In Episode Four, host Jeff Young talks with U.S. Energy Secretary Jennifer Granholm about the difficult task President Biden has assigned her: to cut the use of fossil fuels while supporting the places that dug our coal and drilled our oil and gas. Also: what can Appalachia learn from other places around the globe that closed down coal mines? We'll hear from filmmaker Tom Hansell, who explored how Wales dealt with the end of mining in the United Kingdom, and what lessons the Welsh experience holds for coal communities here.
