Also IT is ecosustainable
Green computing or green IT is a term used to define the ecosustainable IT. It deals with the study and the design of eco-friendly IT tools and connection systems with sustainable environmental impacts to reduce the energy consumption and make the objects recyclable and biodegradable.
Consumptions connected to the use of computing devices are increasing. According to Greenpeace statistics data center and communication networks are going to consume around two trillion KWh of electricity in 2020, more than three times their current consumption. For this reason green IT has a double goal: to get good technological performance together with the energy efficiency.
To make a computer green minimizing the energy consumption is not enough, so this sector of IT studies the entire lifecycle of the devices from the project and production with low energy consumption and minimum environmental impact to the use and the disposal that has to include recycling.
The so-called electronic waste are about 23 tons a year and they include a large amount of heavy metals and plastic materials that are highly harmful to the environment. For example materials like arsenic and mercury should be deleted to promote the use of materials and components that can be recycled.
Now there are on the market ecologic computer, built with recyclable and biodegradable materials or respecting standards of energy efficiency, like those ones certified by Energy Star or TCO. Energy Star is an American certification recognizable by a blue logo with a white star and it identifies products with reduced energy consumption, while TSO is Swedish and certifies also the quality of materials used respecting the enviroment.
