Standing in front of Mark Deane’s milking parlour near Carrigtwohill in east Cork, all you see are the shiny black hills across the road from the farm. A few years ago, these fields were growing grass or grain but have now been taken over by solar farms. The same sight is replicated right across east Cork, and indeed in many other parts of the country where solar farm operators are offering over €3,000/ha to lease land for renewable energy.
