Energy efficiency is not a new trend in the electronics industry. However, demands are growing, driven by rising electricity prices, regulatory pressure, as well as the increasing need for energy-efficient components for systems, power electronics, and IoT devices. From 10-13 November 2026, the international electronics industry will gather at electronica to discuss the latest trends in energy efficiency.
The debate over energy efficiency now encompasses the entire electronics value chain. It ranges from semiconductors, power supply and embedded systems to electromechanics and industrial connection technology. The question of how best to achieve energy efficiency is a recurring theme across nearly all application areas, from consumer electronics and automotive electronics to industrial systems and devices.
As the world’s leading trade fair and conference for electronics, electronica brings together companies from across the entire value chain to discuss technical challenges and current trends in using energy efficiently. “Energy efficiency is becoming a key requirement for the electronics industry. At electronica, it’s clear that efficient products are in demand today in virtually every sector—from electromechanics and automation to connected industrial applications,” says Caroline Pannier, Exhibition Director for electronica.
Energy costs are falling thanks to efficient electronics
Recent studies show that energy efficiency is becoming increasingly important across various industries. In the automotive sector, the IEA’s Global EV Outlook 2026 shows that electric mobility continues to gain momentum: in 2025, more than 20 million electric cars were sold worldwide, meaning that roughly one in four new cars sold is already electric. As a result of this trend, the demand for energy-efficient electronics is growing—from power electronics and charging infrastructure to battery technology.
A study by Fraunhofer IZM shows that modern technologies are improving energy efficiency. Because of this, the energy requirements of mobile networks will increase only moderately in the coming years despite rising data volumes. Energy efficiency is also becoming a greater focus in other sectors, such as electronics manufacturing. McKinsey concludes that it is possible to reduce energy costs for semiconductor factories by 20 to 30 percent through efficiency measures.
Energy efficiency often stems from the system
For the electronics industry, this means that energy efficiency is becoming a strategic factor both in the product itself and in the manufacturing process. This is particularly evident in the field of electromechanics. This field doesn’t just deal with individual components, but also with the way connectors, housings, cable routing and interfaces interact with each other.
Low contact resistance, robust connection technology, EMC-compliant design and maintenance-friendly systems reduce losses, enhance operational reliability and simplify maintenance. The focus is therefore increasingly shifting toward the system as a whole, which has to be designed to be energy-efficient in order to conserve energy directly at the source.
electronica provides a platform for efficient electromechanics
electronica covers the entire electronics value chain, which is the reason for the focus on electromechanics. Exhibitors such as Harting, Phoenix Contact and Weidmüller will be showcasing connectors, relays, switches and enclosure technology, among other products. Harting, for example, specialises in industrial connectivity solutions for the transmission of data, signals and power, and focuses on applications in the fields of electric mobility, renewable energy, automation and mechanical engineering.
Phoenix Contact also demonstrates that energy efficiency begins right at the electromechanical level, for example, in connectors, terminals, enclosures, power supplies and interface solutions for electrification and automation. Weidmüller’s product portfolio includes the likes of terminal blocks, connectors, PCB connectors and other components for the safe transmission of power, signals and data. Meanwhile, the distributor Arrow Electronics, together with its partners, focuses on electromechanical components and high-performance passive components, which are designed to improve energy storage and efficiency and reduce losses in applications such as electric mobility, renewable energy systems and industrial automation.
This clearly demonstrates that any visitors looking for energy efficiency at electronica will find it not only in semiconductors and power electronics, but also in the field of electromechanics.
At electronica 2026, around 3,500 exhibitors from some 60 countries will showcase their latest solutions for the All Electric Society. Topics such as energy efficiency, automation and the circular economy will also be addressed in the supporting programme and in the forums, where participants will discuss technological developments, regulatory issues and sustainable concepts for the future.
