This, the 22nd edition of the World Energy Council’s Survey of Energy Resources (SER), is the latest in a long series of reviews of the status of the world’s major energy resources. It covers not only the fossil fuels but also the major types of traditional and novel sources of energy.

The Survey is a flagship publication of the World Energy Council (WEC), prepared triennially and timed for release at each World Energy Congress. It is a unique document in that no entity other than the WEC compiles such wideranging information on a regular and consistent basis. This highly regarded publication is an essential tool for governments, industry, investors, NGOs and academia.
