World Reserves of Fossil Fuels

BP's "Statistical Review of World Energy" published in mid 2013 says that the world has in reserves 861 billion tonnes of coal, 187 trillion cubic meters of natural gas, and 1669 billion barrels of crude oil.

These numbers seems to be huge at a glance, but taking into account today's level of extraction proved reserves of coal will be exhausted in 109 years. The last cubic meter of natural gas will be extracted in 2068. And by 2065 there will be no reserves of crude oil.
