This research study examines new battery technologies suited to powering small devices such as IoT, actuators and sensors, and portable devices such as mobile phones and laptops.
Smart lamps and luminaires are common in today’s lighting market. Smart lighting provides an opportunity for the consumer to benefit from wireless control of lighting products, e.g. by dimming, colour tuning and scheduling. These functions can provide energy saving but they also require energy consumption to supply standby power and gateways.
A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors
Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is widely researched, the relation to the energy use during manufacturing processes remains insufficiently studied. This question is especially relevant for Silicon carbide (SiC) semiconductors, as there are some […]
The report summarises the results of the EMSA Survey on the potential impact of digital technologies on electric motor driven systems in industrial companies.
This report describes updates to the Total Energy Model that was developed by EDNA to estimate the ‘total energy use’ of connected devices, globally.
Abstract: From cell phones to cars to data centers: The diverse electrical applications that visibly and invisibly shape our everyday life all contain switching elements made of semiconductor materials. These powerful electronic components have huge energy-savings potential that can be realized by using so-called wide-bandgap semiconductors. This is the conclusion of an expert report of […]
