This energy crisis is taking its toll on me. Going by the sheer no. of mobiles being used today, I just thought about how much energy is required to charge them. If we have 10 cr. mobiles in india and they require 3.7 V @ 100 mA and are charged for 2 hrs. daily. I picked up my calculator and it came out to be a Whopping 74000 units of power per day assuming their are no losses.
