Queensland generated 15% of its electricity from renewable energy sources in September and October.
The Sunshine State aims to provide 20 per cent of its electricity from renewables - solar, wind and hydro - by 2020 and 50 per cent by 2030.
While Green Energy Markets believes Queensland will struggle to reach its target, Energy Minister Anthony Lynham remains confident, claiming Queensland is already making the steady transition to renewable energy.
"We already have 30 solar farms, and more than 560,000 Queensland rooftops sporting solar systems, with a combined generation capacity of more than 4000 megawatts," Mr Lynham said.
