From what I know, wind/solar cannot power industrial needs, only residential. So we can get power at home to heat our house and watch netflix, but there will be no TVs or heaters to run off of the power.
There are utility scale solar plants being planned/built that produce over a gigawatt of power. They rival the output of the largest power plants today. They can absolutely run industrial facilities as well as homes.
Industry often goes to great lengths to rectify 3-phase power. In some cases they'd much rather just have the DC anyway. But that's neither here nor there since utility-scale solar power feeds the AC grid and its alternating electrons are completely fungible and indistinguishable from other electrons.
