Climate change and the energy crisis are forcing us to change our energy consumption in order to maintain a liveable planet. Unfortunately, the energy consumption of IT is growing exponentially, and so far, only a little has been done to curb it. To save the planet, software must also become more energy-efficient. One of the solutions is green coding.

Agenda

• The ICT carbon footprint and energy consumption
• How software consumes energy, generic model
• Measuring or lack of it
• Removing waste of energy from software
• Practical solutions
• Q&A and discussions
