Denemarken: Telecomindustrie verantwoordelijk voor grote uitstoot CO2.

woensdag, 16 december 2009 - Categorie: Berichten Internationaal

Zendmasten voor mobiele telefonie verbruiken per maand 2500 KWh. Met het verbruik van elektriciteit door het opladen van mobieltjes komt de totale consumptie per jaar neer op gemiddeld 51 KWh per persoon ofwel zo'n 25 kg CO2 per hoofd van de bevolking.
Op wereldschaal produceert de telecomindustrie omgerekend 101.363.845 ton CO2 en draagt daardoor wel degelijk in grote mate bij aan de opwarming van de aarde aldus een groep verontruste Deense ouders verenigd in vore brns fremtid (de toekomst van onze kinderen). De berekeningen zijn gebaseerd op gegevens ontleend aan onderzoek van Ericson en publicaties in het gerenommeerde ingenieurstijdschrift op eetimes.eu:

Mobile phone users of the world are causing a power consumption of more than an estimated 200.000.000.000 kilowatt hours (200 billion Kwh) which is roughly equal to 100 million tons of C02 emissions every year. Included in those figures are only the C02-footprint from mobile-phone usage (battery chargers etc.) and running the infrastructure of mobile-phone basestations. The power consumption of installing new basestations is not included.

These calculations have been done by the concerned parents group ''Our Children's Future'' in cooperation with the Danish company www.Feltfri.dk that specializes in measuring and screening of microwave fields from mobile-phone technology. The conclusions are supported by figures from the mobile-phone industry (see references below). The figures are estimated according to Danish conditions and extrapolated to global conditions from the latest available numbers of mobile-phone subscribers worldwide.

Power consumption, basestations and phone battery-chargers, Denmark, 2008-2009:

7.500 basestations in Denmark running 24/7 use 2500 Kwh per month, giving a total of 234.000.000 Kwh per year.
5.000.000 phone battery-chargers in Denmark (= no. of subscribers) use 0,3225 Kwh per month giving a total of 19.350.000 Kwh per year.

With a 253.350.000 Kwh total power consumption in Denmark, it amounts to a yearly personal power usage of 51 Kwh for every mobile-phone subscriber.

Extrapolated to a global scale of 4 billion mobile-phone subscribers, it gives a estimated total of 202.680.000.000 Kwh which corresponds to C02-emissions of 101.363.845 tons every year!
(one Kilowatt/hour of conventionally produced electricity corresponds to approx. 500 grams of C02)

Report on mobile-phone technology and C02-emissions:
In a recent (2006) report, Actix suggests that... worryingly, the report suggests that the mobile network energy consumption of an estimated 61 billion kWh worldwide, with each of the millions of basestations producing nearly 10 tonnes of carbon emission a year, will get much worse, and possibly double by 2011.

Ericsson: CO2-footprint per subscriber is 24-29 kg annually.

See table 3 for breakdown of subscriber CO2-footprint by technology:
GSM = 24 kg and 3G = 29 kg per year.
Using a weighted figure of 25 kg per year multiplied by 4.000.000.000 sbuscribers world-wide it amounts to 100.000.000 million tons of C02 per year (25 x 4.000.000.000 / 1000 = 100.000.000).
