If there's one energy topic to spark controversy and fierce debate, it has to be "fracking".
Supporters of the process -- which involves fracturing shale through an hydraulic process to obtain oil or gas -- point to the potential for better energy security, cheaper bills, and the economic benefits brought to boom towns such as Williston, North Dakota as reasons for large scale adoption.
Those against argue that pollution, the destruction of the countryside and the threat of earthquakes are all damaging consequences of the technique.
In the U.K., authorities are keen to explore the possibilities of fracking for shale gas, with Prime Minister David Cameron a keen supporter, saying it would, "be good for our country."
A recent report from EY, commissioned by the UK Onshore Operators Group, estimated that a £33 billion ($56 billion) spend could be required to bring U.K. shale wells into production between 2016 and 2032, with 64,000 jobs created as a result.
Could fracking work for the U.K.? "We know there is good organic carbon content, which is encouraging," Glynn Williams, from oil and gas services investor Epi-V, said in a report for CNBC's Energy Future.
"What we understand, however, is that our drilling costs are going to be much higher than the United States… probably the biggest question that has yet to be answered, is 'how much will these wells produce?'."
