The issue of
fracking has received a huge amount of media attention and coverage in recent
weeks and continues to divide the nation’s opinion. The process, which involves
drilling into shale rock and pumping water, sand and chemicals into the ground,
is opposed by many due to its supposed links with contamination of groundwater,
pollution of air by leaking methane and seismic activity. According to an independent
government-commissioned report, two minor earthquakes in Blackpool back in 2011
were attributable to fracking, and this has served to antagonise opponents to
fracking in the UK further.
However,
despite these concerns many others continue to advocate the process of
fracking, claiming it to be a relatively robust and cost effective way of
extracting natural fuel from the ground. The UK government continues to urge
the country to ‘get behind fracking’ in a bid to ensure energy self-sufficiency
for future decades.
So, how exactly
does fracking work? At the most simplistic level, a mixture of water, sand and
chemicals is pumped into ground. The subterranean rock then fractures under the
increased pressure, allowing trapped gas to be released. The gas is then collected
on the surface. The idea is not a new one and has existed in the US since the 1970s,
yet has only recently been put into significant production due to technological
advancements. As well as the UK, many other countries have also recently given
fracking ventures permission to begin drilling in the search for the
much-needed fuel we need to make our society function.
It appears that
whichever technique is used, extracting fossil fuels from the land will always
remain a contentious topic. Although we already have a number of current or
approved fracking sites across Kent, Sussex, Staffordshire, Lancashire, Cheshire,
Scotland and South Wales, as well as more in the pipeline, the future of
fracking in the UK still remains uncertain. The South Downs National Park
Authority recently successfully rejected drilling plans, so the presence of
natural gas does not in itself point to the development of an imminent fracking
site.
However, the
unavoidable fact of the matter is that the need for an independent
energy-supply is ever-increasing, particularly with fears growing of a Russian
gas switch-off. Certainly, more research is needed to make fracking cleaner and
safer and serious attention should once again be given to the development of
new ways to harness renewable sources of energy.
