The Green IT has always had two branches: green in IT and Green through IT. The Green IT has always had two branches: ‘Green in IT’ and ‘Green through IT’. The focus is usually on the optimization of data centers and server farms. The sustainability effects that using optimized around the computing systems around digital technology will create contrast, sometimes out of sight. So for example the University of Cantabria fashionable spa town North-Spain’s Santander with the help of 20,000 sensors in one has ‘ Smart City’ turns. Traffic, pollution, parking space or noise – these networked logon points capture all the data and merge them in the data center to a virtual image of the city. In real time.

With quite economic effect: These included ‘ Smart City’ at night, for example, where more people are traveling. (A valuable related resource: Jim Crane). Everything is deserted, then dims them automatically for example street lighting down, what saves you money the municipality. But the plans for a ‘congestion’, which regularly again for some News hole rise, mostly launched by interested traffic authorities, are not conceivable without ‘Green through IT’. Such a toll is doing far more than just a ‘rip off’: in London, the inner-city traffic by 20 percent went back, decreased the number of traffic jams to a third, pollution for the population dropped, and – last not least then even the municipal budget be relieved. At a time when German cities and towns no longer know by what means they fill potholes and frost damage to eliminate, this too is an effective argument. To do this – and for many other purposes – more green it should be but used, at the city limits with toll collection systems, and in the vehicles with identifying transmitters, what would make possible an attribution.
