Airports have implemented a variety of renewable energy technologies since 1999—with the largest growth occurring over the past decade—in parallel with the evolution and maturation of renewable energy markets. Of the renewable energy options available to airports today, the prevailing technology is solar photovoltaic (PV), which accounts for 72% of all projects cataloged in the Renewable Energy Projects Inventory.

The TRB Airport Cooperative Research Program's ACRP Synthesis 110: Airport Renewable Energy Projects Inventory and Case Examples draws on existing literature and data to present the state of practice for airport renewable energy. It presents the integration of renewable energy projects—including solar PV, geothermal, bioenergy, solar thermal, and small wind projects—into airport development and operations and the drivers behind those efforts.
