an interesting point regarding peak oil....angel publishing puts out a service called The Energy Invester and they have been talking for years about "peak oil"...but recently,they put out a teaser to get new subscribers talking about the U.S. Bakken fields saying that they now are estimated to contain "hundreds of BILLIONS of gallons of oil"....I sent them emails asking about this seemingly contradictory ad but they do not answer (I am a subscriber)....according to the ad,the U.S. geological surveyors or whoever does this kinda thing are increasing the estimated reserves
