Mr Salmond described his digital secret on a visit to Lewis as he announced a further £4 million investment for the Home Energy Scotland Renewables Loan scheme which helps householders cut their energy bills.

He was visiting the Smith family of Ballantrushal who have reduced their utility bills by two thirds after installing an air source heat pump and a 5Kw wind turbine for their home, thanks to a loan from the scheme.
