“Transportation is one of the most significant factors of human influence on our planet. This map of the human footprint shows the gradient of human impact within the state of Oregon. This map is a unique view of human impact that demonstrates the Oregon Department of Transportation’s (ODOT) dedication to renewable energy.
“It takes 45,000 megawatt hours of electricity annually to run Oregon’s state transportation system. This energy is used for signals, illumination, buildings, ramp metering, and more. Historically this energy comes from mostly nonrenewable sources. ODOT supports efforts to reduce greenhouse gas emissions and is planning for the transition to alternative, renewable fuels that will be required for the future.
“Oregon’s governor has directed state agencies to secure 100 percent of their electricity from renewable sources, and ODOT is responding by developing the nation’s first solar highway. With 16,000 lane miles of right of way and many other properties under its ownership, ODOT buildings and lands provide a ready asset for the development of solar energy. ODOT also has active projects involving electric vehicle charging stations, alternative fueling sites, and an environmental data management system to help preserve natural and cultural resources.
