Energy efficiency: the smart way to cool the climate

Climate change Australia

Jane Castle argues that we can stop catastrophic climate change and maintain our standard of living by transforming how we do things, not just by changing what we do. This is what the respected McKinsey Report on the cost of greenhouse reductions for Australia tells us. For Australia to reduce its greenhouse emissions by 30 per cent by 2020 compared to 1990 it would only cost $290 per household annually and the growth of GDP would slow by a mere 0.02 per cent each year. More striking, however, is that one quarter of the emissions reductions are cost-negative. That is, they create substantial savings while reducing emissions, and the technologies to achieve them are available today.
