The ministry of shipping through its arm Directorate General of Lighthouse and Lightships (DGLL) plans to achieve complete solarisation of lighthouses including Chennai by 31 December 2016.
Most lighthouses operate on electricity with diesel generators as a backup which consume fossil fuel and emit a high amount of carbon dioxide (CO2) causing increased greenhouse effect and air pollution.
In order to reduce CO2 (carbon dioxide) emission, DGLL has decided to replace the source of energy utilised at lighthouses to renewable source and started harnessing solar energy to operate its lighthouses,
Lighthouses operating on a reliable, resilient and renewable energy system would help reduce global warming.
