Indian Navy claimed that the 300-Watt panels will generate about 5.4 kW solar power system, and avoid around 165 kg of carbon a day, "So in its 25 years life the total carbon saved is around 15 lakhs kg and 5.75 lakh litres of diesel by this innovation" [14][15] Noting that the world is looking for clean, renewable sources of energy in order to protect and reduce the harm caused to the environment, the Navy said the deterioration of the environment is highly correlated to the production and usage of fossil-based fuels worldwide. The Navy said it has created a new mechanism to encourage the utilization and development of renewable energy resources.[16]
