I've always been curious why Germany/France/European Union did not try to land lease acreage for solar farms and build the corresponding transmission lines.

To those concerned about sovereignty, costs and jobs, obviously that's not a concern because the alternative Germany pursued was Nord stream which is less sovereign and probably costs more (albeit the Russian oligarchs probably made the initial down payment) and the talent is Swedish.

Or lease space for factories in Spain/Portugal. Similarly, concerns about sovereignty, costs and jobs are moot because the alternative is to build the plants in Asia and ship the cars over.
