Steve Reed 218 E. Charles Oelwein, IA. 50662 319-238-1822 IOWA BIOMASS PROJECT MANAGER By limiting the size of the towns to 10,000 population restricts the size of renewable Energy Systems you can deployed. Biomass that is produced in towns on an annual basis is fairly constant including leaves from trees. But for years after disasters the biomass will be decreed. So when sizing a system, you should leave a 30% buffer of biomass in case of storm damage decreases. Biomass from surrounding areas that can be used as supplemental. But the farther you have to transport biomass. The more it will cut into your profits. Just like palletizing leaves and sawdust will add cost. But it will increase your fuel sources considerably.
