For decades, energy transition experts called for transforming post-mined lands into renewable energy hubs. To bolster their arguments, as part of their “Sunshine for Mines” project, a decade ago the pioneering Rocky Mountain Institute began tracking the few “lighthouse” projects that then existed. At the time, renewable capacity on mine sites stood at just over 600 megawatts worldwide. But by the end of 2019, globally almost 4.9 GW of renewable capacity had been installed or was in the pipeline. And since then, propelled even further by Russia’s invasion of Ukraine and the global response to it, the sheer amount of these second-life projects is increasing exponentially — with Europe and the United States leading the world into a greener post-coal age. In this series, lead author and podcaster, Michael Buchsbaum shines his light on several model solar-centric coal transitions now being developed worldwide.
