State of Non-Renewable Energy Resources at the Beginning of 2014

The latest global estimates of the reserves and resources of fossil and nuclear energy resources are published by the BGR (Bundesanstalt für Geowissenschaften und Rohstoffe; Federal Institute for Geosciences and Natural Resources). So I updated my previous post.
You may find there are two tables below (Due to a technical reason, I couldn't separate them entirely). The first one is in exajoules, just as the source. The second is in million tonnes of oil equivalents. At the beginning of 2014, the world had approximately 73 years' supply of non-renewable energy resources that could be economically exploited with contemporary technologies.
(According to the BGR's glossaries,
Reserves = Proven volumes of energy commodities economically exploitable at today’s prices and using today’s technology (Initial reserves: cumulative production plus remaining reserves);
Resources = Proven amounts of energy resources which cannot currently be exploited for technical and/or economic reasons, as well as unproven but geologically possible energy resources which may be exploitable in future. For coal this term is used for all in-place resources.)
