The report looks at the technologies available to generate energy in the highway context and also qualitatively assesses the opportunity to reduce the energy used by existing highways infrastructure.

Case studies related to some potential technologies and techniques are presented: thermal collection, photovoltaic collection, wind microgeneration, water microgeneration, efficient use of new materials.

There exists a variety of different ways in which energy can be generated by innovative use of the existing highway infrastructure and land holdings associated with highways. There are however also barriers to implementation which are identified by the report.
