Are there any renewable energy companies manufacturing in the US? Seems like all are downstream of that, just providing installation and management. Actual energy security should include some meaningful domestic production.
Illuminate USA in Ohio claims to be going even bigger than T1. Over 5 GW/year (10 million panels). But they just seem to manufacture panels and not batteries.
Some others include: Tesla, Qcells, Mission Solar, First Solar, Ambri, Enphase, Ørsted, TotalEnergies, and Generac.
Not all are fully vertically integrated and many still rely on global supply chains...
