BBC2 WEDNESDAY 9pm
Prof Iain Stewart (mbe in the Queen's birthday honours list!) investigates a new and controversial energy rush for the natural gas found deep underground. Sometimes, this is right under the places people live in. Getting it out of the ground involves hydraulic fracturing - or fracking.
Iain travels to America to find to find out what it is, why it is a potential game changer and what we can learn from the US experience. He meets some of the people who have become rich from fracking as well as the communities worried about the risks.
Relevant to A2 geology in particular, Mendip residents, politicians worried about our future energy dependency on other countries and anyone who has (or will have) a gas bill.
