By sea, Oregon is well served by freighters that enter the port of Coos Bay and the various ports on the Columbia River from Astoria to Portland. Above Portland, barge transportation is important on the Columbia River. Barges also use the smaller coastal harbors of Tillamook, Newport, Florence, Reedsport, Gold Beach, and Brookings.
Oregon had 96,171 km (59,758 mi) of highways in 2007, of which 1,173 km (729 mi) were part of the federal interstate highway system. The principal route north-to-south is Interstate 5, and the main road east-to-west is Interstate 84. The two roads meet in Portland.
Some 3,993 km (2,481 mi) of railroads served Oregon in 2004. Wood products accounted for 50 percent of the tonnage of freight originating in the state, and paper products made up another 13 percent.
In 2009 the state had 10 airports, many of which were small private airfields. The principal airport is in Portland, although air routes form an important transportation link for other cities in Oregon.
Hydroelectric power plants generate 63 percent of the electricity produced in Oregon. In the late 1990s Oregon ranked second in the country in the generation of hydroelectric energy, behind only Washington. The Columbia River basin, which Oregon shares with several other states, contains one-third of the hydroelectric energy potential of the United States.
The Columbia River furnishes much of Oregon’s hydroelectric energy. Along the river on Oregon’s northern boundary are the Bonneville Dam, east of Portland, the Dalles Dam, the John Day Dam, and the McNary Dam, which is near Umatilla. Dams in the Columbia system outside of the state also feed power into Oregon. The remaining small share of electricity generated in the state comes from facilities burning fossil fuels, principally coal and natural gas. The state’s sole nuclear power plant, near Rainier on the lower Columbia, has been closed. "Oregon" © Emmanuel BUCHOT, Encarta, Wikipedia
