Instead of coal-fired power plants, the horizons are now dotted with wind turbines and fields full of solar panels. While about 22 percent of Germany's electricity still comes from burning lignite — and a further 12 percent from hard coal — some 33 percent is now generated using renewable energy.

Why is lignite coal bad? Lignite's high moisture content and lower carbon content results in more carbon dioxide emissions than harder black coals. In these power plants the coal is burned and used in industrial boilers. What are the negative effects of coal? Several principal emissions result from coal combustion:

Anthracite coal is a dense, clean to touch, and hard rock with a jet-black colour. It is normally non-agglomerating, non-clinkering and free-burning coal because when it is ignited it does not coke or expand and fuse together. It has a low percentage of ash and a high ash fusion temperature.

Coking coal is best if it has a very narrow range of volatility and plasticity. This is measured by the free swelling index test. Volatile content and swelling index are used to select coals for coke blending as well. Volatility is also critical for steel-making and power generation, as this determines the burn rate of the coal.

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat.It has a carbon content around 25-35%, and is considered the lowest rank of coal due to its relatively low heat content.When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content.
