The most popular view among the general public, including research scientists, is that growth will continue practically indefinitely. Let’s call this Scenario A. This forecast by Price Waterhouse Coopers might be typical of what one would expect: These growth rates don’t look all that high when presented on an annual basis, but they really add up over time. At an annual growth rate of 7.6%, India’s GDP in 2050 can be expected to be 27 times its real GDP in 2005. At an annual growth rate of 0.8% per year, by 2050, India’s population can be expected to 43% higher than in 2005. A second scenario, which I call Scenario B, is one that is held by quite a number of people who have been studying oil and gas depletion models. It is focused on an expectation that oil and gas production in the future will follow a pattern such as this one prepared by Colin Campbell, taken from the April 2009 ASPO-Ireland Newsletter.
