PUE Is Not Necessarily a Measure of Sustainability

PUE - Power Utilization Effectiveness - is a common measure of energy efficiency for ICT facilities. We have often cited it in our articles, but we are mindful that efficiency does not necessarily lead to sustainability. Here are some areas where PUE can fall short.

Diesel Generators: ICT's Dirty Component

Belching diesel equipment is not what one imagines when visualizing the Internet and mobile communications. It turns out they play a significant role in ICT's consumption of fossil fuels and emission of GHG.

What Customers Look For In A Green ICT Facility

We're increasingly seeing data centers promote, and customers respond to, Green ICT features. Here are some customer perspectives and the results of a industry survey that reveals geographical differences.

How Eco is "Eco" Gear?

Evidence of Green ICT on the information and telecommunications industries is everywhere. Gear is becoming more energy efficient, renewable energy is increasingly in favor, and product content and lifecycles are starting to be scrutinized. So what defines "eco" gear in 2012?

Apple's Data Center

Apple's 2012 Facilities Report provided detail on on the sustainability features, ranging from 'free air' cooling to real-time power monitoring, in Apple's Maiden (NC-USA) data center. A more recent report commits to 100% renewable energy.

Impact of Green Data Centers

A Pike Research report says that the trend to greener data centers will yield a significant GHG slowdown as well as drive a substantial market opportunity. Here are some of the top-line numbers from Pike.

Ethernet-Powered LED Lighting

Facebook mentions in passing that its highly efficient Prineville data center uses "Ethernet-powered LED lighting [to] reduce the total energy required to run the facility." Additional information about what exactly Facebook has done is hard to fine. What is Ethernet-powered LED lighting?

PV Solar and DC Power

Photovoltaic (PV) solar is promising source of on-site renewable electricity generation for ICT infrastructures. Solar PV generates DC power; computers and other e-devices run on DC power. What are the challenges and opportunities?

Oracle: Data Center Sustainability Improving

Oracle's latest Next Generation Data Centre Index compares today's situation ("C2") with that of a year ago ("C1") for Europe and the Middle East. Findings are positive but mixed from a Green ICT perspective.

Facebook Publishes Server & Data Center Designs, PUE Performance

We first looked at the impact of social media in 2007 with Virtual Worlds Leave a Real World Carbon Footprint. Since then, there has been increasing focus on the mega-data centers that underlie the most popular services. Facebook, who has opted for a custom server approach to reducing PUE, has take the unique step of publishing its server and facility designs. Facebook calls this the Open Compute Project (OCP). The Project just picked up a surprising ally - Greenpeace.
