Energy reinforced internet

The Internet is by no means virtual and the cloud is not located in the sky, but in data centers on the floor, which only need between 6 and 12 percent of the energy consumed for calculations – the rest is security

Fruher has already been the production of computers and their energy and resource consumption, but the Internet and the conversion to eCommerce was still considered to reduce energy and resource consumption and thus also contribute to climate protection. The energy consumption through the Internet itself was considered negligible because the Internet largely use the already existing infrastructure and computer and peripheral devices became more energy-efficient, but teleworking and teleshopping could save a lot of energy in traffic and buildings in buildings.

However, it was already warned that the energy consumption could grow quickly, and in 2001, it was already suspected that the collapse of electricity grids in California could also be accessed on the Internet (electricity crisis in California). But it is clear that the server farms consume a growing portion of the electricity and by no means "clean" is.

The power consumption for the world-installed servers had already doubled between 2000 and 2005. However, only 14 power plants with a capacity of 1000 MW were still necessary for their operation, as the mobile network and the clouds were still in the starting pages (the internalization of the servers). By 2010, electricity consumption increased more than 50 percent, less than expected. Server farms spent in 2010 after estimates by 1.2 percent throughout electricity (server on austerity price). In the last report, Greenpeace mainly criticized Apple, Microsoft and Amazon because they operate their cloud data centers with electricity from coal and nuclear power plants.

Apple’s iCloud recreates 55 percent of the electricity of coal-fired power plants and 28 percent from AKWS. Amazon also consumes Greenpeace more than 60 percent electricity from the two energy sources, on Facebook it is more than 50 percent. The proportion of coal flow is at Oracle, HP and IBM with nearly 50 percent most highest. So the server farms not only consume a lot of electricity, sometimes as much as 180.000 single house, it is also often "dirty". According to Greenpeace, 2007 was the global electricity consumption of cloud computing, it is calculated as a country, with 623 billion kWh so high that it was fold to the US, China, Russia and Japan and before India or Germany.

The New York Times has now looked at the data centers again and concludes that most of the much energy is pushing, sometimes up to 90 percent of the electricity you get from the network. In addition, they ranging from security many diesel generators that can be produced according to CO2, and keep them in readiness. So in California, many data centers are listed on the toxic air constant inventory. In addition to the generators, thousands of batteries, mostly lead batteries, are often provided to can compensate for short power traces. And the servers will not only be faster and faster, even the storage space growth.

The New York Stock Exchange Hauft Daily 2.000 Gigabytes stored for years. Most of the 1.8 trillion gigabytes of data generated after estimates last year are derived from the individual users who collect and store enormous data volumes in the data rush, driven by the competing companies that propagate cloud computing. Worldwide, the estimation of the McKinsey research on the NYT commissioned by the NYT Company, consume the data centers 30 billion watts, about as much as 30 AKWs produce electricity. One third until a quarter is consumed in the USA.

Just once between 6 to 12 percent of the electricity of servers is actually used for calculations, the coarse part goes on it to keep the servers ready for an increase in traffic that could slow down or let the servers abandon. For the study were 20.000 Server investigated in 70 coarse commercial and state data centers. Overall, there should be more than 3 million data centers worldwide. The enormous waste of energy is largely owed to one "Symbiotic relationship between users who expect an immediate response to a mouse click, and companies that risk their survival if they do not meet this expectation", This is explained.

Although some companies such as Facebook or Google use new software and kuhl systems to reduce energy consumption, but Google’s data centers still consume 300 million watts and Watts from Facebook. However, most companies have become zogers and continue to waste energy. Accurate information is not available, but often the data centers are hidden because you do not like to reveal, just in an industry, so suffisan the NYT, the "To coarse part of access to personal data" is aligned. Not even the US government can capture how much electricity eat their own data centers. And that should be between 1998 from 432 to 2.094 have increased in 2010.

Cloud computing simply means that the computing power elsewhere, in a data center with many servers takes place somewhere in the world. It could be so suspected Randall Victora from the University of Minnesota that the internet users do not realize this shift. The Internet seems to be intangible and virtual, but if you save data in the cloud and does not require local storage space, it simply wanders in the cloud, but we can not do that in contrast to memory space on our computers, tablets or smartphones anymore realize. Data will transfer quickly, but the Internet is by no means virtual and intangible. That was just a myth.
