The growth in data center size and quantity increases concerns about the sector's growing energy usage and environmental impact, specifically carbon and water footprints. In fact, electricity consumption is one of the largest producers of the above-mentioned DC environmental footprints. However, predicting the embodied scope 3 carbon dioxide equivalent emissions and both on-site and off-site water consumption from purchased electricity for end users in the United States is often challenging due to electricity transmission within complex interconnected power grids. This dissertation proposes a novel method to quantify the lifecycle scope 3 carbon emissions and off-site water consumption that embedded in electricity at a much finer scale - the county-level - with the aid of explicit finite-difference theory and economic input-output theory. Results show that significant spatial variation of scope 3 carbon emissions exist within a large aggregation area. This dissertation also proposes a new metric to quantify the impact of data center water consumption on regional water availability by including both onsite and off-site water consumption using the proposed model. Furthermore, this dissertation explores the feasibility of reducing environmental burden through on-site renewable energy (i.e., solar photovoltaic) power generation and both airside and water-side economization technologies. It is found that up to 16.4% of carbon emissions and up to 16% of water stress impact can be saved by implementing airside economization in traditional air-cooled data centers. Results also reveal that data center energy efficiency can be improved by up to 11.2% when both economization technologies are implemented with a chilled water-cooling system, which yields to up to 11% of carbon emissions reduction. Furthermore, this dissertation reveals that it is financially beneficial to have onsite photovoltaic power generation in locations with high electricity prices and sufficient solar availability (i.e., Hawaii).
