Fracking is the
main reason as to why America is having an energy revolution. Engineers and
Scientists have worked hand in hand to produce safe hydraulic fracturing
practices which have minimum impact on the environment. The US is now able to
tap a vast amount of oil and natural gas reserves which were once considered difficult
to reach (shale locked reserves and tight rock formations), hence were deemed
not economically viable. The process has also been used in stimulating production
from older depleting wells. Some sources claim that >95% of natural gas
wells to be drilled in the future will be done through hydraulic fracturing. In
the UK, this is being considered amidst opposition from environmental pressure
groups.
In the US, the
IEA predicts that Americas total gas production will increase by 56% by the
year 2040, with majority of the gas coming from shale gas.
Fracking in the
UK is only at exploratory phase despite shale gas reserves having been
identified. Although over 100 licences have been given for exploration
activities, firms also must receive planning permission from the relevant local
authorities if they are to begin fracking. Fracking sites in the UK include
Lancanshire, Yorkshire and Nottinghamshire.
Some
environmental pressure groups and governments fear that tremors induced by
fracking can result in structural damages above ground. Some have even
highlighted poisoning of underground water sources by the chemicals/additives
injected during the fracking process. There are also claims that fracking utilises
huge amounts of water, at a significant environmental cost. Furthermore, it is
feared that carcinogenic chemicals used in the process could escape into
groundwater sources around the fracking site and contaminate them.
Supporters of
renewable energy sources state that this is an unwelcome distraction as energy
firms and finances continue investing into fossil fuels hence encouraging the
continued reliance on fossil fuels.
However despite
all this, fracking has proved to have its own advantages. For example, the
increased oil production observed in the US has driven down gas prices. Not
only are low pump prices being enjoyed in the US, but also globally. It is estimated to have offered gas security to the US and Canada for
about 100 years. As for the UK, fracking could contribute enormously to UK’s
future energy needs given the maturity of its oil and gas reserves in the North
Sea.
In conclusion,
fracking will be the engine in the world’s future energy revolution.
