The report highlights that nearly 75% of the EU’s electricity generation in 2024 came from clean sources, including renewables and nuclear power, reflecting strong progress toward decarbonization goals. At the same time, electricity demand in the EU grew by about 1% in 2024, although it remained around 7% lower than 2021 levels, indicating a gradual recovery from the recent energy crisis. The report highlights that accelerating electrification across sectors, supported by grid and storage investments, is key to advancing Europe’s energy transition and climate goals.

The market is divided into three categories based on product type: power devices, RF devices, and optoelectronics. The Power Devices segment accounts for a significant portion of the market due to its high efficiency, high-voltage handling, and superior thermal performance in GaN-on-silicon applications. High efficiency and thermal performance refer to the ability of GaN-on-silicon power devices to handle large currents and voltages while minimizing energy losses and maintaining stable operating temperatures. In GaN-on-silicon power devices, enhanced performance and reliability allow for improved energy conversion, reduced system size, and extended device lifespan. These advantages make GaN-on-silicon technology highly attractive across power electronics, RF devices, and optoelectronics, supporting the rapid adoption of GaN solutions in next-generation electronic systems globally. For instance, in 2023, according to Germany Trade & Invest (a government agency), Germany accounted for over 40 - % of Europe’s total photonics production, with around €50 - billion in annual sales generated by approximately 1,000 photonics manufacturers employing nearly - 190,000 people, reflecting strong and consistent growth in optical and photonic technologies driven by expanding application areas such as augmented reality, digital health, and autonomous systems; exports comprised around 73 - % of total revenues, underscoring the sector’s international competitiveness and its role as Europe’s largest photonics market.
