The state government's decision to dump the position of parliamentary secretary for renewable energy is a victory for the fossil fuel lobby and leaves NSW without a stand-alone voice to address renewable energy, Greens MP John Kaye says.

The position has been dissolved after the promotion of Nationals MP for Port Macquarie Leslie Williams to the portfolios for Early Childhood Education, Aboriginal Affairs and Education. It was previously held by Planning Minister Rob Stokes.

It is one of five parliamentary secretary positions to be left behind by the new Baird government, along with police and emergency services, planning, tertiary education and skills and regional and rural affairs.

The move has industry figures and Greens MPs concerned for the future of the state's focus on renewable energy.
