Irregularity of Energy Resources Distribution

Global resources of hydrocarbons and other (coal, woods, water, etc.) energy sources are distributed irregularly. This depends upon geotectonic position of the region, historical and today’s climatic conditions, and upon some other reasons. Main resources are located in the large troughs of the Earth crust (sedimentary basins) with thick layer of deposits. Today most famous of them are Persian Gulf with vast adjacent territories, Near-Caspian Depression with the northern part of the Caspian Sea, Barents Sea, Western Siberia (central and northern regions) and adjacent offshore area of the Kara Sea. Mexican Gulf with its not yet fully explored resources is also included into this largest category. Further investigations will lead to discoveries of similar large basins in the Arctic too
