Wyoming is threatening to sue Colorado. The reason: Colorado has passed laws that accelerate the deployment of renewable energy and the retirement of coal plants. Wyoming â the nationâs largest coal producer, despite all of West Virginiaâs coal heritage â doesnât like that because it says that hurts The Cowboy Stateâs economy. Thatâs an interesting legal theory and a poor use of Wyomingâs tax dollars. Yes, Colorado might be taking actions to accelerate coalâs decline, but coal jobs would be declining anyway, just not as quickly. Wyoming would be better off figuring out how to adjust to new, and inevitable, economic realities.
