The IT sector’s power demand is huge – and not recognised. Its emissions are the same as that of the global aviation industry. 25% of a building’s power demand can be from IT equipment, but because most IT equipment looks pretty much the same whether it is on or off, people tend to have a blind spot. Look at the graphic – this is a normal office – now look closely: There are 15 monitors visible – all are switched on – only 3 are being used. These figures are also confirmed in the smart 2020: enabling the low carbon economy in the information age http://www.transend.co.nz/sites/default/files/Smart2020Report_lo_res.pdf
Behavioural change can be very hard to achieve, but that does not mean it should be given a low priority. Ultimately, it is behavioural change that will defeat climate change, supported by technology. Unless peoples behaviour changes, simply having the ability to reduce power demand does not mean it will actually happen – think about that £2.8 billion being burnt every year in the US. An issue with changing behaviour is that group behaviour does not necessarily reflect what an individual believes their behaviour to be. The economically and environmentally rational choice is not always (or even often) the choice made by groups. There are many reasons for this, but part of it is that, environmentally, we pretty much always take the EASIEST route without too much regard for the consequences. If you look at behaviour change campaigns that happen in isolation, they will typically have a high initial impact, but behaviour slips back quite quickly as people slip back into old habits. There needs to be a means of making behaviour change easy and make it stick. It is VERY hard to make lasting change in energy use behaviour inside an organisation without support to make it easy for people So, lets look at the IT energy problem and ask the question…CAN WE MAKE IT EASY TO CHANGE?
http://www.transend.co.nz/sites/default/files/Why Power Schemes are not enough.pdf PC Insomnia occurs when a PC does not consistently transition to a lower power state due to application nuances, or spurious network, central processing unit (CPU) or disk activity. Some common causes of PC Insomnia include: Environment: Numerous services or agents within a PC image of an enterprise may spike the CPU utilization during periods of inactivity causing the Microsoft Windows® Idle Timer to reset. Custom Device Drivers: Device drivers not written to the Advanced Configuration & Power Interface (ACPI) specification may not allow the PC to enter lower power states. Screen Savers: Some intensive screen savers may require higher CPU utilization causing the Windows® Idle Timer to reset. Applications: Terminal emulation software, media players, and some custom-developed applications may not allow the system to enter a lower power state. System Configuration: Some PCs may not have their BIOS configured correctly to allow for system standby or the power state known as S3 or Sleep (ACPI specification). As a result of PC Insomnia, PCs stay on while not in use and subsequently waste energy and result in increased CO2 emissions. Some PC’s take a significant period of time (30 seconds or more) to return from a ‘ sleep’ state, and historically PCs have suffered many issues after returning from sleep (video glitches, network connectivity, slow response etc), requiring many operating system patches and firmware updates to address the issues. )There are over 50 ‘ sleep’ related Microsoft knowldge base articles relating to XP and over 100 for Vista).
30 tonnes CO2 is the equivalent of: • Carbon sequestered by 380 pine tree seedlings grown for 5 years (or 38 pine tree seedlings grown for 10 years, as they thin them at about age 6) • Carbon sequestered annually by 878 m2 of pine forests • Carbon stored in 473 m2 of New Zealand native forest preserved from deforestation
And again, we make it easy for the user. If you don’t have user buy-in, energy saving initiatives won’t work. So how do we make it easy for them? Users may be doing something the want the machine left on for – for example a complex risk modelling programme that takes several hours to run, or downloading a large file from the internet. The user needs to be able to override the system to allow overnight working when it is required. Some critical applications may be running on the machine that need to carry on running, so the system needs to be able to recognise this, and not switch off the machine until these processes are finished – for example, a system backup or maintenance such as installing software patches. Users work MUST be protected – shutting down and losing work will guarantee users will do anything they can to bypass the system, and will generate negative feelings to energy savings. NightWatchman avoids this by automatically saving open documents and data when it shuts down. So using NightWatchman causes the user no problems – it is a win-win scenario. The power management system saves the company energy and costs, users are not inconvenienced, and they also get to know they are saving energy without actually having to do anything.
1E invented the PC Power Management market 10 years ago and developed NightWatchman, the award-winning PC Power Management tool - as recognised by leading analysts, customers & media The NightWatchman PC Power Management system is a highly effective environmental management tool that requires no hardware upgrade and has an enviable track record of proven energy savings Typically, NightWatchman saves $35 and 200 kg CO2 per PC per year, with a return on investment in 6 months. (These are UK/US figures) NZ CO2 is much lower. It is a power management system that works in existing equipment – there is no requirement for expensive IT upgrade It is a tried and tested solution. With 4.5 million licenses, it is reducing the IT sector’s CO2 emissions by around 900,000 tonnes CO2 per year – and saving around $158 million in energy costs. To put this in context, this amount of CO2 is approximately 25% of the CO2 reduction the UK government is aiming for from the Carbon Reduction Commitment by 2020. So, it looks like we have a magic bullet – a real one, not a theoretical proposition.
