The Association for the Study of Peak Oil (ASPO-USA) is a non-profit education​al organization dedicated to helping America understand and adapt to ​changing realities regarding the cost, demand, and supply of oil.

Founded in 2005 as a network of scientists, researchers, analysts, and other energy observers, ASPO-USA has grown to comprise a wide range of professionals, civic leaders, and concerned citizens.  ASPO-USA maintains a core focus on technical oil issues, but also examines their broader economic, national security, and environmental consequences, and spurs positive action to build a more secure, prosperous, and sustainable future.  ASPO-USA is the U.S. affiliate of ASPO International which has associated organizations in more than 20 countries.
