+===== Energy Efficiency =====
-In the design and implementation of IoT devices and infrastructures, balancing various design criteria is critical to achieving optimal performance while minimizing environmental impact. The concept of Green IoT (G-IoT) emphasizes designing IoT systems that are energy-efficient, sustainable, and environmentally friendly, addressing the growing concern about the ecological footprint of IoT technologies. However, achieving these goals often involves tradeoffs between competing priorities such as energy consumption, performance, security, cost, and sustainability.
+One of the primary design goals of IoT is minimising energy consumption, as many IoT devices rely on limited-capacity batteries. Energy-efficient hardware components, software optimisations, and low-power communication protocols are widely adopted to prolong device operating lifetimes. For example:
