ePowerSaver - A Computer Power Saving Solution for Your Organization

According to the Energy Information Administration, commercial electricity rates have increased almost 12% since 2005, and at many companies, I.T. is a major contributor to the power bill.

Statistics shown that data centres account for about 2% of the total electricity consumption in the United States, while PCs and office equipments account for another 5%.  Thus, when looking for places to save energy, desktop computers are an obvious and easy target.  Yes, we're talking about your desktop computer.

The US Environmental Protection Agency(EPA) estimates that no more than 10% of all PCs in use by organizations have power management enabled.  To make it worse, computers in most organizations have been left on 24/7 for various justifiable reasons!

Whatever the reason is to keep it on, your desktop computer will consume power.   Our tests and internet researches both shown that an average desktop PC uses roughly 130 watts of power when on idle.   Whilst a LCD monitor average consumes around 30 watts on idle.   For those who are still using CRT monitors, it'll consume around 70 watts of power on idle!   By simply leave the computer on 24/7, we are effectively wasting large amounts of electricity and contributing to greenhouse gases while we are sleeping.

As a matter of fact, over the course of a year around 70% of your computer power bill is paid for weekends and over the nights when your desktop computer is idle, doing nothing.

FACTS: An idle computer wasted average 798 KWh of eletricity over a year! The sum of the greenhouse gas emissions is equivalent to:

  • 573 Kg (1,263 pounds) of carbon dioxide(CO2) equivalent
  • Carbon sequestered by 14.7 tree seedlings grown for 10 years
  • Carbon sequestered by 0.13 acres of pine or fir forests
  • $148 power bill at rate of A$0.15 per KWh

The WISePowerScheduler has following main features:

  • Configurable Weekly Schduler, Daily Schduler, Ad Hoc Schduler and Special Event Constraints
  • Scheduler for computer monitor power lever control - Off/On/Low Power Mode
  • Scheduler for computer power lever control - Hibernation and Resume Power Level
  • Scheduler for computer power lever control - Standby and Resume Power Level
  • Scheduling the execution of specified programs
  • Automatically log current user out at specified time
  • Shut down and reboot computer at specified time
  • Scheduling to send Wake on LAN request to specified computer
  • Computer energy consumption monitoring(working in progress)

The ePowerSaver consists of following components:

  • WISePowerScheduler
  • Console Application & Demo[free].  It can be download from here
  • UI to manage the WISePowerScheduler
  • Monitor Power Management Console Application
  • WakeOnLAN Console Application

For various practical reasons, the computer power management features have not been enabled and desktop computers have been leaved on 24/7:

  • It might take up to 2 min. to turn computer power back on from power off or hibernation mode; and it's not only inconvenient but also a waste of productivity
  • In some organizations, it is required to keep the computer on so IT ops can release service patches, client applications etc.
  • Sometimes you simply forget to turn the desktop computer off before going home, every now and then

We see the need to automate computer power management to make our life easier and reduce our greehouse foot prints at the same time.

Wouldn't it be nice if we could make our computer smart enough to turn itself off when it's not being used and turn itself back on just before it is needed?

Our engineers at the WANG Infonology Systems are listening; and here is our solution to your call - ePowerSaver!   It is a suite of software applications build based on our core component - WISePowerScheduler.

It has been designed as such that it is able to switch computer power level from normal to standby, hibernation; and switch back to normal power level from hibernation and standby.   It can be configured to hibernate computer to save power after you left office for the day; and automatically switch computer power level back to normal level before you come to the office next morning.   Best of all, there is no need to make any change to your computer hardware and configuration.   All you need to to launch this configurable application at start up from login script, or batch file. Alternatively, install it as a Windows Service.   Once launched, it is all automatically managed by a build-in MasterScheduler(Server Version only), DesktopScheduler, and Special Events Scheduler.   Easy, isn't it?

Let's say an employee works 10 hrs a day in your organization, which means computer will be idle for 14 hrs a day over night.   In one week, computer will be idle for 118 hours:

  14hr x 5 days + 24hr x 2 day weekend = 118 hrs.

In one year, a computer will be idle for 6136 hours, which means 70% of the time the computer has been on idle:

hours computer is idle over a year : 118 hr/pw x 52 weeks = 6136 hours

% of idle time over a year: 6136 hours idle per year / (24 hours x 365 days) = 70%

If a computer consumes 130 watts of power. Over a year, it consumes 798 KWh:

6136hr x 130Watts / 1000 = 798 KWh

Let's say the electricity rate is $0.15 KWh, over a year the computer power bill will be around $120:

798 KWh x $0.15 = $119.70

For an idle LCD, the power bill will be around $28:

30 watts x 6136 hours idle for a year / 1000 = 184 KWh x $0.15 = $27.6

If the ePowerSave is used, the save for an average computer over a year will be around $148.

$120 saving for computer + $28 saving for LCD = $148

The sum of the greenhouse gas emissions for 798 KWh wasted by a computer is equivalent to:

  • 573 Kg(1,263 pounds) of carbon dioxide(CO2) equivalent
  • 65.1 gallons of gasoline consumed
  • 1.3 barrels of oil consumed
  • 14.7 tree seedlings grown for 10 years
  • 0.13 acres of pine or fir forests
  • recycling 0.2 tons of waste instead of sending it to the landfill
  • $148 power bill at rate of $0.15 per KWh

For an organization which hundreds or thousands of computers, the saving will be huge! As for example, if your organization has 1,000 computers, over a year it will be saving you $148,000.

In addition to the saving of your energy bill, the ePowerSaver solution will reduce your greenhouse footprint and saving the environment.

An idle computer wasting average 798 KWh of eletricity over a year - That´s a surprising amount of power!

Based on the figured provided by EPA, the energy wasted is equivalent to 573 kilograms of carbon dioxide (CO2) emitted into the atmosphere for the majority of Australian consumers whose power is sourced from coal power plants.

It is estimated that for an organization with typical 1,000-PC environment, it can save A$148,000 annually by applying the ePowerSaver solution and activating power management, which would reduce power use by 798,000 kWh -- enough electricity to light 80 homes annually. From a greenhouse gas perspective, it reduces gas emissions by 573 tons, or the annual emissions of 105 passenger cars.

FACTS:The annual sum of the greenhouse gas emissions by 1,000 idle PC are equivalent to:

  • 573 Tons (1,263,457 pounds) of carbon dioxide(CO2) equivalent
  • CO2 emissions from 65,050 gallons of gasoline consumed
  • CO2 emissions from 1,333 barrels of oil consumed
  • CO2 emissions from the electricity use of 79.5 homes for one year
  • Annual greenhouse gas emissions from 105 passenger vehicles
  • Carbon sequestered by 14,695 tree seedlings grown for 10 years
  • Carbon sequestered by 130 acres of pine or fir forests
  • 798,000 KWh of eletricity wasted annually
  • A$148,000 power bill at cost of A$0.15 per KWh
