3. The Navy Knows Cold-Ironing Navy ships have been “plugging-in” to pier-side electric services, referred to as “cold iron,” at Naval Base San Diego since the 1940s. Cold ironing is a shipping industry term that first came into use when all ships had coal-fired, iron-clad engines. When a ship would tie up at port without necessity to feed the fire, the iron engines would cool down, eventually going completely cold. “Cold iron” evolved into the Shipboard Shore Energy Management Program. Recently, Navy Secretary Ray Mabus stated that the Department of the Navy will produce at least half of shore-based energy requirements on installations from alternative sources by the year 2020. In light of this requirement, SSEM has proven to be an effective way of reducing energy consumption. -LT Lenaya Rotklein, USN 3 http://www.navyregionsouthwest.com/go/doc/4275/1216455/Reducing-energy-costs
