Wind energy is vital in the battle against climate change, but can we make improvements to harness more from them?
Tom Heap visits Kelburn windfarm in North Ayrshire to discuss whether 'wakesteering' - reorientating the turbines could see them harness more power collectively. Meanwhile some potential sites are refused or restricted due to the damage caused to wildlife. Hubert Lagrange talks about his childhood obsession with bats which are often killed by the pressure around turbine blades.
He's worked to develop a system to sense bat and bird activity and allow the turbines to operate longer through a refined system.
Dr Tamsin Edwards discusses how much more potential there is and how much carbon this could save.
