It's a 750KB PDF file.
To summarise, he talks about oil depletion and oil reserves estimation. He states at the end that we have from zero to ten years to make the transition to sustainable energy and put in place energy conservation. He quotes Hubbert's 1949 paper stating that if we do not move to renewable energy and conservation, world population would crash. But if we did, then our future would be sustainable (thousands of years). See for yourself.
