Inside Climate News has compiled a map of the nation’s fracking activity. There are “22 states, from California to Texas, Michigan to West Virginia, currently employing this high-intensity form of energy extraction, and five others may soon follow.”  

“Fracking is used differently in each state, depending on the available fossil fuels. Texas has thousands of wells that tap into deeply buried shale deposits. By contrast, in Indiana, fracking occurs for a small percentage of wells.”
