Anthracite Anthracite Anthracite, often referred to as hard coal, is a hard, compact variety of coal that has a submetallic luster. It has the highest carbon content, the fewest impurities, and the highest energy density of all types of coal and is the highest ranking of coal. Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and
The Carbon Principles The Carbon Principles The Carbon Principles are a series of guidelines established by three leading Wall Street banks — Citigroup Inc., JP Morgan Chase, and Morgan Stanley — to assess the risks in financing electric power projects in terms of climate change. These principles call for "enhanced diligence" in evaluating electric power industry borrowers in terms of their use of energy efficiency; renewable and low-carbon distributed energy technologies; and conventional and advanced generating technologies. These guidelines were announced in February 2008 to address the increasing public concern over the plans to create over one hundred coal power plants in the
