ASPO

The Association for the Study of Peak Oil and Gas, or ASPO, is a network of scientists, affiliated with a wide array of global institutions and universities, whose goal is to attempt to determine the date and impact of the peak and decline of the world’s production of oil and gas, due to resource constraints.^[1]
ASPO was founded by Colin Campbell in 2000. It is the most influential organization supporting the "peak oil" theory, meaning that future oil supply will be much less than commonly expected. Their studies use the Hubbert curve, devised by M. King Hubbert, among many other methods to which predict future oil availability. It is a common misunderstanding to believe that ASPO and peak oil only is about the Hubbert curve.http://en.wikipedia.org/wiki/Association_for_the_Study_of_Peak_Oil_and_Gas
