1. How to Be Virtually Green Explore greenercomputing.com (Jun 26 2009) Cloud Computing , Servers It's very interesting to me how certain principles can be broadly applied across industries. Take the principle of load diversity and full capacity utilization. This principle is used to great effect in the power sector, data centers and in some instances, buildings. In the power sector, electricity load-shifting was introduced in the late '70s and has enjoyed reasonable popularity ever since, particularly when a utility's generating reserve margin was low. Load-shifting means providing incentives for running certain equipment off-peak instead of on-peak. Perhaps the best-known example is the use of ice storage for off-peak cooling. Some engineers hate ice storage because it is "less efficient" than stand-alone chillers. In the small picture, this is correct. An ice storage system will use 7 percent to 8 percent more kWh than a chiller-only system yet, overall, using ice reduces CO2 emissions and fuel use, not to mention save tons of ...
