Energy Rebound As A Potential Threat To A Low-Carbon Future: Findings From A New Exergy-Based National-Level Rebound Approach, Paul E. Brockway, Harry Saunders, Matthew K. Heun, Timothy J. Foxon

University Faculty Publications and Creative Works

150 years ago, Stanley Jevons introduced the concept of energy rebound: that anticipated energy efficiency savings may be "taken back" by behavioural responses. This is an important issue today because, if energy rebound is significant, this would hamper the effectiveness of energy efficiency policies aimed at reducing energy use and associated carbon emissions. However, empirical studies which estimate national energy rebound are rare and, perhaps as a result, rebound is largely ignored in energy-economy models and associated policy. A significant difficulty lies in the components of energy rebound assessed in empirical studies: most examine direct and indirect rebound in the …

Stratigraphic, Geochemical, And Geochronological Analysis Of The Wolfcamp-D Interval, Midland Basin, Texas, Zachary S. Perlman

Theses and Dissertations--Earth and Environmental Sciences

Subsurface data derived from ~388 ft of drill core from Martin County (TX) were used to understand the depositional setting of the Wolfcamp-D, a petroleum producing interval in the Midland Basin. Elemental geochemistry collected via x-ray fluorescence revealed a highly variable depositional history marked by the deposition of diverse siliciclastic and carbonate lithofacies. Integration of multiple datasets resulted in the interpretation of nine lithofacies, whose deposition appears cyclical. Correlations between molybdenum and total organic carbon indicate slow recharge of bottom waters and anoxic/euxinicconditions within the basin. The presence of phosphatic nodules coinciding with siliceous black mudrocks suggested high levels of …

Development Of A Dynamic Cfd Model For Offshore Oscillating Water Columns With Non-Linear Interactions, Ken O'Connell

Theses

This thesis focuses on the development of a state of the art modelling technique for offshore Oscillating Water Column (OWC) type Wave Energy Converters (WEC) using Computational Fluid Dynamics (CFD). Current literature indicates a limited amount of work has been completed on studying these devices containing non-linear time dependent flow phenomenon. Initially, a 2D Numerical Wave Tank (NWT) is studied to reduce discretisation error in order to reproduce accurately propagating waves. Further development into a 3D domain permits the geometrical requirements of an OWC type spar buoy to be included.

In parallel, a single Degree of Freedom (DOF) model is …

Pyroelectric Ceramics As Temperature Sensors For Energy System Applications, Jorge Luis Silva

Open Access Theses & Dissertations

Temperature is continuously monitored in energy systems to ensure safe operation temperatures, increase efficiency and avoid high emissions. Most of energy systems operate at high temperature and harsh environments to achieve higher efficiencies, therefore temperature sensing devices that can operate under these conditions are highly desired. The interest has increased in temperature sensors capable to operate and in harsh environments and temperature sensors capable to transmit thermal information wirelessly. One of the solutions for developing harsh environment sensors is to use ceramic materials, especially functional ceramics such as pyroelectrics. Pyroelectric ceramics could be used to develop active sensors for both …

The Water-Electricity Nexus In California: Drought-Induced Risk To Thermal Electricity Generation, Timothy S. Hyles

Cal Poly Humboldt theses and projects

Investigating the possibility that drought might limit the water supply needed for thermal electricity generation in California, power plant water consumption data was compared to urban and agricultural consumptive demands to identify areas where power plants might contribute to regional water stress. To identify areas where power plants might be impacted by water stress, regional power plant, urban, and agricultural water demands were also compared to the available water supply. A list of power plants that would contribute most to regional water scarcity (individually and in aggregate) was highlighted, based on the plant’s water consumption volume, water-intensity, and water source. …

Human Resource Local Content In Ghana's Upstream Petroleum Industry, Papa Benin

Walden Dissertations and Doctoral Studies

Enactment of Ghana's Petroleum (Local Content and Local Participation) Regulations, 2013 (L.I. 2204) was intended to regulate the percentage of local products, personnel, financing, and goods and services rendered within Ghana's upstream petroleum industry value chain. Five years after the inception of Ghana's upstream oil and gas industry, a gap is evident between the requirements of L.I. 2204 and professional practice. Drawing on Lewin's change theory, a cross-sectional study was conducted to examine the extent of differences between the prevailing human resource local content and the requirements of L.I. 2204 in Ghana's upstream petroleum industry.

Ab Initio Study Of The Effects Of Humidity On Perovskite Based Hybrid Solar Cell Interfaces, Shantanu Rajendra Rachalwar

Browse all Theses and Dissertations

Despite the impressive success of perovskite-based hybrid solar cells, their widespread usage has been limited partially owing to stability issues under working environmental conditions. Among these, the effects of humidity are some of the most significant. Water intercalation generally degrades the material, shortens its useful life, and reduces the efficiency of photovoltaic energy conversion. Understanding the reasons for these effects can be achieved through detailed and accurate atomic-scale analysis. Here, we study water intercalation at the interfaces of perovskite-based hybrid solar cell material and TiO2 electrode. Accurate ab initio computer simulations are used to obtain structural and electronic properties. We …

Study Of Periodical Flow Heat Transfer In An Internal Combustion Engine, Xi Luo

Wayne State University Dissertations

In-cylinder heat transfer is one of the most critical physical behaviors which has a direct influence on engine out emission and thermal efficiency for IC engine. In-cylinder wall temperature has to be precisely controlled to achieve high efficiency and low emission. However, this cannot be done without knowing gas-to-wall heat flux. This study reports on the development of a technique suitable for engine in-cylinder surface temperature measurement, as the traditional method is “hard to reach.” A laser induced phosphorescence technique was used to study in-cylinder wall temperature effects on engine out unburned hydrocarbons during the engine transitional period (warm up). …

Structure Stability And Optical Response Of Lead Halide Hybrid Perovskite Photovoltaic Materials: A First-Principles Simulation Study, Siddharth Narendrakumar Rathod

Browse all Theses and Dissertations

A third-generation of solar cell is based on organic-inorganic hybrid perovskite materials. These have reached up to 22.1% conversion efficiency through exponential growth just within the last decade, compared to much longer improvement times for other photovoltaic technologies. Lead halide perovskites are among the most commonly used materials in this context. Despite the relatively large number of available works on some of these materials, in particular CH3NH3PbI3, others are less investigated. Here, we focused on CH3NH3PbCl3, CH3NH3PbBr3 and CH3NH3PbI3 for assessing structure stability and optical response. Using quantum-mechanics-based first principles approaches, we calculated the optimized structures of these three materials …

Mathematical Modeling Of A P-N Junction Solar Cell Using The Transport Equations, Surjeet Singh

Browse all Theses and Dissertations

While analytical models are limited in the situations that they can simulate, they are generally easier to implement than numerical models and provide a rapid view of the variables which affect a certain quantity. Analytical models are also very useful in educational situations; such as a graduate class on photovoltaics. The modeling of the interior workings of a solar cell can be complex and involved; and some of the equations can become quite lengthy. A focus of this thesis work is the derivation of the minority carrier density and minority current density equations for a p-n junction solar cell. The …

The details of monolayer assembly, molecular adsorption configuration, and resulting modification of electronic properties are important characteristics related to solar cell performance. These characteristics can be obtained through accurate computer …

Stop Fighting It Nebraska: Clean Energy Is Here To Stay, Nicholas Underwood

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

The state of Nebraska and more specifically the Nebraska Public Power District has so far shown a surprising reluctance to incorporate clean or renewable sources of power into its portfolio. The state’s reluctance is exemplified in their support for legal challenges to the Clean Power Plan put forth by the Obama Administration. NPPD in particular has decided to stick with coal as its primary fuel source and has even discouraged the construction of natural gas facilities in the state. The power utilities in this state need to develop a modern, clean energy system to avoid being left behind.

In a country where 30% of the population still believes that man made climate change is a myth, president Obama has made a daring effort to help fix the damage our country has already inflicted on our planet. By creating The Clean Power Plan (CPP) we’ve taken a step in the right direction as a country. The action that we take to limit our emissions within the next 10 years will likely determine the course of the rest of our existence.

In our current situation humanity has no choice other than to act, and act quickly. We have passed the …

Fossil Fuel Subsides Will Keep The Us In The Stone Age, Alexander Stejskal

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

Renewable sources will be the future of energy production for the United States. Clean sources of energy like wind and solar have been the topic of conversation for quite some time, and now they’re starting to show their ability to compete economically with fossil fuels.

Even as renewable sources of energy begin to show their gusto, they are still a part of a relatively new industry and new industries always need a little help getting off the ground. There are some forms of aid being provided for renewable sources of energy, like the production tax credit or PTCs, where the …

Solar, Why Not?, Emily Hergenrader

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

Imagine yourself standing outside for an hour wearing a black shirt on a 90-degree day. Now touch your shirt. Notice how warm it is? This warming is due to the sun’s energy. According to Daniel Nocera, a member of the Division of Chemistry at the Massachusetts Institute of Technology, that same heat from one hour of sun exposure is more energy than all of the energy consumed by humans in an entire year.

Energy is one of the hottest topics debated in our world today. Human existence on Earth depends on energy usage and the availability of its consumption. Due …

Why We Should Keep Worrying About The Atomic Bomb, Eric Davis

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

“… the members of the Bulletin of the Atomic Scientists Science and Security Board have looked closely at the world situation and found it highly threatening to humanity—so threatening that the hands of the Doomsday Clock must once again be set at three minutes to midnight, two minutes closer to catastrophe than in 2014…Meanwhile, as they slow the pace of disarmament, the nuclear weapon states have given other strong indications that they are committed to retaining nuclear weapons for the indefinite future” - Bulletin of the Atomic Scientists (2015).

Independent Energy, Ian Hall

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

In the world of energy, an elite selection of the world’s most influential leaders dictates the development of the world. The correlation between petroleum production and global influence is hard to ignore. The world needs energy to move and those with the energy control the movement. Saudi Arabia, Russia, and the US combine to contribute over a third of world oil production. OPEC countries however, dominate the vast energy markets around the world. Well inundated with regional conflict and hostile relations, OPEC countries remain volatile and on top of global energy production.

The energy industry has become extremely productive, fueling …

A Dynamic Power Grid For A Dynamic Age Introducing Les To A Pricing Mechanism That Assesses Demand, And Changes Every Hour, Marvin Christopher Cunningham

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

Lets say you knew someone who would buy a whole pizza when they were a little bit hungry, left their sink running when they weren’t using it, maxed out their A/C in their house when they were on vacation, and always kept their stove on just in case they wanted to cook something.

You would probably see this as horribly wasteful, and a terrible drain of money. But every time we pay our power bill, our prices assume we share these wasteful habits. The rate that we pay per kilowatt hour assumes customers are eating the whole pizza, even though …

Les To Increase Fixed Price, Nathan Blazek

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

Lincoln Electric System (LES) plans to increase the fixed amount customers pay each month and decrease the rate it charges for each kWh used.

This shift is claimed to be revenue neutral for LES. But for customers, it means they’ll save less money by turning off lights and buying more efficient appliances.

This policy is a sly and deliberate stab at ongoing conservation efforts. The decreased kilowatt pricing will give customers the perception that it is relatively unnecessary to decrease electricity usage if they are already paying a high price to initially have it. This new policy will even further …

Is Nebraska Really “The Good Life”?, Sarah Porath

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

For anyone who has ever lived in Nebraska, you know the state is filled with people who resist change. Nebraska is “The Good Life.” Any adjustments or modifications that could disrupt the lifestyle are not welcomed. The people who are elected into office clearly reflect this type of mindset.

It is time for Nebraska to get outside of their comfort zone. We need to move from the good life to the great, healthy, and progressive life by developing a state-wide Energy Efficiency Resource Standard or Goal.

20 states have Mandated Statewide Energy Efficiency Resource Standards and 8 states have Goals …

Fracking Chill, Nick Nardone

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

Hydraulic Fracturing or commonly known as fracking has caused a big boom in the oil and gas industry making it easier for us to extract oil and gas from the ground, but has serious side effects that as they cause harm to us and our environment. We should slow or stop fracking at once if we want a clean and healthy environment to live in.

Fracking has become widely popular in the last decade and has brought us benefits on the oil and gas side and with little lack of information and support it has been difficult to put restrictions …

The Great Plains: America’S Carbon Vault, William Davidson

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

As a nation we are starting a race against climate change, a competitor who has had a very long head start and only plans on picking up the pace. The Clean Power Plan has laid a blueprint to lower carbon emissions from fossil fuel burning power plants nationwide, a crucial step in recovering from decades of pollution. Meeting these goals will take years and greenhouse gasses will continue to accumulate throughout the process. Efforts beyond the scope of this plan must also be made in order to prevent emissions from sources not specifically addressed, namely sources of carbon that cannot …

Calculating The Methan-Matics Of Our Future, Victoria Salinas

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

In the first two decades after its release, methane, a green house gas, is 84 times more potent than carbon dioxide. Historically, atmospheric concentrations of methane remained fairly stable at around 750 ppb, significantly less than today’s levels of 1,800 ppb. Unfortunately, agricultural activity accounts for about one-fifth of total global greenhouse gas emissions, while the current production of ruminants contributes nearly 80% of these emissions due to their large populations, body size and appetites, and the anaerobic microbial fermentation that occurs during digestion. Because of methane’s severe impact on the climate, methane emissions, specifically due to the production of …

Willingness To Pay Today For A Cleaner Tomorrow, Yukihira Naoe

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

To a ten year old boy on a tedious trip across the country side, few views are more fascinating than a wind farm. Massive turbines spin slowly as if to emphasize their preposterous size and magnificence. In an era where increasing global attention is brought to climate change, renewable energy is carving its way into the minds of billions. This once free roadside attraction is now something that in the near future, we must pay and patronize, and this is where my literature begins, how willing are we to pay for renewable energy? Are you willing to pay to give …

An Exploratory Study On The Possible Effect Of Hydraulic Fracturing Activities On Air Quality In The Eagle Ford Shale Region Of Texas., Laura B. Fimibama

Electronic Theses and Dissertations

Eagle Ford Shale (EFS) play is one out of five major oil and gas formations in Texas, found in the South-Eastern region with approximately 30 counties. In addition to natural gas, it produces crude oil and petroleum liquids which in recent times has resulted in a surge in drilling due to a new drilling technology – hydraulic fracturing that injects massive quantities of water along with sand and chemical additives into a well to create tiny hairline cracks in rock formations. The success of this technology has made gas extraction more economically feasible. However, this technique has generated an array …

An Investigation Into The Origin, Composition, And Commercial Significance Of A Sedimentary Subsalt Formation: Keathley Canyon, Gulf Of Mexico, David Aaron Brassieur

University of New Orleans Theses and Dissertations

Sub-salt oil and gas formations in deep-water northern Gulf of Mexico are high priority targets. Advances in seismic processing allow for high-resolution, below-salt imaging. Understanding the modes of salt emplacement provide insight into sub-salt traps and potential drilling hazards.

A sub-salt sedimentary unit lies in the Keathley Canyon protraction. Autosutures created the transport-parallel lineaments of the upper surface of the unit. In addition, highly variable sediment aggradation rates created ramps, flats, and basal cutoffs along the base of the allochthon as salt and sediment competed for space. Seismic models identify modes of salt emplacement, salt/sediment interactions, and mechanisms responsible for …
