We need solutions, likely a mix of them, because they all come with challenges: 1) Transmission takes time and $$$ to build (especially to get the land). Maintenance ain't cheap either. Longer transmission == greater losses. 2) CSP requires a specialized site and equipment, with limited generation/storage and greater losses 3) EVs as batteries to back up the grid externalizes battery wear to car owners. To compensate owners would probably cost more than just building dedicated battery back up on the grid (which would be much more reliable). This idea has never made sense to me. 4) Wind is a great resource, but also variable. There will be times when the wind doesn't blow at night.
