Brush off your calculator, this number is certainly going to make you cringe.. “ 1984 Tons of CO2 a year. “
If you leave your PC on AT night it will cost you money & contribute to your carbon footprint (NOT GOOD)!.
I’ve talked about power management for some time now & I’ve focused on the importance of power management, however what I have not talked about is the $$’s, #’s and the hard data. Let me use this opportunity to do so. After spending the last few months learning even more about power I would like to go after a few power data points (Power Points ) that I think are going to make you cringe.
First let’s look at how electricity is made worldwide - here’s a graph from - http://www.eia.doe.gov/oiaf/ieo/electricity.html showing worldwide electricity generation by fuel 2005-2030. Coal is of course the #1 source worldwide for electricity generation.
Now let’s peak into the US. On Wikipedia.org @ http://en.wikipedia.org/wiki/Electricity_generation
In the US – 48.9% of electricity is created by coal. At this point your probably wondering where I’m headed on this blog and what is my point.. well. If we know that coal worldwide is #1 and in the US it has 48.9% of generation source, then when we talk about not using electricity it should be a good thing ($$’s, eco friendly, etc..) So let’s model it out. !
First we need to lay out a few assumptions around what is a Managed PC & NON Managed PC.
• Here in this EPA presentation it discusses power cost comparison for both. http://eetd.lbl.gov/EA/Reports/39466/39466-2
• For this blog we are discussing a “Managed PC” and we are utilizing the energy star calculator located @ http://www.energystar.gov/ia/products/power_mgt/LowCarbonITSavingsCalc.xls
• Assuming a install base of 1000 well managed PC’s
What is the Output?
1000 well managed PC’s =
1,232,676, kWh of savings (CFO’s cringe)
1984 Tons of CO2 (Eco folks cringe here)
Now let’s make this specific by region on the US, if you utilize the following power rate’s - http://www.jea.com/services/electric/rates_quarterly.asp and since I’m headed to Florida I’ll utilize the current rate between $110-114/1000kwh, this equals $140k (Finance analyst take note –WOW
is the response I’m looking for. )
Now for certain regions of US the story ends here, however for power districts where coal is the source of electricity generation we move on to CO2. Taking an average passenger car which produces 5.2 Ton’s of CO2 per year (quoted from EPA Site http://www.epa.gov/OMS/climate/420f05004.htm#issue.). If you take that same 1000 PC’s that equals 1984 tons of CO2 a year, make them vPro, manage them, you can potentially put theequivalent of 400 cars off the road per year.
Sounds great right.. of course, now if you look at the 3 following case studies you will see more specific to Health & Education .
#1. Cleveland Clinic - http://communities.intel.com/openport/docs/DOC-1915
This article describes how Cleveland Clinic will achieve positive ROI of $442,000 in net power savings over 4 years and will also save 29,000 IT support man-hours in the same time period.
#2. University of Plymouth - http://communities.intel.com/openport/docs/DOC-2020
Recently, the University of Plymouth completed a refresh of their 4,800 desktop PCs, upgrading the systems to PCs with Intel® Core™2 processors with vPro™ technology in order to offer students the latest in IT services. The university was particularly interested in Intel® vPro™ technology because of the potential to allow intelligent power management, which could reduce power consumption and reduce the university’s carbon footprint.
The State of Indiana’s newly consolidated Indiana Office of Technology (IOT) conducted a manageability assessment of PCs with Intel® Core™2 processor with vPro™ technology1. Their decision to convert 20,000 desktop systems to PCs with Intel® vPro™ technology within four years was based on reduced operational expenses2. The challenge was the consolidation of several IT service groups serving different agencies into a centralized service delivery organization while improving customer service and decreasing support costs
vPro Managed PC = Lower costs for POWER = Reduce Carbon Footprint
Let’s take this to action now: 2 part story here, 1) what are the management consoles doing 2) what can you do with power software in the mix.
Scale out w/ the following power jobs:
What are the leading software vendors saying?
JamieK’s blog on vPro Expert Center - http://communities.intel.com/openport/blogs/proexpert/2008/06/03/intro-to-verdiem-and-pc-power-management
Verdiem web site http://www.verdiem.com/surveyor5/default.asp
A typical PC consumes nearly 600 kWh of electricity annually. SURVEYOR can help reduce that energy consumption by an average of 200 kilowatt-hours (kWh) per PC annually. In a PC-intensive organization, this typically represents a 3-6% annual reduction in total electricity consumption, saving an average of $20-$60 per PC annually. Additionally, by eliminating PC network energy waste, organizations also reduce associated CO2 greenhouse gas emissions.
1E doc on the climate savers site: http://www.climatesaverscomputing.org/docs/Energy_Report_US.pdf
Power management software can reduce a PC’s power consumption by 80 percent, allowing com¬panies to save between $25 - $75 per desktop PC.28 Beyond automated “shut down,” power savings are derived during the day by automating monitor shut-down after a period of inactivity.
At 8.68 cents per kWh, a typical PC left on overnight wastes $55.13 a year. That’s more than $165,000 for a 10,000-PC enterprise that leaves 60 percent of its machines on, and $1.72 billion for the 60 percent of work computers that may be running across the country each night unnecessarily.
So… why did I say “Don’t share this BLOG with your finance Analyst or your ECO team, they will not be happy! .. “ Well if you’re the last to know about vPro and you have it in your IT shop, that could be a fun conversation to have with your CIO & CFO. So. “don’t be the last to know about vPro”..
