As society accelerates its shift toward electrification in order to decarbonize energy systems and combat climate change, this green revolution hinges on our ability to optimize energy management. What role will power semiconductors play in this transformation? Can Europe turn this challenge into a lasting competitive advantage?

Europe has rare end-to-end capabilities in next-generation semiconductor materials such as synthetic diamonds, offering superior performance with lower environmental impact. This represents a convergence opportunity where industrial policy, climate targets, and technological sovereignty align, if approached strategically.

Semiconductors: the invisible champions of energy transformation

The term “semiconductor” often draws blank stares, and the critical challenges surrounding these components remain vastly underestimated. This disconnect isn’t surprising, as we’re dealing with an invisible technology that operates behind the scenes. Still, semiconductors are fundamental both to today’s society and to tomorrow’s sustainable future. A semiconductor refers to materials with specific physical properties that control the flow of electric current. They are essential to the manufacture of electronic circuits, photovoltaic cells and, more broadly, all the chips that control our digital objects, vehicles, and intelligent energy systems. Semiconductors are the key components that enable electronic chips to be high-performance, fast, and energy-efficient. Understanding semiconductors requires grasping two main categories:

? Conventional semiconductors allow our smartphones, computers, and everyday connected devices to operate, driving the digital world we navigate daily.

? Power semiconductors are engineered to handle high electrical currents and maximize energy efficiency in conversion, distribution, and protection systems, the workhorses of our energy infrastructure. As our daily lives become increasingly power-dependent, electricity has emerged as the new “precious” commodity. This reality requires optimal and responsible energy management at every level of consumption.

Semiconductors: where economic, geopolitical, and environmental forces converge

Power semiconductors are fundamental elements of modern power electronics, enabling the most efficient conversion, modulation, and control of electrical energy possible. By improving the equipment’s energy efficiency, they simultaneously reduce electricity consumption and lower operating costs.

Yet beyond their ubiquitous presence, the materials used in their production have emerged as a strategic battleground with far-reaching implications.

In recent years, silicon carbide semiconductors have materialized as the industry’s breakthrough material. But while this innovation does gain momentum, an even more promising technology is already developing: synthetic diamond semiconductors. Indeed, this material delivers superior electrical and thermal performance, while dramatically reducing the environmental impact of the manufacturing process.

Synthetic diamond semiconductors represent a true evolution, potentially as significant as the current industry shift from silicon to silicon carbide.

What makes this high-value, environmentally responsible semiconductor material particularly compelling is its potential to be manufactured in Europe, adding a critical layer of technological sovereignty to the dual imperatives of performance and sustainability.

Until recently, innovation had to be economically viable before it could be democratized and have an impact. Sustainability was often a matter of personal commitment or corporate vision. Today, technological disruptions such as the emergence of synthetic diamonds make it possible to have it all.

Beyond industry: a strategic foundation for responsible innovation

Power semiconductor manufacturing encompasses a complex ecosystem of specialized players, each contributing essential skills to the value chain. Europe benefits from a unique advantage: It offers a full range of expertise, from initial concept development to large-scale industrialization, across the whole production chain for these energy transition-critical components.

This extensive capability points to an unavoidable conclusion: Treating the semiconductor industry as just another isolated technology sector is a critical strategic error. Today’s semiconductor industry functions as a pivotal lever connecting innovation, energy efficiency, industrial competitiveness, and continental sovereignty.

Better integrating semiconductor-related issues into industrial and environmental policies therefore means recognizing their role in building a more responsible and resilient economy. It also means ensuring that the innovation choices we make today will serve this meaningful progress tomorrow. Europe holds all the cards. The question is: When will we finally play our winning hand?
