In Germany this year the market for smartphones grows faster than expected. Total revenues for 2015 increase by 7 per cent to 9.1 billion Euro (bitkom.org, 10.08.2015)
The total energy consumption of ICT is growing rapidly. Reduction of energy consumption is fine, but efficiency strategies alone have not led to a more sustainable situation. The following formula has been proposed for sustainable ICT
Efficiency + Sufficiency = Innovation for Sustainability (Hilty et al. 2011)
In mobile computing, the capacity of batteries in terms of energy density (energy/mass) is limited (DOI:10.5167/uzh-55640). This can be seen as an effective limitation (sufficiency), enabling more sustainable ICT innovations.
Besides energy consumption, scarce natural resources are part of every smartphone. The growing demand for mobile ICT devices results in an increase in product offerings, usually sustained through a shorter service life leading to a faster exchange of your smartphone.
Sufficiency strategies appear appealing to reach more sustainable consumption of ICT. Please share further examples of sustainable consumption of ICT, these can be driven by users, e.g. only use particular applications sundays, or driven by ICT design. I'm particularly interested in the interplay between user practices and ICT solutions for sustainability.
Are you aware of sufficiency strategies for sustainability in mobile ICT devices (like smartphones)?
