With ageing nuclear power stations closing down and renewables only meeting a small proportion of British energy needs, what does the future of energy look like? Shale gas is an abundant and potentially cheaper source of energy. In the US 25% of its natural gas comes from shale resources.

These and many more questions are discussed by experts in this debate filmed at the Battle of Ideas. Given the recent Balcombe fracking fracas it's a must see.
