Policy Brief – The Wasted Energy of Connected Devices
Connecting devices to the internet has profound implications for energy use, in three areas: Digitalisation, Wasted Energy and Upstream Consequences. This policy brief covers the second topic
Policy Brief – Upstream Consequences from Connected Devices
Connecting devices to the internet has profound implications for energy use, in three areas: Digitalisation, Wasted Energy and Upstream Consequences. This policy brief covers the third topic
Domestic Air Conditioner Test Standards and Harmonization
This report is a comparative review of test procedures and efficiency metrics for room air conditioners across six countries, as well as the ISO standard. The findings of this report are intended to inform the efforts of policy makers to evaluate where greater consistency between test methods and metrics may be beneficial.
Huge energy-savings by WBG semiconductors
This is one of the latest articles published by the Swiss Federal Office of Energy (SFOE) related to wide bandgap technology, and its potential promising applications for SiC and GaN Semiconductors.
Policy Brief – The Role of Connected Devices in the Digitalisation of the Energy System
Connecting devices to the internet has profound implications for energy use, in three areas: Digitalisation, Wasted Energy and

Visual Perception under Energy-Efficient Light Sources – – Detection of the Stroboscopic Effect under Low Levels of SVM
Temporal light modulation (TLM, known colloquially as “flicker”) of light sources has visual, neurobiological, and performance and cognition effects on viewers.
Test Procedures for Measuring Network Standby Power
This paper examines elements of existing test procedures that address network standby in some way. This includes horizontal test procedures that cover standby and network standby for
Global Forecast of Energy Use for Wireless Charging
In this report, we have built on the modeling methodology published in a recent white paper by Natural Resources Defense Council (NRDC) and Suzanne Foster Porter of Kannah Consulting
Bridging the Network Standby Gap between Mobile and Mains-Powered Products
An integrated, energy-optimal design approach, in which disparate engineering teams collaborate iteratively toward energy optimization goals (including low network standby energy use), is currently the
Getting to Zero: An Evaluation of Zero Network Standby Power
This report examines the feasibility and economics of achieving network zero in three different products: mini-split HVAC systems, smart speakers, and connected light bulbs. We investigate the
Total Energy Model for Connected Devices
The objective of this study is to develop a quantitative model of the “total energy use” of connected devices, globally. This report (and model) aims to quantify the total additional energy that results from devices becoming connected to a communications network
Intelligent Efficiency for Data Centres and Wide Area Networks
This report discusses the energy consumption of data centres (DC) and the wide area network (WAN) which connects computers and other devices together on the internet. These are complex
