Queensland Energy Minister Anthony Lynham said the Palaszczuk government's ambitious 50 per cent renewable energy target would squeeze coal-fired power stations out of the state's energy mix, but not until after 2030.

With federal Energy Minister Angus Taylor claiming Queensland and Victoria's renewable energy target could risk the stability of the energy grid,  Dr Lynham said he believed coal and large-scale solar and wind projects could co-exist in the coal-rich state.
