Whether enough new sources can be found to delay an energy shortage, it could be possible. I suspect they are out there: will they be tapped in time. certainly the new reserves in Alaska are miniscule- if that is what you are refering to? Renewable is the way to go, along with totally new energy sources- sep[erate of petroleum. We wiped out U.S. reserves in 100 years. We can't do it in the rest of the world in 100 years. U.S. energy reserves fell fast after 1967.
As to "BrainFart," I need to renew my reading of their research. I for one believe them over your information sources. They were credible.. That I am sure. It was a study commissioned by the British government.
Even the main street media has commented about how small the reserves are in Scotland, Canada, Mexico, and Venezuela.
These reserves are gone we are more dependent upon sources who do not particularily like us ! Maybe you think our military can control them indefinitely. I disagree. Besides buying these energy sources is depleting our international balance of payments, which will devastate our economy. Don't believe Brain Fart. I do. The research was completed by economists at the University of London as I recall.
