Bidding Strategy For A Wind Power Producer In Us Energy And Reserve Markets, Anne Stratman
Bidding Strategy For A Wind Power Producer In Us Energy And Reserve Markets, Anne Stratman
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
Wind power is one of the world's fastest-growing renewable energy resources and has expanded quickly within the US electric grid. Currently, wind power producers (WPPs) may sell energy products in US markets but are not allowed to sell reserve products, due to the uncertain and intermittent nature of wind power. However, as wind’s share of the power supply grows, it may eventually be necessary for WPPs to contribute to system-wide reserves. This paper proposes a stochastic optimization model to determine the optimal offer strategy for a WPP that participates in the day-ahead and real-time energy and spinning reserve markets. The …
Will Saf Turbocharge The Corn Ethanol Market?, Richard Perrin, Lilyan Fulginiti, Felipe Miranda De Souza Almeida
Will Saf Turbocharge The Corn Ethanol Market?, Richard Perrin, Lilyan Fulginiti, Felipe Miranda De Souza Almeida
Cornhusker Economics
The long-run outlook for the corn ethanol industry is questionable, due to a transition to electric and hybrid vehicles. One source of hope for the long run is the potential demand for producing Sustainable Aviation Fuel (SAF). SAF is a key component in the United States Aviation Climate Action Plan, a path to net-zero greenhouse gas (GHG) emissions in the aviation industry by 2050. Demand for ethanol for SAF offers hope to the ethanol industry, but it depends a great deal on policy decisions that are being made now. Here we sketch out this story.
Based on the information available …
Why We Should Have More Walkable Cities, Alexander Huddleston
Why We Should Have More Walkable Cities, Alexander Huddleston
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The walkable city is something that is seen all over Europe but is a rarity in the United States. The rise of cheap oil in the first half of the 20th century led to the expansion of the suburbs and a car culture that we just can’t get away from. Our cities are now so spread out, causing more and more pollution and damage done to our environment. There is a lot that we know about this issue and the solutions that we can get done to fix it. America is stuck in a car culture that is so hard …
Eminent Domain: Unconstitutional, Unjust, And Unnecessary, Ashley Norris
Eminent Domain: Unconstitutional, Unjust, And Unnecessary, Ashley Norris
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Perhaps the most important undertaking of our time is the ubiquity of sustainable energy vital for the continuation and improvement of living conditions worldwide. The utmost care must be taken with the means used to achieve this feat. The fossil fuel industry has used and abused eminent domain since its inception. Ironically, environmental advocates now propose the same means to a cleaner, greener end. The taking of private land for private development, regardless of intent, is unconstitutional, unjust, and unnecessary. The Fifth Amendment states: “…nor shall private property be taken for public use, without just compensation.”
As stated by the …
Sound Energy Could Change The World, Tyler Bugiel
Sound Energy Could Change The World, Tyler Bugiel
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The energy crisis is a problem that has been growing more concerning for many years, and yet there has not seemed to be a good solution to the problem. That being said, I think that there is a solution that has not been explored thoroughly enough, that solution being sound energy. Solar and wind are both energy systems that use natural resources and things that occur on a day to day basis to convert those things into energy, but sound has not been explored as much.
The Essential Role Of Fossil Fuels In Combating Climate Change, Ivye Meyer
The Essential Role Of Fossil Fuels In Combating Climate Change, Ivye Meyer
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Fossil fuels have been essential to the living standards enjoyed by the industrialized and developed world. Since the Industrial Revolution, non-renewable sources, including coal, oil, and natural gas, have been our first choice in energy generation. Fossil fuels have also become appealing to developing nations, as they require inexpensive sources of energy to increase their standards of living. These factors contribute to fossil fuels comprising over 80 percent of the current global primary energy demand, undeniably making them a vital part of our daily lives. The necessity for upcoming change in energy production does not require the exclusion of fossil …

Navigating The Green Skies: Why Saf Is The Wrong Path To Take, Cameron Cannon
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
With its promise of a significant decrease in greenhouse gas emissions, sustainable aviation fuels, or SAFs, have been hailed as an environmentally friendly substitute for conventional aviation fuels. SAFs are made from sustainable resources such as plant biomass, waste oils, or agricultural wastes and are intended to mitigate environmental issues. On closer examination, though, this solution's intricacy becomes clear. Grab your mental compass and journey with me as we discover why SAFs would lead us the wrong way.
Producer Long-Term Marketing Opportunities With Ethanol Plants, Austin Harthoorn, Logan Lloyd, Cory Walters, Kate Brooks
Producer Long-Term Marketing Opportunities With Ethanol Plants, Austin Harthoorn, Logan Lloyd, Cory Walters, Kate Brooks
Cornhusker Economics
Commodity marketing operates in a complex decision environment with constant information flow, which can conceal long-run financially profitable marketing opportunities for producers. In the corn marketing space, the competitive role of ethanol plants throughout the state may provide producers with long-run financial gains by strategically approaching marketing decisions. In this article, we characterize whether producers can gain financially from strategically marketing corn to ethanol plants. For example, do ethanol plants provide a better long-run return from pre-harvest hedging, spring sale, or harvest sale?
We investigate three important contracting times--forward contract for harvest delivery (called pre-harvest hereafter), harvest delivery, and spring …
Carbon Farming: A Preliminary Economic Analysis Of Carbon Credits For No-Till And Cover Crops, Drew Havens, Richard K. Perrin, Lilyan E. Fulginiti
Carbon Farming: A Preliminary Economic Analysis Of Carbon Credits For No-Till And Cover Crops, Drew Havens, Richard K. Perrin, Lilyan E. Fulginiti
Cornhusker Economics
Summary Based on experimental data about the amount of carbon sequestered and estimated implementation costs, our preliminary results show that the average cost of sequestering carbon via no-till (about $22 per ton of CO2e) appears to be much lower than the $51 per ton social value of sequestering that ton. In contrast, our preliminary results show that the average costs of sequestration via adoption of cover crops is much higher, about $60 per ton. Depending on how accurate soil carbon models are in predicting sequestration on individual fields to qualify them for enrollment, reimbursement costs for planting cover …
Bridgeport Poised To Be Site Of Nebraska’S Next Environmental Catastrophe, Kjersten Hyberger
Bridgeport Poised To Be Site Of Nebraska’S Next Environmental Catastrophe, Kjersten Hyberger
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Bridgeport Ethanol LLC is Nebraska’s first ethanol plant to be under contract for Carbon Capture and Sequestration (CCS) in the state. Despite ongoing safety concerns by federal regulators and organized opposition from affected landowners, Carbon America is pushing forward with their plans to have the Bridgeport CCS facility operational by 2024. At a time when Nebraska has barely begun cleanup of the AltEn disaster in Mead, and the agrochemical contamination levels in our soil and groundwater are at historic levels, we cannot carelessly add one more pollutant to the mix.
In May of this year the Legislature passed the Nebraska …
Why Energy Efficiency Is Needed In Rwanda, Jean Ishinzibigwi
Why Energy Efficiency Is Needed In Rwanda, Jean Ishinzibigwi
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Perspective on the benefits of energy efficiency and cost savings on energy was changed by the experience of working with the Nebraska Industrial Assessment Center. Visiting various industrial locations in Nebraska to see how different energy-saving techniques are employed to save money on energy costs and reduce energy waste. Rwanda can put several ideas into action to lessen the energy loss, which is too much now.
The government's Ministry of Infrastructure (MININFRA) and other departments are crucial to Rwanda's energy sector. The primary ministry in charge of developing renewable energy is MININFRA (methane, peat, geothermal, solar and wind energy). The …
Carbon Capture Is Not Climate Action, Bella Devney
Carbon Capture Is Not Climate Action, Bella Devney
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
A new technology is being brought to Western Nebraska in the form of Carbon Capture and Storage in the name of climate action, but the health of Nebraska’s environment and people are being ignored. Bridgeport Ethanol Plant announced this fall that they plan to begin building technology that will capture and store “175,000 tons/yr” which is a small percentage of the 4,577 million tons emitted by the US in 2020.
Carbon can be captured from the atmosphere itself or in the Ethanol Plant’s case from the point of the CO2 production. After carbon is captured from the plant’s smokestack, it …
Stop Methane Emissions, Jacob Anderson
Stop Methane Emissions, Jacob Anderson
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
We all know of the worldly issue called global warming. A huge cause of global warming is the emission and buildup of greenhouse gasses in the atmosphere. Carbon dioxide is the leading contributor to global emissions at 74.4% and methane is second at 17.3% (Our World in Data 2019). On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022
which includes a charge that starts in 2024 at $900 per metric ton of methane emitted and will raise to $1500 by 2028 (CRS). This should introduce an incentive for facilities to update their plant, machinery, and equipment …
Nuclear Energy, Evan Detina
Nuclear Energy, Evan Detina
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The use of nuclear power as a primary energy source is a controversial discussion. However, if reversing or stopping the effects of climate change is our main goal, then this is a top contender. Fossil fuels account for 34 billion tons of emissions annually according to Ritchie, Hannah, et al. (2020). Instead, we can create energy through nuclear fission. I believe nuclear energy should become a much larger player in the energy game.
The first practical use of nuclear power became apparent on December 2, 1942 when a physicist, Enrico Fermi, developed a self-sustaining nuclear fission reaction at the University …

Puerto Rico Left In The Dark, Again, Eulices Garcia
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Puerto Rico, the United States third largest island, often gets overlooked when hurricane season comes and goes. Where most of the attention goes to the Florida peninsula or East coast, Puerto Rico is still one of America’s closest territories. As part of America’s extended family, Puerto Rico should not be overlooked when natural disasters occur. When these disasters happen, they can have a tremendous impact on the island itself and the people in it. One major concern that has not been truly fixed yet is the energy crisis in Puerto Rico. Whenever storms hit, there is always a possibility of …
Big Blue Wind Project: Why Solar May Be A Better Solution For Nebraska's Energy Future Than Wind, Page Nippert
Big Blue Wind Project: Why Solar May Be A Better Solution For Nebraska's Energy Future Than Wind, Page Nippert
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
With nonrenewable resources such as coal and oil causing greenhouse gas emissions, a shift to renewable resources is needed not only to reduce CO2 emissions, but also to allow energy independence. The switch to renewable resources is vital, and in Nebraska, these resources are being introduced commonly as solar and wind farms depending on the area.
NextEra Energy is proposing The Big Blue Wind project in Jefferson County. I’m opposing this project for reasons similar to why it’s being proposed – for the environment and the community.
The project aims to benefit the community economically by creating jobs, county …

Are Electric Cars A Solution In Rwanda?, Elysee Ndayishimiye
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Numerous studies have been conducted that demonstrate how environmentally friendly electric vehicles are. They produce fewer greenhouse gases, which makes them an effective way to reduce both air pollution and greenhouse emissions. In order to combat rising air pollution and support a green city initiative, Rwanda considered introducing more electric vehicles. The Global Electric Mobility Program, run by the United Nations Environment Program (UNEP), aims to assist low- and middle-income nations in switching from conventional (gas) to electric vehicles. Rwanda has joined this program. Due to the high cost of switching to electric vehicles in poor nations like Rwanda and …
New Natural Gas Pipeline Benefits Europe And Africa, Victor Moreno Lozano
New Natural Gas Pipeline Benefits Europe And Africa, Victor Moreno Lozano
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
European countries have agreed to start filling up their natural gas gap, with the new natural gas pipeline from Africa. Nigeria and Morocco agreed to develop this pipeline in 2016, but after the beginning of the Ukraine-Russia war, things have speeded up.
After the economical punishments Europe imposed on Russia, Russia decided to increase the price of the natural gas exported to Europe and decrease the amount of gas. Most European countries have a big dependency on Russia's natural gas, countries like Germany import 50% of their natural gas from Russia.
Since winter is coming up, European countries are dealing …
Multi-Criteria Evaluation Model For Classifying Marginal Cropland In Nebraska Using Historical Crop Yield And Biophysical Characteristics, Andrew Laws
School of Natural Resources: Dissertations, Theses, and Student Research
Marginal cropland is suboptimal due to historically low and variable productivity and limiting biophysical characteristics. To support future agricultural management and policy decisions in Nebraska, U.S.A, it is important to understand where cropland is marginal for its two most economically important crops: corn (Zea mays) and soybean (Glycine max). As corn and soybean are frequently planted in a crop rotation, it is important to consider if there is a relationship with cropland marginality. Based on the current literature, there exists a need for a flexible yet robust methodology for identifying marginal land at different scales, which …
Sources Of Variability And Uncertainty In Food-Energy-Water Nexus Systems, Heydi Calderon-Ambelis, Deepak R. Keshwani
Sources Of Variability And Uncertainty In Food-Energy-Water Nexus Systems, Heydi Calderon-Ambelis, Deepak R. Keshwani
Biological Systems Engineering: Papers and Publications
A nexus approach contributes to the strategic allocation of resources to secure food, energy, and water for the world population. Integrated models considering the complex interactions across food, energy, and water (FEW) enhance decision-making and strategic planning towards resilience. However, a significant number of the existing integrated models leave unaddressed the inherent variability and uncertainty present in the FEW sectors. Here, we review the importance of characterizing variability over spatial and temporal scales and the importance of decreasing the uncertainty present within a FEW nexus systems. The review also discusses existing modeling tools that address variability and uncertainty on single …

Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad
Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
Power systems are getting more complex than ever and are consequently operating close to their limit of stability. Moreover, with the increasing demand of renewable wind generation, and the requirement to maintain a secure power system, the importance of transient stability cannot be overestimated. Considering its significance in power system security, it is important to propose a different approach for enhancing the transient stability, considering uncertainties. Current deterministic industry practices of transient stability assessment ignore the probabilistic nature of variables (fault type, fault location, fault clearing time, etc.). These approaches typically provide a conservative criterion and can result in expensive …

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
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.

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
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 …

Rwanda To Phase Out Polluting Vehicles By 2040, An Efficient Strategy To Mitigate Global Warming Effects?, Josue Kwizera
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
Passenger vehicles are major pollutants because on average a typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. I highly support the idea that Rwanda joined on November 11, 2021, a group of countries at the COP26 UN climate talks that have made an agreement to end polluting vehicles by 2040. Rwanda is a landlocked country with a 12.95 million population as of 2020(world bank). Rwanda currently has over 221,000 registered vehicles; 83980 are passenger vehicles, 114,900 vehicles (52 percent of those vehicles) are motorcycles and the rest include public transports (buses and minibuses) and trucks …

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.
