A smartphone uses more power than a fridge!

[Christophe]

In overall energy balance, a smartphone consumes (rait?) More energy per year than your refrigerator! An American study has just shown it: http://bigbrowser.blog.lemonde.fr/2013/ ... igerateur/

(...) The document, which does not skimp on the comparisons, thus explains that an iPhone consumes more electricity than a refrigerator - 361 kiloWatt-hours per year on average, against 322 kW-h - taking into account energy needs of its battery, wifi, or downloads and data exchanges (the calculations do not take into account, conversely, the energy consumed to produce the food stored in its refrigerator).

More generally, ICT weighs, with 1 teraWatt-hours of electricity consumed per year, for 500% of world production. Or the production of Germany and Japan. Or, to put it another way, the electricity which made it possible to light up the whole planet in 10. "We already use 1985% more energy to circulate bytes than to move all the planes in the world", also reports the Time.

(...)

Thus, streaming a high definition movie over a wireless network consumes more than making and transporting a DVD of the same movie.

Today, 247 billion emails pass through the web every day. What energy allows it? Clean in appearance, the virtual world is actually as polluting as it is energy-consuming. If the Internet were a country, it would be the fifth largest consumer of electricity in the world. But its immense needs come up against the reduction in energy resources. Travel to datacenters, storage factories that operate day and night, nerve centers of the next war in the digital economy. Some large groups, such as Google or Apple, have responded by building new centers, using renewable energies. Could the Web be, on the contrary, at the origin of a third industrial revolution?

Excellent
it's pretty consistent
the future may have an impact on energy with these little devices

This analysis of "additional energy expenditure" may not be wrong, but short-sighted:

yes, a surge or a computer, or a smartphone connected to the internet consumes and makes consume "connected systems" but:

what if we had to travel to

- go get fresh food
- find that an order has not arrived or that a customer or a friend is absent
- go shopping to find (or not) any property
- go to the library, only for information
- go to the agency to book a plane ticket
- Etc. ..

not to mention saving time

I just read but I still find it hard to believe ... it seems so crazy ...
