Energy can also be saved through cloud computing, namely the principle of outsourcing the programs and functions of one’s own computer to service providers over the internet. It is also called sharing storage capacity with others. In this case, smaller devices, some purely mobile, are all that is required to handle large volumes of data.
Another idea is the joint use of purely virtual space. ‘Digital sharing’ is the way of putting it. New ideas and programmes for video conferences are presented here in order to prevent people from taking unnecessary flights and to be climate-friendly by shifting business meetings to their own desk. Energy can be saved by using a laptop instead of a large desktop computer at workplaces or in home offices. Because, laptop components are energy optimized, primarily to ensure that the battery lasts longer.
Bringing modern LCD monitors into the picture is also a better idea of Green IT. Because, traditional CRT monitors have particularly high energy consumption. A classic green IT tip is to abandon the power-guzzling stand-by mode. We now have a range of different electrical sockets with on-off switches that should be deployed when using electronic devices for longer periods.
IT Managers can monitor energy requirements and can cap power usage and place servers in power saving mode with server power management. We can also apply green storage technique. For example, instead of running database that requires 5000 IOPS on 250 disk drives, put the heaviest hit portions of that database on a pair of mirrored and protected solid states disks.The rest of the data can use a smaller number of traditional fast disks while backups can go to high capacity SATA drives.
Enterprise desktop power management software automatically places monitors and computers into low power modes-sleep or hibernation.Using blanking panel in the data center infrastructure is another example of green IT. Going paperless plays an important role in green IT. Using more papers to print documents requires additional power consumption and ink of printers which creates additional cost and also it has significant impact on earth.Because,in order to produce papers, paper industries require massive power consumption and emission of greenhouse gas. So, reducing the use of paper and increasing the use of soft copy for documentation can contribute developing Green IT significantly.
