Effect Of Cloud Cover On Optimum Orientations Of Fixed Solar Panels For Maximum Yearly Energy Collection, Prethew Prasad

Browse all Theses and Dissertations

The amount of cloud cover present in the sky is a significant factor when determining the solar radiation impinging on a solar panel. The optimum tilt required to achieve maximum energy impingement on a surface is also influenced by the amount of cloud cover. This work presents a method for determining the optimum tilt angle for a fixed solar panel when a set amount of cloud cover is present in the sky. Fixed tilt angles that have the most incident solar energy over the course of a year as a function of cloud cover, latitude, and azimuthal angle orientation are …

Optimisation Of Retrofit Wall Insulation: An Irish Case Study, Rakshit D. Muddu, D M. Gowda, Anthony James Robinson, Aimee Byrne

Articles

Ireland has one of the highest rates of emissions per capita in the world and its residential sector is responsible for approximately 10% of total national CO2 emissions. Therefore, reducing the CO2 emissions in this sector will play a decisive role in achieving EU targets of reducing emissions by 40% by 2030. To better inform decisions regarding retrofit of the existing building stock, this study proposes Optimum Insulation Thicknesses (OIT) for typical walls in 25 regions in Ireland. The calculation of OIT includes annual heat energy expenditure, CO2 emissions, and material payback period. The approach taken is based on Heating …

Development Of A Computer Model To Simulate Battery Performance For Use In Renewable Energy Simulations, Arjun Sundararajan

Browse all Theses and Dissertations

Renewable and clean energy has been the driving force behind the booming storage industry. The need for producing energy from clean and quickly replenishable energy sources has never been as high as it is now. However, renewable energy only supplies a little over a quarter of the world’s electricity needs and much less of the world’s total energy requirements. One reason is the intermittent nature of renewable energy. Inexpensive and convenient storage technologies are required to solve this issue. It is believed that batteries offer the most viable solution to conquer the problem of renewable energy intermittency. To aid the …

Investigating The Effect Of Electrolyte Concentration And Charging Protocol On Materials Utilization In Rechargeable Zinc Manganese Dioxide Batteries, Snehal H. Kolhekar

Dissertations and Theses

Achieving a highly cyclable, high energy density battery with MnO₂ cathodes encounters many obstacles. Chief among these is the inability of the widely-used γ-MnO₂ polymorph to retain its structural integrity when cycled to near full one-electron discharge capacity, which is about 280mAh/g for commercially available electrolytic manganese dioxide (EMD). In this one-electron range, discharge occurs by proton insertion producing Mn⁺³ which then reverts to γ-MnO₂ on charging. In the first part of the thesis, we investigate the root cause of failure of MnO₂ cathodes under deep cycling in the one-electron discharge range and establish a …

The Eicda: What Is It, And Why Is It Right For Nebraska?, Samantha Markus

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

For decades, humans have been pumping greenhouses gases into the atmosphere, and we are finally starting to see some of the damages. Global temperature has risen 1.76°F when compared to the twentieth century. Within Nebraska, we are seeing an increase in heavy rain events and extreme hot days, both of which negatively impact agriculture. These changes are becoming more devastating as each year passes with no action.

Biden’S “Blue” Hydrogen Plan Is Not The Answer, Ryan Martz

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

The excitement about hydrogen as a fuel and energy source is similar to buying an electric vehicle (EV) thinking it will reduce your personal CO₂ emissions. On the surface, it seems great! No greenhouse gas emissions while driving is certainly better than the greenhouse gasses released from a normal combustion engine car, but when you consider other effects, it’s no longer as great. What if the grid that you plug your EV into is powered primarily by coal? What about the environmental and human rights impacts of mining the materials to make the batteries? What about the lack of …

Loss And Damage: The $100 Billion Promise ‘The Leaders’ Failed To Keep, Abbie Williams

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Imagine you decide to install solar panels on your house. You want to do your part in combating the climate crisis as well as save your family money. You’ve done your research about which panels to get and exactly how to position them on your home. Then you find out that your neighborhood doesn’t allow solar panels because someone decades ago decided they weren’t aesthetically pleasing.

It's About Time Nebraska Ditches Coal, Riley Johnson

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

For too long now, Nebraska has relied on coal from our western neighbor, Wyoming. While this proximity to Wyoming’s coal mines has led to cheap coal and cheap energy prices, it has made us reliant on out-of-state coal companies. It's great that energy is kept cheap using coal, but all of our money is getting sent out of state. Why send all of our money out-of-state when we can keep Nebraskan’s hard-earned money in Nebraska. Our beautiful state has an extremely large potential for renewable energy that we fail to utilize.

30 By 30, Laron Core

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

Biden’s 30 by 30 plan, a regulatory approach to conservation, an imminent response to environmental action, a promise of inclusivity to all stakeholders. Or a broken promise in the making, an environmental policy inadequate to deliver sufficient results to its stakeholders? I am set to believe Biden’s 30 by 30 plan could very well be DOA.

Evaluating The Feed-In Tariff Policy In The Philippines, Joyce Marie P. Lagac, Josef Teofisto T. Yap

Ateneo School of Government Publications

To address the problems of climate change and energy security; the Philippines enacted the Renewable Energy (RE) Act of 2008. The law mandated the Feed-In Tariff (FiT) policy; which was designed to provide a guaranteed fixed price to RE investors for 20 years to develop renewable technology. This paper aims to evaluate the effectiveness of the FiT policy in promoting renewable energy development in the Philippines by assessing its costs and benefits. Data show that while the FiT has led to an increase in RE generating capacity; the share of renewable energy in the country has been declining since 2011. …

An Investigation Into Historical And Contemporary Breeding Occurrence Of The Ferruginous Hawk In Kansas, Erica Clark

Master's Theses or Doctor of Nursing Practice

The Ferruginous Hawk (Buteo regalis) is the largest Buteo species occurring in grasslands, nesting along bluffs, buttes and isolated trees. In Kansas, the Ferruginous Hawk is listed as a Species of Greatest Conservation Need, Tier II. A previous study on Ferruginous Hawks nesting in Kansas during the years of 1979 to 1987, with sporadic visits from the 1990s to 2000, revealed that the most productive nesting territories were inaccessible to predators, placed on rocky ledges and the surrounding landscape was over 50% rangeland. I revisited 82 of the 111 historic nest territories in the summers of 2019 and …

Petrographic And Core Analysis Of The Jurassic Norphlet Formation: A Case Study In The Lithofacies Control Of Diagenesis And Porosity In The Flomaton Field, Al, Jarrett Thomas Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study includes a sedimentologic and petrographic study of cores and thin-sections from the Jurassic Norphlet Formation in the Flomaton Field in southern Alabama to define a specific paragenetic history of each facies encountered and to identify key controls on reservoir quality. Eolian dune, nearshore, sand flat, and wadi facies were likely encountered in Norphlet core and thin-section samples that displayed a high degree of heterogeneity between them in terms of porosity, grain contacts, cement abundance/type, intergranular volume, and overall diagenetic processes. These distinct petrographic differences suggest that the paragenesis in the Flomaton Field is primarily facies controlled. The eolian …
