a battery bank were found to be the most appropriate according to the results obtained in the simulation with HOMER. This proposal constitutes an interesting contribution for future energy solutions in isolated and low-income rural areas. / Revisión por pares

This dissertation analyzes the case of organized climate change denial in the United States as a manifestation of the power of the policy planning and opinion shaping networks in the US. It uses a variety of power structure research techniques to put together a topographical study of a fossil fuels network sitting at the core of a wider conservative network which sits at the core of the policy planning and opinion shaping processes. The connections between the core fossil fuels network and wider conservative policy network are examined at length. Using climate change denial as the case allows for the study of how a distinct industry— fossil fuels—can organize a faction which can help set the ideological agenda of the wider corporate and conservative networks. A power elite theoretical approach outlined by Domhoff is used, and the conclusions that may be drawn from this case study support the usefulness of that approach. I also find that the case at hand illustrates how Domhoff’s model may be extended and augmented in light of the strategic and tactical innovations employed by those in the climate change denial faction. Although elites have often tried—with varying levels of success—to employ at least a veneer of populist support in formulating policy, climate change denial employs a new level of sophistication in then fossil fuels’ faction’s long-term strategic planning and investment. This faction’s ability to wrest ideological control of much of the tea party movement and bring that party's policy aims into lie with its own allowed for the addition of a powerful populist element to the climate change denial tactical repertoire. Similarly, new secrecy techniques go far beyond those used by elites in the past, reflecting a new set of needs on the part of the individuals and groups involved in the policy network and necessitating the augmentation of the existing network with specialized entities.
