Coal provides over 23% of global primary energy need and generates about 39% of the world's electricity. |

Currently 67% of global steel is produced in Basic Oxygen Furnaces (BOF); in this process about 0.63 tonnes (630 kg) of coal are used to produce 1 tonne (1,000 kg) of steel. The remaining 33% of steel is produced in Electric Arc Furnaces (EAF); much of the electricity used in this process is generated from coal-fired power stations. |
