![]() For data centers and other critical facilities, the additional requirement to meet higher reliability standards will also be evaluated. The potential efficiencies, comparisons of savings of equipment and other advantages and disadvantages are also illustrated. A data center in Hamina, Finland, is reviewed for using seawater. This system is presented here for lake water use. started in 2000 in Ithaca, N.Y., and serves over 70 MW of cooling. The first deep lake water cooling system in the U.S. ![]() Using our natural resources in a more direct way can bypass inefficient cooling steps. To reach the energy saving goals, designers need to broaden their choices to find the most beneficial options available. Generating cooling on site using electricity from power plants is less efficient than planning ahead and using more localized cooling sources. As the need for energy to support these data centers rises, the need to find and use efficient cooling sources will also increase. With the expansion of cloud computing and increasing demands for online services, the number of data centers continues to grow throughout the world.
