The World Wide Web of Green: EDF Climate Corps Fellow explores global opportunities for Yahoo!

What do you get as a gift for the person who has everything? Though most of us won't have to face this dilemma until the holidays, I find that being an EDF Climate Corps Fellow at Yahoo similarly stretches my creative limits because I'm being asked to uncover energy efficiency opportunities at an already very green company.

Whether it's drawing inspiration from chicken coops to build data centers, using goats instead of lawn mowers, or pioneering an ‘open-source' model of sharing environmental hi-tech practices, Yahoo has an impressive record of thought leadership in the intersection of IT and green. Along with several other EDF Climate Corps Fellows in Silicon Valley, I am tasked to look far outside of the box to find energy efficiency improvements for my host company. With the majority of the ‘low-hanging' fruit already picked, my position requires me to search through all of Yahoo's world-wide operations for efficiency improvements.

My main project work so far has been to evaluate current power consumption metrics of Yahoo's domestic and international data centers, both for determining the company's current carbon footprint as well as scouting prospective sites for new centers. Such a job requires:

  • Researching countries where Yahoo could possibly build data centers that use renewable energy, and considering both the pros and cons of each option, including cost of electricity, incentive programs and tax implications.
  • Evaluating the expected Power Usage Efficiency of a data center in each location, which can often bring unexpected results. For example, India is a well-known hot spot for tech companies to source IT operations due to its low-cost labor and highly educated talent pool. However, a data center in India is likely to use power about as half as efficiently as one in the U.S., if not more, due to the hot and humid climate, among other issues.
  • Assessing all of the factors that Yahoo must consider (and balance) when building a data center – not just energy efficiency, but also data transfer speed, bandwidth, and physical server capacity.

I'm also now working on a project with a different global track: studying the Japanese Variable Refrigerant Flow (VRF), an air conditioning model that is popular in Asia and Europe, and my job is to see whether certain components at Yahoo's Sunnyvale, CA headquarters can be retro-fitted with this technology. Since these systems are designed to be installed using tiny piping that requires little additional drilling (a 550 year-old hotel in France was able to retrofit), I hope to reduce the HVAC Load in Yahoo's Headquarters by 20% - which could result in dramatic savings.

Having long had an interest in global strategy and operations, my work has really allowed me to pursue those functional interests while also building on my experience in the energy and high-tech verticals. With companies needing to implement energy efficiency on a global scale, I hope that my findings at Yahoo can have a similar international reach.
