Aug 24, 2015· Electricity accounts for 32 percent of a mine's total energy use, so finding ways to reduce energy use can result in significant savings for mining companies. Grinding and ventilation offer the greatest potential for reducing energy use in the coal mining industry, according to an article on the World Coal website.

(PDF) Analysis of Energy Consumption in Surface Coal Mining

Within the figure for coal, hard coal accounted for 12.9% and lignite for 11.8% of total primary energy consumption. Germany is dependent on energy imports to a large extent, except in the cases of lignite and renewable energy. About 90% of hard coal was imported, in comparison with 98% import dependence for oil and 90% for natural gas.
