  • “Who Moved My Btus?” The Pitfalls of Extended Coal Storage

    Many coal power stations have recently been operating at historically low capacity factors or have even undergone extended economic shutdowns. This can result in coal stockpiles that are exposed to the elements for much longer times than anticipated, resulting in a loss of usable coal energy by several mechanisms. This article explores the severity of […]

  • UNESCO Recommends Relocation of Coal Plant in Bangladesh

    In a rare intervention, the United Nations’ (UN’s) heritage conservation arm is urging Bangladesh to relocate a proposed 1,320-MW coal-fired power plant because it poses a serious threat to one of the world’s largest mangrove forests.
