More Data, Less Energy: Making Network Standby More Efficient in Billions of Connected Devices

Introduction

The increasing digitalization of economies is driving significant growth in electricity demand. While data centers have garnered considerable attention, the energy demand from networked devices like smartphones, tablets, and set-top boxes is equally concerning. By 2050, the number of these devices could rise from 14 billion in 2013 to 500 billion, leading to substantial increases in both energy consumption and wasted energy.

Key Data Points

• 2013: 14 billion networked devices consumed 616 terawatt hours (TWh) of electricity, surpassing Canada's total electricity consumption.
• 2050: Projections suggest 500 billion devices could drive significant energy demand.
• Energy Consumption: Some devices, like game consoles, consume up to 80% of their energy just to maintain a network connection.

Energy Efficiency Opportunities

Implementing best available technologies could reduce the energy demand of network-enabled devices by up to 65%. However, without strong market drivers, policy intervention is necessary to optimize energy performance.

Role of the International Energy Agency (IEA)

Building on its experience in setting international policy for standby energy consumption of standalone devices, the IEA is addressing the larger challenge of network standby. The organization provides a framework for policy and technological solutions, identifying key stakeholders who should lead in specific areas.

Policy and Technology Solutions

• Policy Considerations: The IEA emphasizes the need for international cooperation across the entire ICT value chain.
• Technological Solutions: Various technical solutions are discussed, including optimizing networks for energy efficiency and implementing the IEA’s 1-watt standby plan.

Stakeholder Roles

• Policy Makers: Develop and implement energy efficiency policies.
• Standards Development Organizations: Set and enforce energy efficiency standards.
• Software and Hardware Developers: Integrate energy efficiency into device designs.
• Device Manufacturers: Ensure compliance with energy efficiency standards.
• Consumers: Encourage the adoption of energy-efficient devices.

Conclusion

Addressing the energy waste from network standby through existing technology and policy solutions could lead to significant energy savings. The rapid growth in connected devices underscores the urgent need for immediate policy action.

Summary

The increasing number of networked devices is driving significant energy demand, with some devices consuming large amounts of energy even in standby mode. Implementing advanced technologies and policy interventions can reduce this energy waste. The International Energy Agency (IEA) is working to address this issue by setting international standards and encouraging stakeholder participation.
