It's too late.
Oil will eventually rebound in price. The current low oil price wont last for more than 2 years.
Low oil is here to stay for another 5 years.
We won't see $100 again.
It will be $25 to $60 from now on
Why? Look at the price history of crude oil. It has been doing this forever and always made new all time highs within a couple of years.
AJ is right we're too late because another reason is the ITER Fusion Reactor that they are building, if the experiment succeeds say goodbye to the use of oil and about selling it too!
