So IF (and big IF) the tax gets across at $26/tonne CO2, its likely to favour gas over brown coal, with black coal remaining roughly competitive.
Renewables still have a gap to close unless they can get their costs down. They perhaps may be worse off in some respects as grants funding them will probably be wound back in favour of market pricing.
With higher energy costs consumers may evaluate more energy efficient purchases - cars, white goods, etc.
So my conclusion is that the tax is a good thing for emissions but renewables will still be in the dog house and australian GEL's are still pretty worthless. All the money tipped into them IMHO has been tipped down the drain.
Those seeking their fortune competing against diesel or in markets with better pricing will do well.
