Increasing demand for air conditioners is placing pressure on the electricity grid.
50,000 air conditioners are sold in NSW each year, and this is "This is forcing NSW electricity companies to consider $5 billion in new spending on power stations and transmission lines to cope with the surge during hot weather. Similar problems are being faced in other states."
"Air-conditioners consume about 40 per cent more energy than traditional cooling, such as fans and well-designed, insulated and ventilated houses, says the Total Environment Centre.
The issue is whether it is sensible just to build more network capacity in response to this trend - a cost that will be borne by all electricity users - or to manage the demand, as Sydney has had to do with its water supply."
"There is no equity in the fact that someone can buy a large air-conditioner and impose, say, $5000 of cost on the system, and everyone else pays," said the general manager, network, of Energy Australia George Maltabarow.
