David Strahan has been a professional writer for over thirty years. He learned his trade through the exacting discipline of writing for television, first as a reporter for Thames TV, and then as a business correspondent and producer-director at the BBC. For ten years he made investigative documentaries for The Money Programme and Horizon, until leaving to write The Last Oil Shock (John Murray Ltd, 2007). Since then he has worked as a writer and editor specialising in clean energy, including journalism for Bloomberg New Energy Finance and New Scientist, and commercial reports for clients including Dearman and the University of Birmingham Energy Institute (see services). He now also teaches clear writing for productivity through write first draft.
