2. The digital revolution
New media, twitter, search machines and social networks
Every day there are three billion searches on google.com alone
This equals the daily electrity consumption of 110,000 EU households
Green use of our resources espc. energy in a global economy
Energy efficiency is one of the leading criteria for optimizing equipment and processes today
Data centers are the basis for today‘s communication
Green use of energy in data centers has become key differentiator

3. New media and social networks
Drive data center growth
Tools like smart phones and tablets in combination with global social networks open for interactions in all business and private life.
Network providers estimate for 2010 to 2015
Global internet traffic will increase 8times*
Mobile data traffic will increase 40times*
Data servers and fast optical data transmission are the back bone of such intensive information exchange. A concentration of up to several 1000th of servers in one spot give a good economy of scale.
Investments in huge centralized data centers (up to 90 MW)

4. Need for energy efficient data centers
Life cycle cost are mainly influenced by data center running cost as power consumption and maintenance cost.
Energy cost are exceeding the initial data center investment cost by 5times during life time*.
High density of electronics in servers are requiring heavy cooling with air and in hot spots with water even.
Large data center installations are located in low temperature regions like Scandinavia or/and close to bigger water reservoirs (sea).
Locations for data centers are not selected on where data are needed but on where energy is available and on security matters.
