The subsoil has been rich in lignite deposits for the last 50 years, which is at the same time the main source of electricity production throughout the country.
If your cousin Annie has a jet belt-clasp or bracelet, and if you find in aunt Edith's box of old treasures an odd - shaped brooch of jet, you may remember the coal again; for jet is only one kind of lignite, which is a name for a certain preparation of coal.
Former communist East Germany's power industry was heavily reliant on brown coal, or lignite, which is strip-mined in open pits that can sometimes be the size of small towns.
Coal is an impure form of carbon derived from the gradual oxidation and destruction of vegetable matters by natural causes; thus wood first changes into a peaty substance, and subsequently into a body called lignite, which again in its turn becomes converted into the different varieties of coal; these changes, which have resulted in the accumulation of vast beds of coal in the crust of the earth, have been going on for ages.

The company is developing a 4,600-acre mine that would produce about 2.5 million tons of lignite, which is a low-grade coal.
To heat that boiler, the damp, crumbly brown coal known as lignite-which is even more polluting than the harder black anthracite variety-burns in the presence of pure oxygen, a process known as oxyfuel, releasing as waste both water vapor and that more notorious greenhouse gas, carbon dioxide (CO2).
Mississippi Power, a subsidiary of Atlanta-based Southern Co., says the plant would use a new technology that converts a soft coal called lignite into a gas that would fuel turbines to create electricity.
