Coal can generate up to 1/5 of global greenhouse gas (GHG) emissions. Substitution of coal with biomass fuels or natural gas is one avenue to reduce GHG emissions. The EROI and life cycle of wood pellet firing and co-firing with coal generating stations (GS) and gas stations are examined. GHGs and EROIs are compared with current coal and hypothetical natural gas combined cycle facilities are the focus of this discussion. The potential for increased EROIs and reduced GHGs, for example by increased biomass utilization in coal as one strategy to increase EROIs is discussed. The scenario of limited feedstocks contributing to higher usage costs and lower returns is also discussed and a roadmap towards sustainability offered.<br/>

Coal vs. gas: Are we condemning our grandchildren to feedstock poverty?
