Wyn Evans, a dairy farmer from Wales, has seen many changes on his farm over the past 40 years. 

Milder winters, droughts, flash floods, and the erosion of the nearby coastline prompted him to think differently about the farm’s energy consumption -  and potential.

Three decades ago, Wyn created a system which harnessed the methane produced by cow manure, and used to create fuel. Solar panels, a wind turbine and other green resources contribute up to 50 per cent of the energy needed to run the farm.

Russell Beard travels to Wales to meet Wyn, and find out what inspired him to become an ‘energy farmer’.
