Renewable Roadsides

State highway departments have many responsibilities, from fostering roadway safety to plowing and mowing roadsides to implementing major repair and replacement projects. Often overlooked is the fact that these agencies require significant electricity to power their operations. For example, roadway signs and lights, maintenance buildings, rest areas, and other facilities all require electricity. This article demonstrates how some state departments of transportation have chosen to meet a portion of their electricity needs by installing solar energy projects in highway rights-of-way (ROW) and at other state DOT facilities. Some agencies are finding that pursuing renewable energy generation not only benefits the environment but can also save money on energy costs.The experiences of state DOTs in Oregon, Massachusetts, Utah, and Maryland are considered.
