Queensland and New South Wales are set to fall short of their greenhouse gas reduction targets according to the Green Energy Markets advisory group but research found Victoria, South Australia and Tasmania are on track to hit their goals.

The Queensland government wants renewables to make up 50 per cent of the electricity mix by 2030 but based on existing wind and solar commitments, are currently tracking towards 29 per cent, a figure rejected by the Queensland energy minister.

The lack of a national renewable energy policy means state policies are the key drivers of investment in green energy generation for the country.
