What exactly is 328 years of anything? Are they saying we consume X tons, and we have found 328×X tons? Or is there some sort of future consumption estimations or trend lines accounted for? Is this all functionally available, or can we only access 20 years worth of it economically and banking on future extraction improvements? With thay large of a supply I would expect economic viability of further extraction would diminish over time.

My interpretation of the image is, “we consume x per year, we estimate there is 328x in the Appalachian area.”
