Industrialized societies depend on non-renewable energy sources. Fossil fuels are ... The softest coal (about 50% carbon), which also has the lowest energy output, is called lignite. Lignite has the highest water content (about 50%) and relatively low amounts of smog-causing sulfur. With increasing temperature and pressure,
