The 12 state-owned major ports in the country have switched to renewable energy to meet their entire power requirements, making India the first nation to have all government-owned ports running on solar and wind energy. Under a ‘green port’ initiative, the Shipping Ministry had directed all the major ports to install grid-connected and roof-top solar and wind power projects to facilitate day-to-day operations including supplying shore-power to visiting ships in an eco-friendly manner.
