Cochin International airport in southern India began adding solar panels three years ago, first they started on the roof of the arrivals terminal and then expanded outward.
Last year, the airport commissioned Bosch to build a vast 45-acre solar plant on unused land near the international cargo terminal.
The project has cost $9.3 million, an amount the airport expects to save in less than six years by not having to pay electricity bills anymore. But more importantly the introduction of the solar plant will avoid more than 300,000 metric tons of carbon emissions over the next 25 years.
