The are some of the most useful sites I've collected in my search for evidence supporting, or refuting my interest in biomass tobacco as a renewable energy resource. The current issue features a short summary of my tobacco biomass research. Valuations of damage from emissions to air are based on generic data from other studies. In addition external costs are estimated for nitrogen leaching and for the use of agrochemicals for energy crop production. It is assumed that biomass production takes place on fallow land.
Coal mining is excluded from the analysis.
This excellent Bioenergy homepage is maintained by Tom Jeffries, who knows his way around the internet's energy sites. Good detail on biogas yields of dungs from all conventional farm animals, as well as details on technical aspects of biogas utilization. Another high quality Dutch site. Nevertheless this data offers a useful comparative matrix. This paper explores the economic and energy potential of commercial hemp.
