Here’s a story that should be all about Wyoming.  We have wind and we have coal mines. Yet it was Germany that discovered this.  What this system does is have a wind turbine pump water into a reservoir then the water falls through a turbine in the mineshaft to create electricity.  This allows you to get electricity when you need it and use the energy from wind when you need it without the costly and environmentally unfriendly battery systems.
