text: I do and I'm a petroleum geologist. It will be impossible to determine when we actually hit peak until we go down the other side for a while. Most of the major oil companies are failing to replace their annual production with new discoveries, in some cases only replacing 60% of the year's production. As oil becomes more expensive there will be more and more nonconventional sources like oil-shale that come on line, but they will only make the back side of the curve a little more gentle. \n\nThe bigger problem may be the growing demand. World oil demand is at an all time high, over 80 million bbls a day, and shows no signs of demand deflation. \n\nNo, all our resources are not fossil fuels. We need to explore EVERY alternative, including nuclear, solar, wind, bio, tidal, geothermal, etc. Realize that the world's second and third largest oil companies are also the world's two largest manufacturers of solar cells. One of those oil companies is also one of the largest wind power operators in the world. The oil companies see the handwriting on the wall. We need to start saving oil for some of the products other than fuel for which oil is the raw material.
