During the last two decades, our country has been indulging in a process of developing a sustainable backup for energy supply.  Studies show that to an extent we have succeeded so far through adopting renewable energy resources like solar, wind, hydropower, etc. as a power backup solution for our energy needs. Solar power got wide acceptance among the public because of its many advantages like simple mechanism, easy installation, long maintenance-free life, durability, and efficiency. 
As we are constantly studying the efficiency of these renewable energy resources under different geographical and climatic conditions, it's important for us to understand their role in disaster response.
