(Aaron Rosenblatt/Daily Republic) Solano board extends moratorium on new wind turbines to April 2023 FAIRFIELD — Solano County supervisors on Tuesday extended a moratorium on any new wind turbines in the county.

That may be limiting the height of the turbines or finding technology that eliminates the conflict with base operations. This slideshow requires JavaScript.
