The Productivity Commission's objection to the MRET seems to be based on the view that it edges out gas for electrical generation. My counter argument is 'just look at the UK'. A more sophisticated argument might be that we can afford to build wind and solar now and we might be too broke to do that when gas supplies are low. Not having the Commission's report I don't know if they have done any crystal ball gazing about ammonia/urea production, CNG as a heavy vehicle fuel or diesel substitute, GTL petrol and avgas, gas fired CHP in cities and more use of gas peak power to balance wind and solar. In other words there are much better things to do with gas than centralised baseload generation.
