An interesting interview about climate change on four corners with Malcolm Turnbull and a few others:

TRISTAN EDIS, BUSINESS COUNCIL FOR SUSTAINABLE ENERGY: Our electricity greenhouse emissions in Australia have grown 50 per cent since 1990 and ABARE forecasts that they'll grow by another 50 per cent by 2030. So we've got to go beyond what we're doing right now.
JONATHAN HOLMES: Most of the money and attention has gone on new ways of making electricity: clean coal; renewable energy; nuclear power. But they're all expensive. It's much cheaper just to use less, especially in our own homes. Australian households create 20 per cent of the nation's greenhouse gas emissions.
ALAN PEARS, ENERGY EFFICIENCY CONSULTANT: By 2030 with a reasonably strong and comprehensive energy efficiency program household greenhouse gas emissions could be cut by about 30 per cent.
