Airports around the world are generating solar electricity utilizing the land around their runways and terminal roof space. The energy produced from these solar energy systems is used to power the airport itself or sold to a nearby city. Solar powered airports can now be found in Minnesota, Massachusetts, California, Florida, India, Africa, and the Caribbean. The largest solar array in Minnesota, a 3 MW system, is located at the Minneapolis-St Paul Airport. San Diego International airport is currently installing a 5.5-MW solar PV system that is estimated to provide 10-13% of the airports energy needs. Cochin International Airport, in India, produces enough solar energy to meet all its energy needs. A new study on the potential for solar energy capacity at airports reports that the US could gain a gigawatt in solar capacity if major airports throughout the country installed solar energy systems.
