Why it's on ClimateTicker

Siemens Energy is a genuine enabler of the energy transition through its grid technologies, HVDC systems, power transformers, and wind subsidiary Siemens Gamesa — infrastructure that is structurally necessary to connect and transmit renewable power at scale. However, a material and growing share of its revenue comes from fossil gas turbines and services, with the company nearly doubling gas turbine unit sales in FY2025, creating a real tension between its 'green' marketing and its full portfolio. Investors should treat Siemens Energy as a mixed-portfolio industrial undergoing a transition, not a pure-play climate company.

enablerSiemens Energy sells and services energy technology equipment (gas turbines, transformers, HVDC systems, wind turbines via Siemens Gamesa, electrolyzers) and software/services across the full energy value chain, generating €39.1 billion in FY2025 revenue from four segments: Gas Services, Grid Technologies, Transformation of Industry, and Siemens Gamesa.

Controversy & Greenwashing Watch

mediumNGO greenwashing pressure at 2026 AGM over fossil gas expansion

Urgewald, Beyond Fossil Fuels, Greenpeace Germany, and other NGOs publicly challenged Siemens Energy at its first public AGM, citing a contradiction between its 'energy transition' branding and surging gas turbine sales driven by data-center power demand.source ↗

mediumSF6 greenhouse gas use in grid products

Siemens Energy's grid switchgear portfolio still relies on SF6 — a potent greenhouse gas with ~23,500x CO2e warming potential — though the company has committed to an SF6-free 'Blue Portfolio' across all relevant voltage levels by 2030 at the latest.source ↗

highSiemens Gamesa quality crisis and multi-billion euro losses

Siemens Gamesa suffered a major onshore turbine quality and warranty crisis leading to billions in losses and a near-complete sales stop for onshore platforms, damaging financial credibility of the renewables segment.source ↗

mediumFossil fuel operations scrutiny at spin-off listing (2020)

At the time of its 2020 Frankfurt listing, climate activists criticized Siemens Energy for supplying turbines to coal plants in Indonesia and involvement in a gas-fired plant in Israel, among other fossil fuel activities.source ↗
