Le 'nuvole' ed i sistemi wireless sono un pericolo non solo per la salute ma anche per l'ambiente: la CO2 !!!

Questi studi condotti in Australia da Università, Governo dello Stato Vittoria,  ed industria evidenziano  come andando con l'attuale trend di crescita di utilizzo  tramite wireless di cloud (nuvole) per depositare dati, si ottiene un pericoloso e fortissimo incremento della produzione di anidride carbonica.

Con l'attuale trend l'aumento di produzione di CO2 dal 2012 al 2015 è equivalente  a mettere sulla strada altre 4,9 MILIONI di automobili !!!
Questo è dovuto alla estrema inefficienza della tecnologia wireless a trasmettere dati.


 

STUDY FINDS WIRELESS SYSTEMS ARE EXPECTED TO GENERATE ADVERSE ENVIRONMENTAL IMPACTS--equivalent of adding 4.9 million cars to the roads in CO2
THE POWER OF WIRELESS CLOUD; An analysis of the energy consumption, Australian Center for Energy-Efficient Telecommunications (CEET), 2013

"Our energy calculations show that by 2015, wireless cloud
will consume up to 43 TWh, compared to only 9.2 TWh in
2012, an increase of 460%. This is an increase in carbon
footprint from 6 megatonnes of CO2 in 2012 to up to 30
megatonnes of CO2 in 2015, the equivalent of adding 4.9
million cars to the roads. Up to 90% of this consumption is
attributable to wireless access network technologies, data
centres account for only 9%."
Wireless networks will use about 90 percent of the energy needed to power the entire wireless cloud services ecosystem in 2015, in contrast with data centers, accounting for nine percent—or less.
CEET is a partnership between the University of Melbourne, Alcatel-Lucent and the Victorian State Government. Alcatel-Lucent, through its research arm Bell Labs, and the University of Melbourne share governance of the centre. CEET aims to minimize network energy consumption.
Toni Stein note:
This study finds measurable energy losses from wireless systems. In the context of current energy supplies, this translates into expected significant CO2 emissions in the earth’s atmosphere that may significantly impact global warming impacts. There is accepted support and significant concern for GLOBAL WARMING’s adverse environmental health impacts including acceptance that UV radiation causes melanoma and cataracts from the UV radiation that is in the same electromagnetic spectrum.
KEY FINDINGS IN THE REPORT:
1. There is an emerging convergence and trend towards cloud services being accessed via wireless communication networks such as WiFi and 4G LTE.
2. The total energy consumption of cloud services accessed via wireless networks could reach between 32 TWh and 43 TWh by 2015. In 2012, the figure was closer to 9.2 TWh.
3. Wireless access network technologies account for 90% of total wireless cloud energy consumption. Data centres account for only about 9%. The energy consumption of wireless user devices is negligible.
4. Previous analysis and current debate on making cloud services more energy efficient is misplaced on data centres and ignores the massive impact of wireless cloud growth.
5. Industry must focus efforts on making cloud services more energy-efficient, including developing more energy-efficient wireless access network technologies.
