Green IT aims to make information technologies more environmentally friendly by reducing energy consumption and the carbon footprint of digital infrastructures.
Best practices include data center optimization, electronic equipment recycling and eco-responsible software development.
Data centers represent about 1% of global electricity consumption. Adopting liquid immersion cooling techniques reduces energy consumption by 40-50% compared to traditional air cooling.
Sustainable IT takes into account the entire equipment lifecycle. Circular economy applied to IT hardware allows recovering up to 95% of precious metals contained in obsolete electronic components.
Software eco-design is becoming a discipline in its own right. By optimizing algorithms and application architecture, developers can reduce software energy consumption by 30-70% without compromising functionality.
Green cloud computing is developing rapidly. Main cloud providers are investing massively in renewable energy and already achieving carbon neutrality for their operations.
Digital sobriety is emerging as a guiding principle. Rather than simply optimizing the existing, this approach questions the real necessity of certain digital functionalities, promoting a more conscious and less resource-consuming usage.
