Scott came under fire after it emerged that he profited from wind energy investments – despite his party having previously opposed the development of such projects. The Register of Interests for Mr Scott states: "From 6 March 2009 part of the Farm’s income comes from a contract with CRE Energy Ltd to provide access over the farm for the purpose of building and maintaining a windfarm".^[9]
