Énergie

In computer science, „Énergie“ (French for „energy“) typically refers to the concept of energy consumption and efficiency in computing systems. This encompasses how much energy hardware components (such as processors, memory, and storage devices) consume during operation, as well as the overall energy use of software processes.

Energy efficiency is critical in various domains, including mobile computing, data centers, and cloud computing, where reducing power consumption can lead to lower operational costs and a smaller environmental footprint. Techniques such as dynamic voltage and frequency scaling (DVFS), energy-aware algorithms, and the use of energy-efficient hardware are commonly employed to optimize energy usage in systems.

Moreover, energy considerations are increasingly important in the context of sustainability, where the aim is to minimize the adverse environmental impacts of technology. This has led to the exploration of renewable energy sources for powering computing infrastructures and the development of certifications and guidelines for energy-efficient computing practices.
