Baseload is the demand side of the equation. Sure, no single wind or solar farm can meet localized baseloads over a 24 hour period, like a single nuclear or hydro station can. However, given distributed solar and wind turbines at sites across 1000s of kilometres, working in conjunction with high voltage 700+ kV transmission, it is possible. Hence my assertion that the problem is social/political, and not a technical/physical limitation.
