Graphic: how shale gas is extracted through fracking


The UK has an estimated £1.5 trillion worth of underground shale gas deposits, which could "contribute significantly to our energy security, reducing our reliance on imported gas, as we move to a low-carbon economy," said Mr Davey.

The extraction technique, known as "fracking", is controversial due to the toxic chemicals and amount of water needed to release the trapped gas, and the subsequent risk of seismic activity.
