Life Cycle Environmental and Economic Assessment of Willow Biomass Electricity: A Comparison with Other Renewable and Non-Renewable Sources

Previous investigations conducted by the Center for Sustainable Systems (CSS) for the U. S.Department of Agriculture (USDA) have compiled data and analysis on the willow biomass electricity generation system. These investigations have included life cycle energy and environmental impacts of the willow cropping system, and the life cycle profile of electricity generation from willow. These studies compared the willow systems with electricity generation from the national grid and Building Integrated Photovoltaic (BIPV) technology. A more comprehensive analysis of the willow biomass system requires the assessment of additional performance metrics and other environmental, economic, and social factors. In addition biomass technology must be understood in the context of other conventional and alternative technologies. Ultimately, we must consider the question “How can we best leverage our current activities to create more sustainable energy systems for future generations?”
Howard Geller summarized the implications of current energy trends as: high costs, air pollution, global warming, security risks, resource depletion, and inequity. For purposes of this investigation, six electricity sustainability themes have been identified:
1) Maximize return on the investment of fossil resources
2) Minimize emissions of global warming gasses
3) Minimize emissions that degrade air and water quality
4) Minimize land area resource requirements
5) Minimize generating costs while maintaining system economic function
6) Minimize unintended social costs of electricity generation
