Energy Efficiency and Climate Protection

We manage energy efficiently

Efficient energy management is a key issue in the world’s attempts to save energy, reduce greenhouse gas emissions and deal with climate change challenges. At Infineon, energy is used mainly in the form of electricity at all steps of semiconductor manufacturing. Primary energy sources, such as oil and gas, play only a minor part.

The majority of energy is consumed in our frontend manufacturing sites. There, energy is required to operate the production equipment, and also to maintain highly sophisticated physical conditions, such as the particularly necessary stable climatic conditions in Infineon’s cleanrooms. Due to their nature, backend processes require far less energy than frontend processes, followed by the development and office sites, which consume the smallest percentage.

We have implemented the systematic energy management system standard ISO 50001, at our main manufacturing sites.

  • Special energy teams at its sites who are responsible for the optimization and continuous evaluation of our energy efficiency.
  • Already in the 2021 fiscal year, Infineon switched to purchasing 100 percent green electricity for its sites in Europe. In the 2022 fiscal year, the North American site in Austin (Texas, USA) followed suit.
  • At our production sites in Dresden (Germany), Regensburg (Germany) and Villach (Austria), significant amounts of heat are already being generated from integrated energy recycling via the recovery of exhaust heat, thereby significantly reducing the demand for energy to produce heating power.
  • At our main manufacturing sites, we have implemented the methodology of the energy management system standard ISO 50001 in accordance with local requirements.
  • The ongoing transition to the latest 300-millimeter technology and the promotion of Industry 4.0 are helping to increase efficiency.

We're proud to have joined RE100

Infineon has joined the global corporate renewable energy initiative RE100, and has committed to using only 100% renewable energy in the future.

RE100 is a global initiative bringing together the world’s most influential businesses committed to 100% renewable power. Led by international non-profit the Climate Group in partnership with CDP, the group have a total revenue of over US$6.6 trillion and operate in a diverse range of sectors. Together, they send a powerful signal to policymakers and investors to accelerate the transition to a clean economy.

We receive excellent results
