The need "to be independent of the electricity utility grid" led to the actualization of Cochin International Airport in southern India, the world's first fully solar-powered airport.
German company Bosch was commissioned in August 2015 to build a vast 45-acre solar plant project on unused land near the international cargo terminal of the airport which costs around 620 million rupees ($9.3 million).
...$9.3 million you say?, well Cochin International Airport authorities say they expects to save that amount in less than six years by not having to pay electricity bills anymore; more so, the solar plant is estimated to avoid more than 300,000 metric tons of carbon emissions from coal power over the next 25 years. Nice move....
