How great is home-grown Ross Garnaut ("Taking our chance: the low-carbon future should belong to Australia", November 3)? A giant of a thinker, with oodles of knowledge and experience, Garnaut is more valuable than all of the nation's mineral wealth together.

Even doing our best, with that great head start, the road we are on will probably still be very rugged. Time for Garnaut to guide us, heading an energy/power board. He does not have to reinvent the wheel. - Graeme Tychsen, Rankin Park

I love Garnaut’s vision of Australia as a renewable energy "super-power", and as the world champion in "carbon sequestration" and a "zero-emissions" exporter of processed minerals.

Under Garnaut’s vision, Australia would need to join an international carbon trading scheme, and the federal government would need to seriously subsidise the development and production of renewable energy. Given the attitude of Australian voters, cultivated by the "king coal" Coalition and reluctantly accepted by Labor, neither of these two things will ever happen. - Geoff Black, Caves Beach
