Recently the UK Government halted the moratorium on Hydraulic fracturing, or fracking. leading to questions To Frack or not to Frack. Fracking is a technique for recovering gas and oil from shale rock. It involves drilling into the earth and directing a high-pressure mixture of water, sand and chemicals at a rock layer in order to release the gas inside. The injection of fluid at high pressure into the rock can cause earth tremors - small movements in the earth's surface. The problems with fracking is that the gas is hard to extract. The total amount of gas produced by Cuadrilla from Lancashire could be enough to provide heating and water to 508 3-bed semi-detached houses for 18 days. According to experts, this will do nothing to ease energy prices this winter, however, since it would take many years for an industry to develop and it remains unclear whether a significant amount of gas could be extracted, however it is being seen as part of a new domestic energy security push.
