Smoke, Air, Fire, Energy (Safe) In Rural California: Critical Reflections On An Interdisciplinary Research Collaboration, Deepti Chatti, Carisse Geronimo, Cassidy Barrientos, Jana Ganion, Malcolm Moncheur, Peter Alstone Phd, Shawn Bourque, Tanya Garcia, Tesfayohanes Yacob

Humboldt Journal of Social Relations

This article provides a synthesis of the interconnected problems of tenuous energy access, wildfires, and exposures to high air pollution in Indigenous communities in rural California through the lens of ongoing collaborative research being carried out by researchers at Cal Poly Humboldt, Schatz Energy Research Center, Karuk Department of Natural Resources, and the Blue Lake Rancheria Tribe. The collaboration is funded by the Strategic Growth Council of the state of California, and we hope is the beginning of a longer term relationship between all partners. We are an interdisciplinary team of researchers drawing on energy engineering, air pollution science, and …

Assessing The Potential And Pathways For Renewable Energy Transformations In Orleans, California, Malcolm Prescott Moncheur De Rieudotte

Cal Poly Humboldt theses and projects

In what is now known as the state of California in the United States, the Karuk Tribe is interested in deploying a renewable-powered microgrid in the rural community of Orleans to improve electricity system reliability and resilience to address a wide range of challenges, including extreme events such as wildfires. This study assesses the potential of local distributed renewable energy and battery storage to meet Orleans' energy needs today and in the increasingly electrified future using an energy model. It also identifies existing cultural and social priorities for energy technology along with structural barriers to renewable energy adoption and the …

Techno-Economic Feasibility Of Electrifying Food Markets In Nigeria With Biogas Hybrid Mini-Grids, Demi Temitope Ogunwo

Cal Poly Humboldt theses and projects

This thesis explored the feasibility of electrifying a food market in an urban city in Nigeria with a hybrid biogas-powered mini-grid. Under the Energizing Economies Initiative of the Rural Electrification Agency of Nigeria, nine markets in the country currently receive constant access to electricity via hybrid mini-grid systems. As a majority of these systems are diesel-solar-battery systems, this thesis explored the use of biogas generators as a substitute for diesel generators in hybrid mini-grids for food markets. A fruit and vegetable market in Ketu, Lagos was used as a case study for the research. The research for this thesis was …

Exploring Renewable Energy Futures In Humboldt County Consistent With The Goals Of California’S Renewable Portfolio Standard, Amin M. Younes

Cal Poly Humboldt theses and projects

Humboldt County has abundant wind, solar, and biomass resources, but has made limited progress towards the state’s 2045 requirement of 100% clean electricity. A recently rejected onshore wind project showed that technically and economically viable projects can fall to social and political challenges, emphasizing the need for social considerations in renewable transitions. I therefore integrated community members’ preferences into modeling of RPS-consistent renewable energy scenarios in Humboldt County. My model suggests that offshore wind, utility-scale solar, distributed solar, and biomass power are technically and economically viable sources of significant local generation at varying costs.

In interviews with energy-engaged residents, I …

Automatic Power Management For Instructional Computers At Humboldt State University: A Calculation Of Potential Energy Savings And Greenhouse Gas Emissions Reductions, Nicholas F. Flenghi

Projects

Computers consume an estimated 5,610 GWh per year in California alone. Much of that energy is consumed by computers that are not being used. In this project, detailed user login data are used to estimate the energy consumption of instructional computers at Humboldt State University (HSU) over the course of one semester. The data are also used to estimate the potential energy savings from automating the shutdown process. Potential cost savings and greenhouse gas (GHG) emissions reductions resulting from implementing an automatic-shutdown power management plan are also calculated.

There are approximately 1,000 computers used for teaching and learning purposes at …
