Since emissions coefficients were available for the fuels used and efficiency was no longer an issue upstream of the production and distribution of the steam, the input fuel was entered directly into the CCAP software for 1990 and 2005. Projecting the future use of the steam system in Eugene in 2020 proved to be a difficult task. Customers have been dropping off the EWEB steam system causing a cycle of rising cost and further loss of load. EWEB is forecasting a 10% decrease in steam sales over the next 2 years but were not able to forecast beyond. In most cases, customers pulling off the steam system will shift to natural gas for water and space heating needs. For the purposes of this inventory, the decrease in steam was shifted to natural gas use at the rate of 5% per year for the next 2 years, as projected by EWEB, and held steady from 2007 to 2020. Future updates of this inventory will adjust for the status and best known projections of the steam system at that point in time. Sources for this information: Tom Williams, Major Accounts, EWEB. Household Fuelwood The quantity of wood burned in Eugene was estimated using data from the US Census Bureau’s American Community Survey for 1990 and 2005. The survey provides an estimate for the total number of households using wood as a heating fuel in the metropolitan area. Splitting out the number of households by Eugene’s share of the metro area population and multiplying by a statewide average annual household wood use gave us the figures that were used in this inventory. Average annual household wood use was obtained from the Oregon Department of Energy. Projections for use of household fuelwood were estimated to remain at current levels. While the trend from 1990 to 2005, and anecdotal evidence from new building permits suggests that wood use is declining, increases in the cost of home heating fuel may counteract the trend.

Fuel Oil Estimates from US Census Bureau’s American Community Survey for 1990 and 2005 were again used to derive the number of Eugene households using fuel oil.
