Data centers and energy savings
Some advice on how to save energy in data centers to achieve net-zero energy.
One of the best ways to achieve energy savings in computing is to reduce the amount of IT equipment. Server virtualization is a popular and effective way to eliminate a large number of underused physical servers while providing the same level of service with a small number of highly used servers.
In a data center, there is opportunity to reduce HVAC energy by employing row containment strategies to reduce the mixing of cool supply air with hot exhaust air. In-rack cooling solutions offer even greater savings by reducing the volume of conditioned space from the entire data center to the inside of the racks.
From the end-user perspective, desktop computers should be replaced with energy-efficient laptops. Some facilities have eliminated hardwire Ethernet and use wireless for end-use devices instead. This eliminates networking equipment that would otherwise consume energy 24/7.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
