Which role plays renewable energy in Australia, now and in the future?

On 23 June 2015 Australia’s Parliament revised the RET’s
2020 target for energy from large scale renewable projects
from 41 000 gigawatt hours (GWh) to 33 000 GWh. On
current estimates, this target would result in 23.5 per cent
of Australia’s electricity generation in 2020 being sourced
from renewables.11
