EROEI Energy returned on energy invested, it's not the gross but the net amount of oil that matters, you can quote all the figures you like about how much we are producing today against what we produced in the past, it's when the EROEI gets down to 4 or 5 to 1 that the wold as we know it ceases to be, it is estimated from the worlds depletion figures the falling EROEI ratio will be 1 to 1 in around 25 years barring economic melt dawn slowing the use of oil. of course we can't run on anything close to that, we should scrap the car and go over to electric bikes and build up an electrified rail net work. Oh dear we have left it to late.
