This analysis reveals router energy demand and its contributions to global electricity consumption, suggesting effective reduction strategies.
Reducing our society's energy demand is critical to address the sustainability challenge. While the Internet currently accounts for 1–-1.5% of global electricity consumption and continues to grow, the energy demands of one of its core components---routers---remain poorly understood. The available power data is limited and not fine-grained enough, offering little actionable insight into strategies for effectively reducing the Internet's energy consumption.
