Graham Stewart presents the programme from Aberdeen where he's been reporting on the All-Energy 2008 renewables conference. He visits Scotland's second richest man, Sir Ian Wood, who made his fortune off the back of the North Sea oil boom. Sir Ian gives his views on the rising price of oil (which peaked at $135 a barrel last week) and whether renewables can live up to their hype. Julie Peacock reports on the state of the Scottish renewables industry, and Graham is joined in the studio by Jeremy Cresswell, chairman of Aberdeen Renewable Energy Group and editor of the publication Energy.
