Earlier this year two books were published,
The Last Oil Shock by David Strahan and
The Battle for Barrels by Duncan Clarke. Both books address the question of future oil supplies but came to dramatically differing conclusions; Strahan arguing global oil production will soon peak and go into terminal decline, Clarke highlighting complexities concerning the evaluation of how much oil remains, historical mistakes in production forecasting and suggesting a more abundant view of our energy future.
In August David Strahan wrote an open letter to Duncan Clarke. It can be read
here.
In September Clarke responded with a letter of his own, read his reply
