Sorry bro, you need read up more on the topic.  It isn't worth anyone's time here explaining Bitcoin use cases to you, when you're either trolling or lack the initiative to research the topic yourself.  Unless you want to pay me in bitcoin, of course, for an hourly consulting/mentorship gig?    

Just let me know and I'll shoot you my Skype name and BTC address.

EDIT: Also google "opportunity cost".  No one will otherwise take your arguments concerning energy consumption/waste seriously.
