Stakeholder Participation And Influence At State Public Utility Commissions, Genevieve Theresa Kruse

Dissertations and Theses

Despite the international consensus that climate change is a problem, few substantive policies are being pushed forward at the national level to meet international greenhouse gas reduction commitments under the Paris Agreement. The most significant climate change policies are emerging at state public utility commissions (PUCs). While PUCs were traditionally structured to regulate utilities, state PUCs are now finding themselves at the hub for renewable energy, clean energy, and distributed energy policies. Despite the increase in renewable and clean energy policies at state PUCs, there is a noticeably small environmental and clean energy stakeholder presence at those PUC proceedings. A …

Intra-Hour Solar Forecasting Using Cloud Dynamics Features Extracted From Ground-Based Infrared Sky Images, Guillermo Terrén-Serrano

Electrical and Computer Engineering ETDs

Due to the increasing use of photovoltaic systems, power grids are vulnerable to the projection of shadows from moving clouds. An intra-hour solar forecast provides power grids with the capability of automatically controlling the dispatch of energy, reducing the additional cost for a guaranteed, reliable supply of energy (i.e., energy storage). This dissertation introduces a novel sky imager consisting of a long-wave radiometric infrared camera and a visible light camera with a fisheye lens. The imager is mounted on a solar tracker to maintain the Sun in the center of the images throughout the day, reducing the scattering effect produced …

Energy Literacy In Portugal: A System Map And Framework To Increase Energy Literacy Through The Renewable Energy Transition, Molly S. Fox

Independent Study Project (ISP) Collection

Western society lives with a great dependence and an almost simultaneous ignorance of energy consumption (van den Broek, 2019). The systemic landscape of energy knowledge and dissemination is more critical than ever as Portugal races to meet decarbonization goals. This paper fills a knowledge gap by updating the current social landscape of energy literacy in Portugal through a comprehensive system map and framework to increase energy literacy levels through the renewable energy transition. By conducting a semi-systematic literature review, meta-narratives and themes were identified and used to create theoretical concepts, a framework, and a system map. This research found that …

Design, Development, And Characterization Of Highly Efficient Colored Photovoltaic Module For Sustainable Buildings Applications, Mohammad Khairul Basher, Mohammad Nur-E-Alam, Momtazur Rahman, Steven Hinckley, Kamal Alameh

Research outputs 2022 to 2026

The building integrated photovoltaic (BIPV) system is one of the contributors which has enormous potential to reach the goal of net-zero energy buildings (NZEB) that significantly reduce the use of fossil fuels that contribute to global warming. However, the limitations of the visual and aesthetic appearance of current BIPV systems make this aspiration unlikely. This study investigates the limitations of the single-color-based PV modules that are dull in appearance and have low photo-conversion efficiency (PCE). In order to solve this issue, we designed, developed, and characterized micro-patterned-based multicolored photovoltaic (MPCPV) modules which are applicable to net-zero building and development. Our …

Why Capacity Market Prices Are Too High, Todd S. Aagaard, Andrew N. Kleit

Faculty Publications

The Federal Energy Regulatory Commission and regional transmission organizations have fixated on a concern that prices in electricity capacity markets are too low. In fact, however, capacity markets are significantly overpriced. The reason for this is that the administratively determined demand curves in capacity markets create conditions that procure far more electricity capacity than what is needed to meet reliability objectives. In particular, the operators of these markets systematically overestimate both the relevant peak demand for electricity and needed payments for generators to enter the market. The result is that consumer pay billions of dollars extra for excess capacity.

Application Of Machine Learning To Predict The Performance Of An Emipg Reactor Using Data From Numerical Simulations, Owen Sedej, Eric G. Mbonimpa, Trevor Sleight, Jeremy Slagley

Faculty Publications

Microwave-driven plasma gasification technology has the potential to produce clean energy from municipal and industrial solid wastes. It can generate temperatures above 2000 K (as high as 30,000 K) in a reactor, leading to complete combustion and reduction of toxic byproducts. Characterizing complex processes inside such a system is however challenging. In previous studies, simulations using computational fluid dynamics (CFD) produced reproducible results, but the simulations are tedious and involve assumptions. In this study, we propose machine-learning models that can be used in tandem with CFD, to accelerate high-fidelity fluid simulation, improve turbulence modeling, and enhance reduced-order models. A two-dimensional …

Geothermal Development In Kenya: Gender Based Socio-Cultural And Socio-Economic Implications, Faye N. Ricker

USF Tampa Graduate Theses and Dissertations

This dissertation is an ethnographic case study that analyzes the gendered socio-cultural and socio-economic implications for a community that was displaced in order to develop a geothermal energy system in Kenya. The implications are rendered particularly interesting because the displaced community is also one of the communities served by the geothermal power grid. The analysis employs a composite framework of Feminist Political Ecology and the Political Ecology of Climate Change Mitigation. This work explores gendered perceptions and control of energy, livelihood activities, place attachment, and the cultural/spiritual significance of geothermal energy.

Fiber-Based Electrical Energy Storage And Harvesting Devices For Wearable Electronics, Tareq Kareri

USF Tampa Graduate Theses and Dissertations

Over the past few years, smart textiles and wearable technologies have received tremendous attention due to their functionalities and characteristics, which could be used in a variety of ways in healthcare, sports/leisure, fashion, military, personal protective, and energy applications. These technologies depend on self-power systems, which require energy sources (e.g., batteries, supercapacitors, and solar cells) to power their projected functionalities in the future. Therefore, fabricating energy harvesting cells (i.e., solar cells) and energy storage cells (i.e., batteries and supercapacitors) in the form of fibers are promising solutions for powering wearable electronics due to their unique features such as flexibility and …

Theoretical Basis Of Dredging And Efficient Development Of High−Rank Coalbed Methane In China: A Case Study Of The Qinshui Basin, Zhu Qingzhong

Coal Geology & Exploration

China is rich in high-rank coalbed methane(CBM) resources, which accounts for more than 90% of the total production of CBM in China. The efficient development and utilization of high-rank coal and coalbed methane(CBM) resources is of great practical significance for ensuring national energy strategic security and helping to achieve the strategic goals of “carbon peak and carbon neutrality”. The coalbed methane industry in China is generally characterized by low exploration and development degree, poor adaptability of main technology, low rate of return on investment and small development scale. The large-scale and efficient development of coalbed methane is faced with great …
