India officially has the first completely solar-powered airport
India's Cochin International Airport is the fourth largest in the world, and the airport just took a big step towards making a difference.
With India as one of the world's three biggest polluters, the airport -- in the southern city of Kochi -- announced on Tuesday that it is now "absolutely energy neutral" and receiving funding from the Indian government through a public-private partnership.
A 12-megawatt solar-powered system supports the airport's energy usage, with more than 46,000 panels installed on the 50-acre site. Ultimately, this environmentally conscious system generates up to 60,000 units of electricity per day.
In total, the project took about six months to build, and it cost $10 million.
Ultimately, India's broader goal is to derive 15 percent of its energy from renewable sources by 2022.
