This paper presents an analysis of some significant factors that should be evaluated when considering alternatives to oil burning boilers. Managers contemplating using or increasing the use of wood for energy should find the analysis particularly pertinent. A fundamental assumption of the analysis is that additional boiler capacity is to be added to an existing power generating facility. The method of analysis provides a yearly cash flow stream that tells how much better off the installation would be with an alternative to oil. A logical extension of this is the ran king of alternatives from most to least attractive.
