It’s more than 20 years now from the first collective industry
recognition (Energy Star ratings) and the desire to do something about reducing
power consumption by IT equipment. The cycles of heightened awareness and hype
coincide with economic cycles or at times a paradigm change brought about by
new technology or use of existing technology like virtualization or cloud
computing. So when one of the organizers asked me to talk about Green IT, I was
perplexed on the unexpected resurgence; or was it a red herring or just a slot
filler ?
Researching the market beyond personal experience to understand the
current traction and prominence of Green IT, I started talking to CIOs to
understand their journey or milestones on the subject; I was hoping to use some
of the insights in my presentation to an audience of CIOs. Thus over the next few
weeks the data points that I gathered did not focus on public or private
clouds, but to understand if Green was still a discussion in different
industries and industry leaders or has Green fatigue set in ?
Less than a decade ago carbon credits were a boardroom discussion and
some people made a lot of money trading them; then they just vanished. Data
Centers started touting Power Usage Effectiveness (PUE) or Data Center
Infrastructure Efficiency to demonstrate how Green they were. Overhead
non-compute power usage for cooling and other uses ranged from typical 80% to
highly efficient 10%. Power used by servers and computers for the same task has
been reducing almost linearly over time challenging PUE.
CIOs finished fixing the data center quite early and also created
efficiency for end compute devices with power management policies and
improved awareness. From there on they focused energies on office
infrastructure, ambient lighting and temperatures, electronic documentation,
communication and as a result saved trees. A few also took control of energy
usage monitoring with embedded and targeted sensors linked to BMS (Building
Management Systems) and reduced power consumption in good measure.
The question is, with so much getting done and almost every enterprise
reaping the benefits over the last decade, is Green still a relevant discussion
? Who if anyone is tasked with overall enterprise Green initiatives ? Is it
only about controlling power used or creating a movement to conserve natural resources
? Is Green an integral part of decision making explicitly mentioned in
evaluation parameters or implicitly used in every decision making ? Have people
stopped flying around for meetings and embraced Video Conferencing ? The answer
is Yes and No.
I don’t believe that CIOs are measuring and reporting metrics around
Green. None of the CIOs I met did, but there is a discussion around power
efficiency and overall cost of running BAU or keeping the lights on. CXOs are
not enamored by earlier conventional solutions which are now basic hygiene as
are new LEED certified buildings. Reality is that for technology and compute
power, the bar keeps shifting every 4-5 years; what was green in 2000 or for
that matter even 5 years back appears archaic when compared to currently
available hardware.
At the conference the audience engaged in a discussion and debate on the
relevance, challenges and opportunities; one of the participants sought
suggestions to break the cultural vice around personal printers which gave his
global centurion company a person to printer ratio of close to one. Someone
shared extreme automation to switch off lights and air-conditioners when there
was no movement resulting in hilarious and occasionally dark and sweaty
situations while people were in the room working !
Green is here to stay and awareness of the new generation brings new
opportunities. For CIOs it is important to seek avenues beyond the conventional
interventions of the past. Cloud computing is shrinking the data center and
mobility is driving the workforce out of offices. Power generation is focusing
on renewable energy sources which reduce the global carbon footprint. Some of
the power hungry enterprises are going to embrace these as the world works
towards creating a better tomorrow.
The role you play in this evolution is up to you !
