Sustainability through use of seawater for space cooling — Applications in California & Florida

The paper describes a sustainable strategy of using seawater for space cooling on large scales. The temperature of deep seawater can be around 38degF about 2,500 ft below sea level, which makes the seawater an excellent coolant, resulting in significant energy savings of up to 90% compared to electric cooling. It is estimated that Florida and California could reduce their peak electricity demands by about 5-10% if deep seawater is used extensively for space cooling, which would avoid CO₂ emissions by millions of tons annually.
