John Bell (pictured) has written a script for a television advertisement that begins: "I am planet Earth".

The artistic director of the Bell Shakespeare Company was one of several speakers at the May 9 Smart Energy Conference and Exhibition in Sydney, which was in fact, the 60th conference organized by the Smart Energy Council, a fact proudly pointed out by the council's Chief Executive, John Grimes.

Among the speakers was the founder and chief scientist of "Otherlab", Saul Griffith, who talked about "Rewiring Australia".
