Sustainable consumption: how to optimize the use of electronic devices?

TVs, computers, cell phones: the number of people using at least one electronic device (if not several) every day is always growing. But even though their purchasing prices have sensitively dropped down in the past years (especially if you compare the technological improvements implemented on these devices since a few years), it is often forgotten that their use also has a cost (which is not restricted to your monthly subscription).

A recent study has shown that charging and/or powering electric devices accounts for 11 percent of French home owners’ total electric consumption (over 2 billion euros, representing 86€ per year per home). Though part of that consumption is irreducible (especially when it comes to devices such as fridges), actually turning off some of our electrical devices (instead of just pushing an off button that puts them on standby) could become an eco-friendly habit we do not yet have.

In the meantime, forgetting to turn off our electrical devices could soon become profitable according to Quarnot Computing: this French start-up has engineered a new kind of computer that uses the heat it produces to power a radiator. The idea was to translate to the scale of a personal computer what has already been implemented in data centres, and prototypes will now be tested in public houses in Paris.
Could this be a way to insure our ecological transition by benefiting from the digital economy?
