Coal: The Energy Source of the Past and Future
W
e are producing and consuming oil faster than we are finding it, and it's essential for the future to find stable, renewable, nonpolluting energy sources. Coal is a good candidate for an energy source to see us through from the decline of the oil economy to the advent of a widespread commercial technology based on new energy sources. This new book takes a look at coal in an enjoyable, easyto-read manner. You'll learn many aspects of this important energy source, including: • how coal is formed
• where coal is found in the world • how scientists study coal • how coal is mined • the many ways we use coal
• how we can use coal in the future It also covers the composition and properties of coal and the chemicals we get from coal. Also illustrated are the use of liquefaction and gasification processes to obtain synthetic fuels from coal. This book is for anyone who wants to learn about the origin, properties, and uses of coal. It will be of special note to legislators, environmental regulators, and economists. by Harold H. Schobert
