On my todo list is to do a bit more ‘digging’ (forgive the pun) about fracking.
This looks like a good place to start (UKERC links to EU reports so hopefully reasonably unbiased)
The study on energy market impacts shows that unconventional gas developments in the US have led to greater Liquefied Natural Gas supplies becoming available at global level, indirectly influencing EU gas prices.
The study on climate impacts shows that shale gas produced in the EU causes more GHG emissions than conventional natural gas produced in the EU, but – if well managed – less than imported gas from outside the EU, be it via pipeline or by LNG due to the impacts on emissions from long-distance gas transport.
The study on environmental impacts shows that extracting shale gas generally imposes a larger environmental footprint than conventional gas development. Risks of surface and ground water contamination, water resource depletion, air and noise emissions, land take, disturbance to biodiversity and impacts related to traffic are deemed to be high in the case of cumulative projects.
