Taking the Measure: IT and Energy:  I've heard these numbers verbally before, but not online; I've asked the author for the reseach citation.  "According to researchers at MIT, less than 1 percent of all commercial and industrial companies use advanced technology to measure and manage energy spend. On the other hand, nearly 100 percent of companies use advanced technology to measure and manage telecommunications spend.  Now consider that, according to the MIT researchers, the U.S. spend in electricity is about $270 billion per year while the U.S. spend in telecommunications is about $125 billion per year.

Does your company know down to the fraction of a minute how your telecommunications bill is derived?  Probably, and you can probably produce pages of reports showing spending by person, department and project. .. Can you also break out by building, department, project and individual worker how your electrical bill is derived? Or your heating bill? Or your air-conditioning bill? I doubt it, but that is where your next round of cost savings resides."
