What is IT2Green?
This video gives an overview about the technology program IT2Green. With the help of a contest ten initiatives developing energy efficient solutions in the sectors “Telecommunication Networks”, “Computing Centres and Clouds” as well as “Monitoring and Management” have been selected. The main addressees of the initiative are medium-sized enterprises in public administration and in the area of housing and living.
Projectfilm MIGRATE!: Saving energy with the cloud
Traveling by plane has become more comfortable over time. However, we barely ever recognize that a large amount of data, from different places, is generated in the background while checking in, boarding our luggage, at the baggage claim or boarding. Processing this data is progressing with huge deviations and energy consumption is highly variable during these processes as well. For that reason ICT infrastructures are used in a highly inefficient way. The movie of the project MIGRATE! demonstrates how the project partners realise increases in efficiency of complex ICT-processes at the Stuttgart airport with the help of cloud-computing. No doubt: compared to ordinary technologies the energy efficiency is clearly higher when using cloud-computing.
Projectfilm IntelliSpektrum
How to set a cell tower into stand-by mode so that it only consumes energy when needed? The video of the IT2Green project IntelliSpektrum informs about the requirements and prerequisites for establishing a flexible and hierarchic radio network structure in mobile communications. In case the mobile network is currently consisting of larger radio cells which are constantly consuming the same amount of energy regardless of the actual network usage, IntelliSpektrum analyzes how the highly variable network usage and the resulting inefficiencies in energy consumption can be overcome with radio cells of different sizes (macro, metro, pico, femto). .
Projectfilm Pinta: Smartphones are taking control
With smartphones as intelligent control units, electric devices in offices could consume less resources with smart on demand energy consumption that allows enabling and disabling devices as required. This is the main and fundamental idea of the project Pinta, which is introduced in this movie. Pinta controls offices in the way that their energy consumption is decreased. While doing so Pinta recognizes user preferences and manages electric devices in homes in an adequately adjusted manner. Existing devices and sensors offer an infrastructure that can be controlled by smartphones.
Projectfilm Government Green Cloud Laboratory
The Government Green Cloud Laboratory’s video vividly shows how a cross-regional, intelligent network can provide a flexible computing capacity that can be used on demand and in areas that obtain their electric power from renewable energies in a sufficient amount or are situated in areas that are, due to weather conditions, predestined for an energy efficient usage of IT resources.
Projectfilm DESI: Intelligent supply and consumption of energy
The Telekom’s communication network covers 9,000 energy storages that were supposed to guarantee emergency supply of the network. Today these storages can be integrated into an intelligent energy network (Smart Grid) in order to compensate for unstable energy supply. This can, for example, be done with the help of wind power stations that are used to stabilize the overall energy supply. The movie of the IT2Green project DESI demonstrates how scientists research and formulate the requirements for an efficient way of dealing with this challenge.
Projectfilm AC4DC
Unused active capacities are the reason for high energy consumption of isolated, optimized standalone systems in ICT. This aspect is the crucial point to look after when trying to reduce system’s inefficiencies. The project AC4DC begins with this observation in order to let companies consisting of users, hardware, computing centres, data networks and energy providers optimize their energy and cost efficiency.
Projectfilm ComGreen
Not every user of a mobile communication device needs to have the maximum bandwidth at any time and any place. The optimization of radio networks, a system to adapt capacities and improve the usage of hardware, is one of the main research interests of the ComGreen project. Basis for their studies is the self-organised, context based adaption of a network's operating parameters in a way that the best possible differentiation between energy demand an efficiency factor can be achieved.
Projectfilm Adaptive Sense
With the help of a sensory network that knows the status of each user, software application and the corresponding IT environment (devices, hardware and network) the IT2Green project Adaptive Sense researches how these statuses within a network can be estimated and electric data processing can be adjusted to the available resources. This way a large sum of electric and thermal energy can be saved which consequently increases the energy efficiency of ICT systems in an significant manner.
Projectfilm GreenPAD
Developing, testing and transferring an optimal energy ICT infrastructure model for regional economy and science clusters is the main goal of the project GreenPAD. They bundle ICT infrastructures of regional areas so that the combination acts in the manner of a large computing centre. Consequently GreenPAD reduces the overall demand for energy of the ICT infrastructure of that area.
