It takes 45 million kilowatt-hours of electricity annually to run Oregon's state transportation system -- power that comes mostly from non-renewable sources. Change is underway, however, as the state Department of Transportation is rolling out its first-in-the-nation solar-panel project along a major highway. By December, a row of solar panels about 5 feet wide and two football fields long will be generating about 28 percent of the 400,000 kilowatt hours needed to light the Interstate 5-205 interchange at night. The "all Oregon" effort is a public-private partnership using Oregon companies to suppy materials, design the project and install the panels. This project will generate less than 1 percent of ODOT's annual energy use, but the department will start seeking proposals for similar projects early next year to generate about 4.5 percent of its energy needs.
