Green It
Some figures about IT and the environment
- Electronic devices and other IT related activity represent 4% of the total global carbon footprint, a figure that is growing every year due to sector growth.
- If the proportion may look small, it actually is important regarding other industry sectors; automobile sector, known for its pollution side effects, in its whole is for example estimated weighting roughly 6 to 9% of global carbon emissions. The entiere plane fleet is 2%.
- A computer (laptop or desktop) will during the course of its life emit a bit less than 100kg of CO2 eq. per year, cost which is between 70-90% manufacturing carbon footprint and the remaining in electricity costs.
- Among e-waste, monitors represent a significant volume. E-waste is difficult to recycle, and may under some circumstances become an environmental hazard.
Misconceptions around green IT
Latest model efficiency compensates for replamement
This is trivially wrong based on the above facts. Even 10 years ago, e-devices were for most part energetically sober. However, their manufacturing and disposal are polluting processes. +About

Latest model efficiency compensates for replacement
This is trivially wrong based on the above facts. Even 10 years ago, e-devices were for most part energetically sober. However, their manufacturing and disposal are polluting processes. Besides, unlike it could be the case for a car, having more efficiency at hand does not necessarily result in less consumption. If anything, more powerful model create new uses, creating more consumption.
Some programming languages are less green than others
Some people pointed out because Python is several tenths times less efficient than C, it is thenth times less green than C. While not completely wrong, this is simplistic, because only measuring runtime power consumption. Programs written in Python could take less time to write, thus possibly compensating. Resources on server side are rarely optimised below a certain threshold, so if two programs take one same vps instance, they are polluting the same. diff --git a/public/posts/index.xml b/public/posts/index.xml index 8cc988a..52268d3 100644 --- a/public/posts/index.xml +++ b/public/posts/index.xml @@ -6,7 +6,7 @@
