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.

A city based on tourism, military installations, agriculture, and home to the first landing of Jamestown colonists, Virginia Beach boasts 28 miles of coastline along the Chesapeake Bay and Atlantic Ocean. Comparable to other beaches worldwide, the utter volume of visitors has taken its toll on the city, resulting in unsightly destruction and pollution. It is not unusual to read or hear about marine animals dying from eating or being trapped by waste that is deposited into oceans, or how oil spills are harmful to marine mammals, birds, and fish; yet somehow, it is uncommon to come upon the mentioning of butt litter, the most frequently littered item on Earth. Cigarette butts are strewn about the Virginia Beach boardwalk, resort strip, and the beach. In 2014, Clean Virginia Waterways collected more than 47,600 butts along streams, rivers, bays, and coastlines (CVW, 2015). With no smoking restrictions on the beach (or boardwalk,) tourists and local beachgoers alike frequently discard their butts on the sand and face no known consequences. Small but mighty, both smoked and unsmoked butts have severe impacts on waterways, economies, air quality, and public health. An economic analysis found that cities the size of San Francisco spend, on average, between $500,000 and $6 million annually to keep their beaches, streets, and parks clear of cigarette litter (Schneider et al., 2011).

This paper examines strategies to:
1. Drastically reduce butt litter within the city - Disposable/pocket ashtrays, additional butt/ash receptacles. 2. Increase community awareness on the economic impacts of litter - Organized cleanups, advertisements /marketing, partnerships with local NGOs.
3. Enhance citations and alternative penalties for those who discard their butts on the sand.
Additionally, this paper aims to discuss the potential implementation of a beach-wide smoking ban.

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.

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.
