In South America, coal resources are limited, and this extensive region has only 0.5 percent of the world's supply of coal. Although coal is widely distributed in Perú, Perú ranks thirty-ninth worldwide in coal reserves. Peruvian coal is used mainly for rural domestic use and minor industrial applications that include brickmaking, coal briquettes, metallurgy, cement production, and filters.
