Have you ever thought about the huge power consumption of mobile phone base stations?
Example from Denmark: Power consumption, basestations and phone battery-chargers 2008-2009:
- 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) . Sources for calculation: 1, 2, 3.
Several nuclear plants (like the unfortunate Fukushima in the picture) are currently needed in the world to provide electricity for base stations and mobile phone chargers. (An "average" nuclear power plant generates about 12.3 billion kilowatt-hours (kWh) in a year).
Hey! It's peanuts to switch off especially healthy lights compared to the switching of mobile phones and base stations.
My Wish to You: During the Earth Hour do not switch off any lights.
