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.)
