How Eppley Airfield Could Be Reducing Your Power Bill (But They’Re Not), Cherry Pham

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

Eppley Airfield in Nebraska is spending $950 million on their renovation and services are still running, even during construction. Part of the airport’s renovation budget could be allotted to installing solar canopies. In the long run, airports with solar canopies reduces their own electricity expenses.

Carbon Markets: A New Opportunity For Farmers, Emma Wrede

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

Farmers have always known that healthy soil is their greatest asset to their success. Carbon markets are simply finding a new way to identify, measure, and compensate that value in a new way. In a time where every dollar counts, carbon credit markets can strengthen farmers’ margins and enhance their land health which they depend on. With continued research, improved regulation, and clearer guidelines, this system will work for both farmers and the environment.

Nebraska's Hidden Goldmine: Wind Power On Farms, Adelaide Witte

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

Nebraska’s been hesitant to go all in on wind energy. People often worry about things like noise, how turbines look, or even potential impacts on human health. Community concerns are valid and should always be acknowledged. However, addressing them doesn’t require putting all development on hold.

“The Good Life” Of Ai, Lauren Smith

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

Artificial Intelligence, or AI, is powered by data centers, sprawling warehouses of servers that require massive amounts of electricity and water to operate. The United Statesalready has more than 1,000 data centers, with nearly 400 more on the way.

Nebraska is next. Google is building a major new data center in North Lincoln, adding to the 18 operating across the state.

Our collective use of tools like ChatGPT, Google’s Gemini and Microsoft’s Copilot has fueled a boom in generative AI, and with it a surge in energy and water consumption.

The need for AI regulation isn’t a future concern. It’s …

The Land Competition Between Crops And Solar: Why Nebraska Farmers May Not Have To Choose, Jada Vogel

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

There are significant benefits that can come from implementing agrivoltaics on farms in Nebraska. The economic gains from the use of agrivoltaics alone may be sufficient to get individuals to pursue their use.

The Myth Of Clean Manufacturing, Andrea Phan

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

We must act now and reform renewable energy credits to reflect real progress. This means tightening Scope 2 rules so that renewable claims are tied to additional, time and location matched, clean power. It means rewarding measurable integration, so that real emissions are avoided, not waived by retroactive certificates. RECs can still play a role, but only in a system that demands we use the tools we already have.

Nebraska’S Best Option: Carbon Capture, Leah Bates

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

Some may argue that carbon capture technologies are not optimal due to their high costs or how they take focus away from implementing renewable energy sources. However, carbon capture and storage technologies are currently the best options in reducing carbon emission and Nebraska is leading the way.

Carbon Footprint Of Carrots In Western Australia, Christophe D'Abbadie, Saloomeh Akbari, Sang Ravindran

Horticulture research reports

This report presents the findings of a comprehensive carbon accounting study conducted on carrot production in the Myalup area of Western Australia.

The study reveals that carrot emissions are approximately 81 kg CO2e per tonne of carrot sold from the April harvest and 76 kg CO2e per tonne from the October harvest, when using rejected carrots for other economic uses. These figures represent competitive emissions intensities compared to international benchmarks.

Key findings include:

• Yield improvement is the primary driver for emissions reduction: Increasing productivity, without proportional input increases, offers the most effective pathway to lower emissions’ intensity while improving economic …

Evolution Of Agricultural Emissions Calculations In Australia: Methodological And Calculator Refinements And Their Impact On Western Australia’S Agricultural Carbon Footprint, Christophe D'Abbadie

Climate Science Published Reports

Greenhouse gas (GHG) emissions accounting is fundamental to positioning Australian agricultural products competitively in global markets, enabling supply chain stakeholders to make informed decisions, and understanding the trade-offs between market demands, policy requirements, consumer expectations, and intergenerational responsibilities.

Recent methodological refinements to emissions methodologies have enhanced the accuracy of GHG accounting in Western Australian (WA) agriculture. The Department of Primary Industries and Regional Development (DPIRD) has collaborated in these improvements through collaborative research with universities and federal agencies and advocacy for Western Australia-specific emission factors.

Methodological refinements have improved the accuracy of WA agricultural emissions estimates by 6% overall, providing …

Frameworks And Life Cycle Assessment For Reinforced Concrete Bridges For Sustainability In Transportation, Yu-Fu Ko, Jessica Gonzalez

Mineta Transportation Institute

Bridge structures are critical components of California’s transportation network, with reinforced concrete (RC) bridges being among the most widely used. Extending the lifespan of these structures can lead to significant reductions in environmental impacts. However, California’s frequent seismic activity has repeatedly exposed the vulnerability of existing RC bridges, highlighting the urgent need for seismic retrofitting and maintenance to improve infrastructure resilience against earthquakes and to increase sustainability. This research used detailed computer simulations known as nonlinear finite element models, which are highly detailed computer models, incorporating section damage indices to predict damage and assess structural deficiencies in RC bridges during …

A Feature Engineering Technique For Enhancing The Generalization Of Machine Learning Models In Estimating Crop Evapotranspiration, Gaku Yokoyama, Sohta Harigai, Shigehiro Kubota, Koichi Nomura, Gregory R. Goldsmith, Daisuke Yasutake, Tomoyoshi Hirota, Masaharu Kitano

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Accurate and precise estimation of evapotranspiration (ET) is crucial for understanding the terrestrial carbon, water, and energy cycles. While process-based models of ET, such as the Penman–Monteith model offer robust generalization capabilities, they are limited by the need for detailed parameters (e.g., stomatal conductance,) that are challenging to measure continuously. On the other hand, machine learning models can estimate ET by capturing relationships between ET and environmental variables without experimentally measuring model parameters. However, machine learning models face the challenge of limited generalizability. This issue is particularly significant given the uncertainty introduced by changing climatic …
