Impacts of a Snake River Drawdown on Energy and Emissions, Based on Regional Energy Coefficients.

摘要

The latest discussion on salmon recovery efforts in the Columbia-Snake River centers around breaching Lower Granite, Little Goose, Lower Monumental and Ice Harbor dams on the lower Snake River in eastern Washington. Snake River barge transportation is an important mode of transportation for the eastern Washington grain industry, and disruptions in barge service due to breaching are likely to have economic and environmental effects since the grain which is currently transported by barge must then rely on rail or longer hauls by truck. This study uses regionally specific coefficients to determine the impact on energy consumption and emissions production of a drawdown of the Snake River. The coefficient results as well as the impact magnitudes are then compared to the national coefficients analysis.
