There's a huge "wind belt" running north from the Texas panhandle up to Canada. At one time, T. Boone Pickens was looking into exploiting this, but he went for oil instead. There's no big electrical load in that area, so high-voltage DC lines to the West Coast, east to the Midwest, and south to the major Texas cities would be needed.
2,000 km transmission lines are now routine.[1] They've taken 2-4 years to build in Brazil and China. So this is quite feasible.
Politically, building long-haul transmission lines in the US is a huge hassle. Efforts to build a 730-mile line between Wyoming and Nevada (where it can attach to existing lines to California) have been underway since 2013, one jurisdiction and landowner at a time.[2] And this for something which is completely non-polluting. It's DC; you don't even get induced stray voltages.
