The Green Information Technology (Green IT)

The Green Information Technology (Green IT) is a way to save energy and make better use of all information technology services, such as data centers, software services, communications, and their power supply.
Data Center
Each year, organizations spend a lot of money on purchasing a server for their organizations, while can be reduced by up to 75% using virtualization technology.

The basis of this technology is based on the use of a server device and the installation of several operating systems that work in parallel. In this way, there are many software solutions that Microsoft and VMware companies are among the pioneers of this technology and offer a variety of software in this regard. One of these solutions is the reduction in the power of the servers based on their needs. On each server, you need to be careful about how much server performance, equipment is projected and designed to fit the power supply. When the server is not used, such as nights and holidays, we minimize the amount of power it consumes. By doing this, the power consumption will decrease up to 50% per year. The cooling systems in data centers are also one of the most energy-consuming appliances. Proper design of the cooling system can, in addition to being more effective, reduce the energy consumption up to 25%.

Personal Computers
Personal computers in offices are one of the most used equipment, which consumes about 40% of electricity in organizations and offices. By implementing some software changes in their use, they can significantly reduce power consumption. For example, in many cases when users are not behind their computers, the computer is active and useless, which uses Hibernate software to detect system idleness and restarts if needed. The use of low-power components for systems is one of the other ways in which the service terminal solutions can be mentioned. This service is powered by equipment called Thin Client and MiniPC, which reduces at least 70 percent of the power consumption by this method.

Active network equipment
These equipment are used more in the network infrastructure; it has been observed that in many organizations there is a surplus of equipment purchased on the basis of the service’s demand, which also results in higher costs due to the fact that more energy-consuming equipment consumes more energy.
And as a result, more funding has been paid for equipment. In the same vein, manufacturers of the company, active equipment of the network have also produced low-power models of this device, which can be used at a lower cost, to provide these devices and to reduce the cost of energy consumed.

Inactive equipment of the network
The implementation of inactive network infrastructure in any organization is one of the most costly IT-related executive initiatives that normally require reconstruction and renovation every few years.
There are a number of ways to reduce costs and reduce the cost of maintaining this platform:
- Use of modular equipment
- Use of Trunking and Continuous Systems
- Use of blind replaceable optical fiber substrates

Electronic components, batteries, toners, and hardware equipment used in the IT field are known to be one of the most hazardous waste after nuclear waste after their life has ended, and if they are released in the environment, they will be irreparable damage. It is expected that the green information technology will be provided to the environment where after the end of the life of the IT equipment, the manufacturer of the equipment will return it to the cycle and safe disposal method.

Green information technology is a four-dimensional approach:
- Green approach in the green technology service provider can be found in the green office guide.
- The green approach in energy efficiency and energy saving and the optimal use of all services Information technology (such as data centers-and …)
- The extent of software impact in the green approach
- Waste management in information technology
