EWEB has stated <br />that growth in electrical demand has been met through a combination of clean energy and <br />conservation for the past decade, limiting the need to purchase electrical power generated from <br />fossil fuel sources. Conservation can play an important role in reducing the per capita level of <br />greenhouse gas emissions, and can help offset overall emissions that are expected to increase <br />with population. <br />5.2 Results by Source <br />To be most effective, greenhouse gas reduction strategies need to reflect the major energy <br />sources producing emissions, and identify those energy sources that are most likely to respond to <br />change strategies. Figure 8 below shows the relative change in the source of GHG emissions in <br />Eugene over the inventory period. <br />An important finding from this analysis of the source data is the shifting role of natural gas. In <br />1990, natural gas is responsible for less than a third of Eugene’s emissions. By 2005, emissions <br />from natural gas are nearly equal to those of gasoline. Projected emissions for 2020 show that <br />natural gas will be the largest share of Eugene’s eC02 emissions given a “business-as-usual” <br />scenario. As previously noted, unlike other areas of Oregon or the nation, electricity is a <br />relatively minor source of greenhouse gas emissions in Eugene. <br />9 <br />
