Lignite is extracted in the extreme western and eastern parts of the country, mainly in Nordrhein-Westfalen , Sachsen and Brandenburg . Considerable amounts are burned in coal plants near to the mining areas, to produce electricity. Transporting lignite over far distances is not economically feasible, therefore the plants are located practically next to the extraction sites. Bituminous coal is mined in Nordrhein-Westfalen and Saarland. Most power plants burning bituminous coal operate on imported material, therefore the plants are located not only near to the mining sites, but throughout the country.
