Description
Before the rise in renewable energy, few people considered the consequences of adding large amounts of intermittent power onto the grid. As renewable energy has become more prevalent, utility companies must adapt their business practices to accommodate these unique sources of power. This is leading to challenges on how best to manage a grid with large amounts of renewable power. Arizona Public Service (APS), the largest electricity provider in the state of Arizona, has more than 70,000 distributed solar customers on their grid and the number of solar customers increases every day. With this increase in distributed solar customers comes the solar duck curve—the phenomenon whereby solar produces energy during times of low demand. However, with the use of storage, the duck curve problem may be mitigated. This project examines the sustainability of three storage options: pumped hydro energy storage, compressed air energy storage, and lithium-ion batteries. Using several sustainability indicators, this project makes a policy recommendation to APS on the most sustainable choice for large-scale energy storage. This project found that compressed air energy storage was the most sustainable option for APS. This considered the impacts of compressed air on the environment, communities, and the costs of this storage option. One important aspect to acknowledge regarding this technology is that in its current form, it does emit some carbon emissions. However, the carbon emissions may have less of an impact if this storage facility can allow APS to use its renewable energy assets most efficiently and continue to use energy from Palo Verde, the nuclear facility in Arizona.

Description
This document contains a feasibility study that explores the necessity, collaborations, and
possible methods of installing a 1 megawatt lithium-ion battery storage facility at San Diego Gas
& Electric’s Century Park campus located in the Kearny Mesa neighborhood in central San
Diego, California. The battery will serve purposes of adding renewable energy to the energy mix,
reducing operations costs via peak shaving, an educational component for the region, and
meeting stringent State of California and California Public Utilities Commission mandates for
both renewable energy and battery storage capacity.

Description
The community of Gumantar in Lombok, Indonesia, one of the poorest regions of the island, is home to a large number of coffee farmers. Due primarily to production quality, these farmers struggle to earn a sufficient wage. While trying to provide for their families, the local environment often suffers. The persistent poverty has resulted in lower education levels, health care barriers, and decreased well-being. In an effort to empower the farmers and promote sustainable development, I have created a best practice guide that looks at five coffee production factors. The local farmers have specifically requested case supported, science-based information regarding these factors. The factors include farming techniques, drying practices, coffee specific small business skills, financial literacy, and coffee certification requirements. Access to information regarding these topics is intended to help reduce poverty, increase accessibility to quality education, and support local economic development, environmental health, and community health and well-being.

Description
This project focuses on building capacity for the long-term viability of the garden based learning program at Martin Luther King Early Childhood Center through cultivating relationships with local organizations and businesses. Building upon Matthew Waldman’s 2018 MSUS project work with this school and The Farm at South Mountain, this project’s purpose was to explore ways to integrate the greater school community and allow them to share their vision for an outdoor community space.
The intervention tool used to engineer this collaborative mindset was individual square foot garden boxes that each child in the 2019 student body was able to decorate and take home.
As a tangible piece of this Culminating Experience, I have installed a pollinator garden that has been registered with Monarch Waystation Program. This space serves as a celebration of the school’s mascot and provides a totem for the collective action of the community.
With the onset of COVID-19 and the implementation of local, state and federal guidelines, the school has been closed since March and has curtailed the anticipated deliverables.

Description
COVID-19 brought so much uncertainty into the world and has molded this project into what it is today. The first project journey that was chosen was meant to show the impact of how much plastic waste was being produced at Starbucks. Then due to COVID-19 yet again, it changed into how much paper waste there was within the State of Washington Department of Licensing (DOL) Business and Professions Division (BPD). DOL BPD is a state agency division that licenses over forty plus professional and business licenses to the residents of Washington state. Due to the pandemic, the project transformed into how the three pillars of sustainability impacts remote work within BPD. BPD is in this new and unique paradigm where the deliverable that was brought forth as this project completed are, “The 9 Benefits of Sustainability through Remote Work” (Appendix D) where this specifically showed DOL why remote work is sustainable and how it should be implemented even further throughout the agency. This list was put together with the benefits that best fit DOL BPD.
