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
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
