The industry, rightly, is very, very nervous about further interference by the Government in the gas sector and in the energy sector. They're very, very nervous about proposals to build large hydroelectric dams, so large at a cost of billions of dollars—probably more than 10—abating carbon at a cost of maybe thousands of dollars a tonne, rather than the emissions trading scheme's 50. They're so afraid of this interference that they're actually very reluctant to make any investments at the moment, and, in fact, the security of supply that the Minister and the Government are so concerned about is likely to be far more precarious than any estimates they have made.
