Evaluating Barriers To And Impacts Of Rural Broadband Access, Javier Valentín-Sívico
Evaluating Barriers To And Impacts Of Rural Broadband Access, Javier Valentín-Sívico
Doctoral Dissertations
"The lack of adequate broadband infrastructure persists in many rural communities. Beyond funding, additional barriers persist, such as digital literacy and community-level self-efficacy. As a result, the first contribution articulates barriers at the organizational level. This work proposes a framework based on the Theory of Planned Behavior to highlight stakeholder dynamics that have constrained Regional Planning Commissions from advancing broadband infrastructure in rural areas. One approach to address these barriers is to provide stakeholders with analytical tools to evaluate the benefits and costs of various broadband options for their community since there is not a one-size-fits-all solution. To this end, …

State Level Trends In Renewable Energy Procurement Via Solar Installation Versus Green Electricity, Eric Michael Hanson
State Level Trends In Renewable Energy Procurement Via Solar Installation Versus Green Electricity, Eric Michael Hanson
Masters Theses
“In the past 5 years, consumer options for procuring renewable energy have increased, ranging from rooftop solar installation to utility green pricing to Community Choice Aggregation. These options vary in terms of costs and benefits to the consumer as well as grid integration implications. However, little is known regarding how the presence of a wide range of options for utility-scale renewable procurement affects demand for distributed residential solar installations. In theory, there are three possible relationships, (1) positive correlation, where utility-scale and distributed resources complement each other to increase overall production, (2) negative correlation, where utility-scale and distributed resources are …

Case one examines flood management and mitigation of disruption impacts using geospatial characteristics as part of data visualization. Case two incorporates trend analysis and sustainability assessment into energy portfolio transitions.
Four distinct contributions are made in this …
The Implementation Of Energy Sharing Using A System Of Systems Approach, Julia Morgan
The Implementation Of Energy Sharing Using A System Of Systems Approach, Julia Morgan
Doctoral Dissertations
"There is an increasing demand for renewable energy and consumers need more procurement options to meet their needs. Energy sharing provides a peer-to-peer (P2P) marketplace where prosumer electricity is redistributed to fellow energy-sharing community participants. This redistribution of prosumer electricity provides consumers with additional electricity suppliers, while also decreasing the load on the utility company. Though significant progress has been made regarding research and implementation of energy sharing, there is still room for growth when evaluating energy-sharing communities and defining appropriate community coordination based on end-user needs. The first contribution in this work identified nine characteristics of energy-sharing communities as …

Military Applications Of Geological Engineering, Stephen H. Tupper
Military Applications Of Geological Engineering, Stephen H. Tupper
Doctoral Dissertations
"This work examines the premise that military engineering and geological engineering are intellectually paired and overlapped in practice to a significant extent. Geological engineering is an established, albeit young, academic discipline that enjoys wide industry and civil demand and is supported by many professional organizations. In contrast, military engineering is an ancient, empirically derived training or "OJT" program with practice-based trade-associations that has narrow government-only utility. The premise is formed by decades-long observation of U. S. Army military engineer officers completing a Master of Science degree in geological engineering as a complement to their practice-based training in military engineering at …

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The national energy policy rightly addresses having coal assume a major share of the load carried by gas and oil. However, there is a basic strategy which is uniquely capable of solving much of the dilema. That strategy is to shift from our present oil/gas combustion energy economy to a coal - nuclear electric energy economy....
We can see that electric boilers are non competitive from an operating cost standpoint. But there is another way of applying electricity to the creation of useful heat and that is the heat pump. Several years ago, a Westinghouse feasibility study indicated that an …

Ratepayer Financing Of Solar Thermal Electric Commercial Demonstration Projects, Mark D. Jarmie, Jeff V. Conopask
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Commercialization of a new energy supply technology requires demonstration of its feasibility to potential customers at each staqe of development. While small improvements of proven energy supply svstems are usually privately pioneered, larger or more uniaue research projects are often delaved as economic and technical concerns are assuaged through public sector R&D funding. For solar thermal central receivers, even though their technical viability has been tested on a small scale, acceptance by utilities will require full-scale field experiments and commercial-sized demonstration plants.

Managing In An Energy Scarce Environment, John Amos
Managing In An Energy Scarce Environment, John Amos
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Present engineering management principles, operations research techniques, and economic theories were mainly developed dealing with only one scarce resource -- capital. Today, the engineer manager must consider another scarce resource -- energy. In the past, energy was never considered a major factor; i.e., equipment was considered a good investment if labor was reduced, regardless of energy cost. Many other managerial decisions are similar; therefore, the engineer manager must understand why many decisions based on traditional techniques may be misleading. The engineer manager must now utilize more complex engineering management techniques instead of evaluating only one factor or using rules of …

The Regulatory Nemesis, K. Daniel Hinkle
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy sources are truly regulated from the bowels of the earth to the flame tip. Local, state and federal governments, whether by design or blind ineptitude, have created a maze of administrative regulations that affect the development of both current and future energy sources. Rather than discuss regulatory horror stories, it is the purpose of this paper to discuss the impacts of this maze of regulations on current and alternate energy sources.
The first section will review 16 federal acts that make up the regulatory nemesis. The second section will review an example of the maze in action on a …
