Fracking good or fracking bad?

At the Feasta climate weekend in Wales last month David Knight gave a presentation on 'fracking': the use of unconventional methods for extracting natural gas.

Knight discussed its viability in terms of energy return on investment, its potential as a pollutant and its effect on climate change. You can download his powerpoint slides from this site now, along with the script he used while giving the presentation.
