A Biosolar Future for Cities in Europe

  

‘Solar Farms should be on roofs not farms ’ to paraphrase the UK Minister for Energy. The debate on whether farmland should be used for food or renewables is not for these pages. However, whilst there is now guidance on how to make solar farms biodiversity hotspots in the countryside, there is little understanding how this could be achieved at roof level in the UK. In Switzerland specifically there has been much work over the years of combining green roof and solar technology to create roof top biodiversity hotspots.
