To help inform the fracking debate, the Energy Institute has published 'A guide to shale gas', which addresses the technological, environmental and legal aspects of exploiting this energy source, produced independently and based on sound science.  This 20-page document explains in factual terms how shale gas is extracted, its impact on the environment and its potential role in meeting future UK energy needs. A guide to shale gas explains what it is and where it comes from – as well as its potential impacts and legal framework. It has been developed from an extensive review and analysis of existing literature and contributions by over 75 subject specialists – including professionally qualified EI Fellows and Members from relevant backgrounds and experience. It has also been subjected to a robust peer review process prior to publication.
