Staying Cool with Less Energy

James GowenWhen it comes to sustainability, one of Verizon’s challenges is going green while growing our business. Take the cloud, for example – one of the biggest developments in the telecommunications world today. On the business side, service providers such as Verizon are delivering “everything as a service” to its business customers. In other words, everything the customer needs -- such as computing, infrastructure and security -- resides “in the cloud” on Verizon’s network.  On the consumer side, customers are storing their digital media – from music to videos to high-def movies – in “the cloud”, so they can access it anywhere on any device.


It’s a wonderful digital age we live in, but here’s the challenge. More customers tapping into the cloud means more data centers and more electricity consumed. As a responsible company, Verizon wants to reduce its carbon footprint while it grows its business. And here’s one way we’re doing just that.


Verizon recently improved cooling efficiency at 24 of its U.S. data centers using intelligent energy management systems from Vigilent. This system places hundreds of wireless temperature sensors throughout each data center that are connected through an intelligent mesh network to on-site servers using energy management software. In other words, the system figures out the most optimal configurations for efficient air conditioning performance.


The result? We were able to turn off 40 percent of the computer room air conditioners in these data centers, which will provide anticipated savings of 55 million kilowatts annually. That will reduce our greenhouse gas emissions by more than 66 million pounds of CO2 each year. As for the air conditioning these data centers rely on? The system helped decrease average temperatures by two degrees Fahrenheit. Better performance using less energy? We’ll take that any day!


Last year, Verizon’s energy reduction and recycling initiatives around the globe reduced CO2 emissions by nearly 300 million pounds, leading to an improvement of more than 15 percent in the rate of emissions per terabyte of data, a new metric Verizon recently developed to measure carbon efficiency.
