Howmet, GE Vernova and Siemens shares fall on Musk solar plan

Howmet Aerospace, Siemens Energy, and GE Vernova shares fell Monday after Elon Musk announced plans for 100 GW of solar production capacity. Howmet dropped 7%, GE Vernova declined 3%, and Siemens Energy fell 4.4%. Musk noted natural gas will still be needed to support solar power and SpaceX will accelerate gas turbine production. Analyst Omid Vaziri said this validates turbine scarcity rather than threatens Siemens Energy.
