The report examines the transition of U.S. Navy bases in the Southwest toward microgrids to enhance energy security and integrate renewables. It identifies five key findings: the need for more granular design requirements, a conflict between utility-scale renewable goals and microgrid security, the immediate value of enhanced control systems, the complexities of participating in California's electricity markets, and internal Navy bureaucratic barriers. The document recommends that the Navy, grid operators, and regulators collaborate to define reliability needs, quantify the business case, and remove regulatory hurdles to enable microgrid adoption.

The document argues that the 'nexus' of water, energy, and climate requires integrated modeling tools to avoid unwanted policy consequences. To address this, the Stockholm Environment Institute (SEI) linked its WEAP and LEAP systems. A California case study simulating the use of desalinated seawater to meet 5% of Southern California's urban water demand by 2049 found that while desalination could reduce water imports by approximately 300 million cubic meters per year in normal years, it would increase the water sector's electricity use by about 3 terawatt-hours and greenhouse gas emissions by 1.4 million tonnes of CO2e per year by 2049.
