The US now imports half its oil and fracking constitutes half of current production.   Conventional oil production is declining and has been since around 1970 so any increase has to come from tight oil.  ie fracked production has to triple.  A very tall order and given the depletion rate for fracked wells of around 70% annually, very tough to maintain.

US proven reserves are somewhere between 30 and 45 billion barrels while annual consumption is close to 7 billion barrels.  How does any of this add up to energy independence?  I wonder what numbers Trump is working with?
