Biomass is a key renewable energy source expected to play an important role in US electricity production under stricter emission regulations and renewable portfolio standards. Willow energy crops are being developed in the northeast US as a fuel source for increasing biomass energy and bioproduct demands. A life cycle inventory is presented that characterizes the full cradle-to-grave energy and environmental performance of willow biomass-to-electricity. A willow biomass production model is developed using demonstration-scale field experience from New York. Scenarios are presented that mimic anticipated cofiring operations, including supplemental use of wood residues, at an existing coal-fired generating facility....
Present woodfuel usage in Britain is negligible. Historically, Britain has been fortunate in having abundant coal, oil and gas. At an EU level, biomass is seen as an important element of energy, environment and agriculture/forestry policy. In the European context, biomass is taken to include agricultural and industrial wastes in addition to forest woodfuel, and it is regarded as a potential source of heat, fuels and electricity. In the UK, energy policy as a whole is based on four considerations--environment, energy reliability and security, affordability for the poorest in society and competitive pricing for businesses, industries and households. Within UK policy, the dominant driver for greater use of biomass...
In this project on future sustainable transport alternatives a two-step search process has been followed. First an analysis of critical success and failure factors of new technological options in passenger transport is made. These factors are found in the spatial, institutional, economic and social/psychological environment of the transport system. Next, systematically structured and expert based scenarios are con- structed in order to achieve a sustainable transport system in the year 2030 in which possible, expected and desired developments in the distinct fields are analyzed. Finally some policy conclusions are drawn.
