Recenzje

"As a reliable and current reference book, the 912–page Encyclopedia of Alternative Energy and Shale Gas contains a total of 76 articles [and] covers multiple important alternate energy and renewable energy sources and shale gas topics...The book...has great value as a current energy reference book in public and university libraries, as well as on the bookshelves of those interested in getting a quick overview of alternate energy sources and shale gas." (The Professional Geologist 23/01/2017)

Overall the book has a lot of information, some of it of interest to the public and politicians and some of it of interest to engineers. For both groups, this is a useful source of information. The articles have full bibliographies so topics can be taken further. (John Goodier, Reference Reviews, Vol 31, No 3)

Dr. Jay H. Lehr received the nation′s first Ph.D. in Ground Water Hydrology from the University of Arizona in 1962, following a degree in Geological Engineering from Princeton University and a few years in the U.S. Navy′s Civil Engineering Corps in the Western Pacific. After Graduate school he taught both at the University of Arizona and Ohio State University before serving 25 years as head of the Association of Ground Water Scientists and Engineers where he was editor of the Journals of Ground Water and Ground Water Monitoring Review. During that period he continued to perform academic sponsored research in many areas of environmental science. Since 1994 Dr. Lehr has been Science Director of the Heartland Institute, a free market think tank located in Chicago, IL, which, through its many publications, provides objective technical information to elected officials throughout the United States.

Jack Keeley is the former Chief of Groundwater Research at the USEPA Kerr Water Resource Research Laboratory in Ada, Oklahoma.

There are few scientific disciplines today which do not encounter energy related questions, problems, dilemmas and obstacles. Mankind requires water and oxygen for life and then energy to survive and prosper. There has been an endless search for new ways in which to create energy. While hope springs eternal for a cleaner energy more dependable source of energy, the manner in which the world is energized has continued to be either hydrocarbon based, nuclear or biofuels along with many forms of renewable energy.

The Encyclopedia of Alternative Energy and Shale Gas is a comprehensive depository of all information relating to the scientific and technological aspects of the world′s energy. The broken into seven sections contains over 75 concise articles.

Written by a committee of the world s leading energy experts, the encyclopedia combines decades of knowledge and experience working with an exhaustive list of energy sources and technologies. Most topics will be prepared as short digestible entries making it easy for users to find the required information quickly, without the need to search through long articles.
